South Africa is not just another developing country struggling to govern artificial intelligence (AI); it is the exception with leverage, and the window to act on it is closing. It holds approximately 88% of global platinum-group metal reserves, critical inputs to parts of the semiconductor and data center supply chains that make AI infrastructure possible. It hosts the largest data center market on the continent. Its existing hyperscaler relationships give it procurement leverage that most African states will never have. And a major geopolitical contest over AI infrastructure is being fought on its soil right now, between Chinese and American technology companies competing for control of the systems that will underpin an entire continent’s public sector.

In physics, leverage requires three things: a fulcrum, a lever arm and the ability to apply force. The Bushveld Complex, the world’s largest platinum-group metal deposit, is the fulcrum: a mineral endowment that gives South Africa a position in the semiconductor supply chain that no other African state holds. The since-withdrawn draft policy is the lever arm. The unresolved “OPTION” provisions in the policy are where force would be applied. Without a policy that specifies what South Africa wants in return for market access, the lever arm sits unused, and the weight of two of the world’s largest technology ecosystems settles exactly where those ecosystems want it to settle.

This makes South Africa a global test case. Not because its proposed means of governance is exemplary, but because it is the one developing country with enough structural leverage to negotiate genuinely different terms, and the one that is choosing, through inaction, not to. The recent announcement of a new panel to update the draft policy is an important opportunity. But the deeper failure is not that an AI policy contained bad references. It is that no verification process caught them before the document entered the public domain. That is a systems problem, not merely a political one. It points to a missing layer in how governments are adopting AI.

The contest already underway

Last year, Huawei, pitched an emerging product bundle to tech executives across the continent. Huawei was now bundling access to the DeepSeek’s large language model with its own cloud and storage infrastructure. The price differential was stark: in some cases by more than 90%.

At the same time, Microsoft announced plans to spend ZAR 5.4 billion ($300 million) by the end of 2027 on cloud and AI infrastructure in South Africa, building on a prior ZAR 20.4 billion investment. Google, AWS and Oracle already have cloud regions in the country. According to one analysis, the country’s data center market was valued at $2.16 billion in 2024, the largest in Africa.

These are not commercially neutral investments. Huawei’s infrastructure reach has been explicitly linked to Chinese strategic objectives, including a documented track record of providing governments with surveillance infrastructure through its Safe Cities network. US hyperscaler investment comes with its own dependency structure: closed models, pricing set unilaterally and terms of access that no African government has meaningfully shaped. South Africa is being asked to choose between these dependency models without a policy that specifies what it wants in return.

The leverage it has

There is a particular irony in South Africa’s position. The country whose mines supply platinum-group metals essential to semiconductor manufacturing, and through them to AI compute, has drafted a policy that treats it as a consumer of AI systems rather than a stakeholder in their governance. South Africa digs up the minerals that make AI possible. It has no say over the AI built from them.

The AI triad framework covers algorithms, compute, and data. South Africa has no frontier model development capacity. South Africa holds significant data assets in financial services, healthcare and agriculture, with no clear framework for their sovereign management. South Africa possesses PGM leverage of global significance on the compute axis, currently being transferred without meaningful condition. It also has exceptionally high solar irradiance and significant renewable energy potential. A country that can offer both critical mineral inputs and the energy to power the infrastructure those minerals help build occupies a negotiating position of unusual strength.

The Draft Policy proposes no minimum terms for hyperscaler investment, no data sovereignty requirements, no technology transfer conditions and no compute visibility mechanism. Multiple provisions are explicitly left unresolved, marked “OPTION”, including the most consequential choices about how governance will function. Infrastructure decisions made now determine what is renegotiable later, and the answer is: very little.

Three futures, one default

The three infrastructure futures on offer each create a structurally different form of dependency, and only one creates sovereign capability. The Huawei-hosted DeepSeek integration offers low cost and open-source weights, but with data stored on infrastructure potentially accessible under Chinese legal frameworks, creating surveillance dependency in a pattern already documented across Africa. The second is US closed-model dependency: higher capability, more reliable data protection, but complete API dependency on developers abroad. The third is locally hosted open-weight infrastructure: models governed under South African data sovereignty rules, on infrastructure subject to minimum terms, developed with South African data. As Nathan Lambert at Interconnects has observed, open-weight models are likely the only realistic way to get sovereign AI off the ground as a real effort, enabling local communities and economies to integrate meaningfully with the technology. But this requires procurement conditions, not goodwill.

What binding governance looks like

The GovAI “Governing Through the Cloud” framework identifies four roles compute providers should accept as conditions of operating at scale: securers (protecting model weights and training data), record keepers (maintaining infrastructure usage logs), verifiers (confirming customer compliance with safety standards) and enforcers (restricting access when violations occur). These are operational requirements, not theoretical categories — specific, enforceable, and well within the bargaining power of a market of South Africa’s size and mineral position.

A detailed policy analysis submitted to the Department of Communications and Digital Technologies (DCDT) identifies the specific provisions the final policy must contain: mandatory minimum terms for foreign compute infrastructure investments above ZAR 500 million (~$30 million); a compute reporting threshold; a National AI Safety Institute mandate covering defensive monitoring of AI capability accumulation; and National AI Champion Sector designations to create data assets for domestic model development. Each provision converts a structural advantage into a governance instrument before that advantage is foreclosed by market reality. Just as modern software security increasingly depends on knowing what components are inside a system—model provider, training data, compute environment, evaluation methods, update cadence, human review points, and failure-reporting procedures—public-sector AI governance requires a clear account of the stack before deployment, not after a problem surfaces. A public institution that cannot verify the sources in its own AI policy is unlikely to be ready to verify the AI systems it procures, deploys, or regulates.

Why this is the continental test case

South Africa’s choices will establish a regional precedent for what is commercially negotiable in AI infrastructure. If South Africa negotiates data sovereignty guarantees and technology transfer conditions as requirements for hyperscaler investment, it creates a replicable model. If Microsoft’s $300 million investment and Huawei’s infrastructure expansion proceed on standard commercial terms, as they are currently, it normalizes extractive AI infrastructure across the continent. The lesson is not specific to Africa. Governments everywhere are producing AI strategies while lacking AI assurance infrastructure. South Africa is an early warning, not an isolated case.

The public comment period closed when the policy was withdrawn. But a parallel process remains live: the National Treasury’s Draft General Public Procurement Regulations—the legal instrument that will govern every government AI contract—closes for comment on June 15. Those regulations contain no AI-specific provisions.

South Africa has more AI leverage than any country on the continent. Some argue, with force, that governance requirements risk deterring the infrastructure investment South Africa urgently needs: compute capacity, reliable energy, venture capital, and talent retention. That concern deserves a direct answer. Minimum procurement terms, compute reporting thresholds, and technology transfer conditions are not barriers to investment. They are the conditions under which investment serves the host country rather than extracting from it. Infrastructure built without minimum terms produces dependency. Infrastructure built with them produces leverage. To serve the public interest, its AI policy must use it.

On a sunny Tuesday afternoon in May, San Francisco Bay is busy. Container ships the size of skyscrapers deliver their wares to the Port of Oakland, tankers bear fuel, and ferries carry tourists to their hikes and commuters to their jobs at AI startups. Looking down at this marine traffic from Angel Island, located near the entrance to the bay, a group of excited scientists point to some sparkles on the surface of the water: Three gray whales are coming up for breath.

A collaboration of government agencies and scientists hopes to keep interspecies traffic running safely, thanks to an AI-based whale detection system that launched on 19 May. Developed by WhaleSpotter, based in Somerville, Mass., the system uses an AI model to detect whales in footage from thermal cameras looking down at the bay from Point Blunt on Angel Island. Detections are verified by a human to prevent false alarms. Then the system warns nearby ships so they can slow down or reroute. While trained humans can spot the spray that whales produce when they exhale, thermal cameras powered by AI do an even better job—and they can keep an eye out 24/7, even at night and on foggy afternoons.

For many whales, a trip to San Francisco is the end of their journey. A study published in April estimates an 18 percent mortality rate for gray whales that enter the bay. Seven have died here so far in 2026. In 2025, a record 21 gray whales died in and around the bay, and necropsies showed that 40 percent of those deaths were caused by ship strikes. “Last year was truly a crisis for gray whales,” says Douglas McCauley, director of the Benioff Ocean Science Laboratory at the University of California, Santa Barbara.

The Bay Area is a new stop on gray whales’ route. They make the longest migration of any mammal, traveling between 15,000 and 20,000 kilometers round-trip from Alaska down to Baja California, Mexico, to breed. Historically, they made no stops along the way, gorging before their departure, then fasting on the journey.

Since 2018, however, over 100 gray whales have detoured into the San Francisco Bay on their way back north. Scientists aren’t sure why they are stopping, but they suspect it is because record-low sea ice levels driven by rapid climate change are to blame. The theory is that it’s decimating the algae that fertilize the Arctic food chain gray whales rely on. Instead of heading south with a full tank, the whales may not be able to eat enough to sustain their entire migration, so they come to San Francisco Bay for a snack on the way home. Some end up staying for over a month.

“Gray whales are trying to be a brave new whale in a weird world,” says McCauley. Standing next to WhaleSpotter’s thermal camera, looking down at the bay, he says this is “a front-row view to climate change.” From its mount on a Coast Guard tower on Angel Island’s Blunt Point, the camera captures images covering a cone of water extending out about 7 km.

AI Thermal Cameras Detect Whale Spouts

When whales come up for a breath, they expel a jet of air that’s hotter than its surroundings. WhaleSpotter’s technology was initially developed at the Woods Hole Oceanographic Institution in Massachusetts to recognize these distinctive spouts, even if they show up only in a pixel or two. The footage is then sent to a marine-mammal expert to verify the detection. If it’s real, the system will send an alert to the U.S. Coast Guard’s Vessel Traffic Service, which can then share that information with ships in the region. UC Santa Barbara researchers and scientists at the Marine Mammal Center will use data from the system to study the whales. The data are also available in an online map.

The collaboration will soon add another camera installed on a ferry running between San Francisco and Vallejo to the north, providing a fuller picture of whales’ presence in the bay.

WhaleSpotter’s systems are already in use on vessels around the world, including eight container ships owned by Honolulu-based shipping company Matson. WhaleSpotter says the technology reduces the risk of ship strikes by 90 percent.

The San Francisco Bay system is the first to combine land-based and vessel-based monitors, and because it’s continuously monitoring one busy region during migration season—rather than looking for whales while crossing oceans—it’s already made an astonishing number of detections. As of 19 May, the system had been in operation for about a week and a half, and had already logged 6,600 whale detections. The scientists believe those may just be from a few whales hanging out in the bay in front of the cameras.

The camera system is good at detecting whales even before they’re visible to humans with binoculars—but without human intervention, it is still prone to false positives. A 2020 study using infrared cameras to detect marine mammals in the Atlantic Ocean off the shore of Canada found a high rate of false positives, mostly due to sea birds. So human verification is still necessary: If the system sends a warning when there is no whale, captains won’t take the information seriously in the future, says WhaleSpotter CEO Shawn Henry.

Henry says human verifications are being fed back into the algorithm to improve it. The system is already capable of determining if it’s detecting the same whale taking another breath, so similar detections in rapid succession are not sent to human experts for verification, says Henry. He hopes the company will be able to improve the system further to eliminate the need for human verification. “I like the AI—it doesn’t get tired like humans,” says Henry. “We want to rely on AI as much as possible.”

“Social engineering” sounds like something out of a conspiracy thriller, charged with totalitarian control and fringe paranoia. More mundanely, it’s come to be associated with phishing and other scams, in which fraudsters manipulate people into disclosing personal information.

Yet the concept is older and more benign: it is the deliberate shaping of human behavior, often at scale. It predates silicon—and became pervasive, and ungoverned, especially once its practitioners learned to hide it. Authoritarian regimes and more recently scammers and big companies have profited from it. To defend ourselves from bad actors, and to benefit from social engineering’s good side, we need to reclaim the name, and govern it prudently.

The roots of engineering

In 1894, Dutch entrepreneur Jacques van Marken urged companies to hire “social engineers” to manage human systems such as insurance, education, and profit sharing for workers as carefully as they did mechanical ones. Fifteen years later, reformer William H. Tolman published Social Engineering, describing how U.S. industrialists optimized workers’ conditions alongside manufacturing methods. If industrialists could shape steel and electricity on demand, why not society itself?

By the 1920s, that confidence had spread. The architect Le Corbusier declared that dwellings were “machines for living in,” imagining cities as orderly lattices where people moved like parts on a conveyor belt. Civilization would run like a Swiss watch.

The idea soon darkened. Authoritarian regimes pushed it to extremes, promising to fashion “the New Man.” In Nazi Germany, engineer Fritz Todt founded Organization Todt, a vast state engineering enterprise that emerged from the autobahn highway system and later operated concentration camps using slave labor.

In the Soviet Union, leaders adopted U.S. scientific management techniques to plan factory-worker movements and classify populations through centralized records, feeding both rapid industrialization drives and the gulag system of forced labor. The same tools and managerial methods used to build highways and enact five-year plans worked for repression and mass control.

By the 1950s, “social engineering” had become a contaminated phrase. The revelations of Nazi and Soviet abuses, along with Cold War critiques of grand social planning turned the term from a progressive slogan into a warning label. Banishing the words pushed the practice underground, making it harder to recognize when it resurfaced in new forms—such as organizational psychology and systems management that still relied on classification and behavioral influence techniques but under softer, less loaded labels.

Social engineering’s more subtle spread

In the postwar years, the new social-engineering lexicon included “human factors” and “urban planning,” all promising integration rather than command. As computing advanced, the language shifted again: “customer journey mapping” to track interactions, “user experience” to script them. Engineering, which began as a means of reshaping physical space, set its sights on shaping behavior. Digital design features embedded in our smartphones now target our attention and desire.

Language helps conceal these modern forms of social engineering. “Data analytics” sounds neutral beside “surveillance.” “Personalization” flatters individuality while still sorting users into predictable categories. “Behavioral nudges” guide decisions without the sense of intrusion. We attach “social” as a favorable modifier to sciences, capital, and media, yet recoil when it meets “engineering.”

That discomfort is a clue. Engineering implies control, and control prompts us to ask who directs whom, toward what ends, and with whose permission.

Not all social engineering these days is hidden. Hackers don’t need to break a firewall if someone hands over their password. Romance scammers cultivate intimacy the way farmers cultivate crops. They succeed not through force but by exploiting trust. If even these obvious attacks work, the invisible kind, with roots in social engineering, are a shoo-in.

Most of the social engineering we encounter is proprietary and beyond our control. Firms build recommendation algorithms tuned to boost engagement and profit with no hearings or right of appeal. Browser and cookie defaults decide what data we surrender. A single autoplay toggle can cost users hours and build unhealthy habits. These are acts of engineering as deliberate as laying a road or redrawing an electoral district. They create a kind of curated itch by which boredom never settles, and satisfaction never arrives. The results are predictable—users click on targeted ads, make purchases, form habits, and lock in opinions.

Consent has transformed along with it. Once straightforward and revocable, it is now subtle and persistent, buried in defaults or opaque terms of service too quickly accepted. You remain free to opt out, much as you are free to refuse roads or electricity. Consent has become the preselected setting of modern life.

When social engineering operated more in the open, citizens could contest it, at least in societies with responsive government. Today’s invisible version diffuses accountability so thoroughly that scrutiny becomes hard to direct. Despite recent congressional hearings on social media’s impact on youth mental health and juries agreeing that firms are knowingly designing algorithms that cause harm, pinpointing responsibility remains elusive. When the mechanism is buried inside a system used by billions, we cannot easily point to a single decision-maker or trace the precise moment of manipulation.

Today’s social engineering is less overt and theatrical than its predecessors. Earlier versions arrived on public posters and loudspeakers for mass audiences. Today’s version is more intimate, delivered through personal devices and constant feeds tailored to the individual. The model succeeds because participation feels like freedom, not control.

Not all social engineering is dystopian. Well-kept parks foster community, accessible buildings extend dignity, vaccines and seatbelts save lives. Even in the digital realm, positive examples exist: browser extensions that automatically block hidden trackers, search engines that refuse to build personalized surveillance profiles, and decentralized social platforms that give users greater control over their own data and feeds.

The term “social engineering” still unsettles, though. But “asocial” engineering, which ignores human consequences entirely, is worse. Recognition of the human dimension to engineering is the beginning of repair. Only by seeing the machinery clearly and naming it honestly can we decide who engineers what and why. The machinery will not dismantle itself. Once named, it becomes subject to choice. That negotiation of purpose, power, and process are the defining political questions of any real democracy. We cannot ensure that social engineering serves and sustains society so long as we dodge the words.

Bees and other pollinating insects play vital roles in food webs and crop pollination, yet monitoring them has proved difficult. That’s why researchers have developed a radar system that could lead to a cost-effective, noninvasive way to track pollinators.

Traditionally, identifying pollinators has proven tricky and time-consuming, and typically requires capturing and killing insects to get a close look at them. To find a better way to monitor pollinators, scientists are developing vision systems that use machine learning to automatically classify insects.

However, these machine learning systems face a major limitation when acquiring usable images, because of issues such as variable lighting, poor weather, and cluttered backgrounds—not to mention that many insects can just fly away when approached.

That’s why researchers based in Europe instead analyzed radar scans of insects. It’s not a new idea—scientists have used radar for decades to study migratory insects. However, that research was mostly focused on insects flying in large numbers at high altitudes, instead of lone insects flying near the ground, as pollinators do when visiting flowers.

“Typically, the radar reflection from single insects is very weak,” says Adam Narbudowicz, an associate professor of space research and technology at the Technological University of Denmark. “It’s probably impossible to detect them just by looking at a single point in time.”

Instead, “we hoped to be able to detect insects by integrating signals over longer durations,” Narbudowicz explains. Specifically, they focused on how insect wingbeats generate micro-Doppler signatures—distinctive time-varying patterns in radar reflections that arise from tiny motions, like wobbles. Micro-Doppler signatures allow radar systems to identify more subtle distinctions between objects, which can help the system distinguish between birds and drones, for instance.

Millimeter-Wave Radar for Pollinators

The scientists opted for millimeter waves for their radar system, because those wavelengths better match insect sizes than other portions of the radio-frequency spectrum. Millimeter waves have also found use in recent generations of cellular networks.

Narbudowicz and his colleagues trained a machine learning model on five species of pollinator insects, including honeybees and common wasps, captured on the campus of Trinity College Dublin. Several members of each species were individually placed in small plastic cylinders on top of a millimeter-wave antenna, which recorded their radar signatures. The insects were then released.

“In the beginning, we really weren’t sure it would work, as the insects are really small and the micro-Doppler signals we worked with were very weak,” Narbudowicz says.

The scientists had their model analyze more than 70 different features of the radar reflections from the insects. These included not only wingbeat frequencies but also the speed at which insect wing movements changed and the strength of the reflections. The researchers detailed their findings on 28 April in the journal PNAS Nexus.

Tiny differences in radar reflections, called micro-Doppler signatures, can be enough to distinguish between different insect species.Linta Antony, Cian White, et al.

“It’s fascinating to see how different species use their wings in different ways, and also that this can be observable in radar signals,” Narbudowicz says. “When looking at raw signals, it’s difficult to capture all the subtle details, but with sufficient machine learning you can distinguish those.”

The model was able to classify the five kinds of insects to the species level with 85 percent accuracy. When it came to more broadly distinguishing between the four bee species and the one wasp species—two different families of insects—it was able to do so with 96 percent accuracy.

The researchers found that species-identification accuracy improved the longer the insects remained within the radar system’s beam—for instance, accuracy went from 75 percent for 0.1 seconds to 84 percent for 1 second. They suggest developing traplike structures that insects can fly inside while the system examines them, releasing them unharmed after the analysis is complete.

“The power levels we use are below the levels that could harm insects,” Narbudowicz says. Comparatively, “a traditional insect trap relies on drowning the insect in poisonous cyanide liquid.”

Although this research focused only on pollinators, the scientists note that it could also help track pests and invasive species. Narbudowicz and his colleagues now want to develop a portable, field-deployable version of their technology. Ultimately, the scientists would like to collect more insect radar signatures to develop a global database enabling the instant classification of any insect within the system’s range.

The database could also include environmental data such as temperature and humidity to see how such factors might affect wingbeat frequencies and other pollinator features. The researchers suggest this database could one day also help monitor shifts in behavior through unusual changes in wingbeat patterns.

New Zealand is a country famed for its dramatic landscapes, but its linguistic landscape is arguably just as interesting. Of its three official languages, only te reo Māori (the Māori language) could be described as indigenous. Though spoken fluently by just 4.3 percent of the population, national statistics show that about 30 percent of New Zealanders can speak more than a few words or phrases of the language.

But ask ChatGPT to write te reo Māori and it will oblige, fluently answering your questions in the standardized form of the language taught in schools and broadcast on national television. Claude and Perplexity can do the same. This impressive language performance is built on text and audio produced by Māori communities and academics, which was scraped and ingested without their permission, processed outside New Zealand, and returned to users through interfaces owned by large technology companies. For Māori, that is a problem.

“These companies overseas have the resources to produce AI models that work well,” says Te Taka Keegan, a professor at the University of Waikato and codirector of its Artificial Intelligence Institute. “But they scraped all of that data with no input from us, and we don’t own the output. Our language is the most important conveyor we have for our knowledge.…yet we see technology developed outside of Aotearoa [New Zealand] get more and more control over the transfer of that knowledge.”

Motivated by this need for “sovereign digital systems,” as Keegan calls it, he and Kingsley Eng, Keegan’s master’s student at the time, set out to develop a high-fidelity synthetic voice—a text-to-speech system, in other words—for a specific dialect of te reo Māori. Every technical decision Keegan and Eng made along the way was shaped by a foundational constraint typically ignored by the AI sector—that this synthetic voice, and everything used to build it, must remain owned by the people who speak that dialect. What they produced, they hope, offers a replicable blueprint for other minority language communities around the world.

Challenges in Māori AI Voice Models

AI voice models are predominantly built in English, so applying those models to other languages can lead to errors. Te reo Māori has some specific linguistic features, such as the importance of vowel length, that lead to additional challenges for AI voice systems.

As an example, the words for “cake” (keke), “armpit” (kēkē) and “to creak” (kekē) differ only by how long the vowel sounds are. Digraphs—two letters making one sound— are also common, and are pronounced differently than they are in English; “wh” is usually pronounced “f.” In the Māori language, inaccurate pronunciation changes the meanings of words.

In addition, te reo Māori is considered a low-resource language, because, compared with a language like English or Chinese, there’s relatively little potential training data in the form of text, datasets, or recorded speech available in digital formats. To address this problem, Keegan recruited Ngaringi Katipa—a translator, educator, and language mentor—to be the consenting human voice behind the tool.

“Our language is the most important conveyor we have for our knowledge.…yet we see technology developed outside of Aotearoa get more and more control over the transfer of that knowledge.” —Te Taka Keegan, University of Waikato

“We focused on our local dialect, Waikato-Maniapoto, because it’s in the dialects that you see the real beauty of language. They tie it to a specific place and sense of identity,” says Keegan.

“We initially just recorded Ngaringi reading passages from books, which gave us 4.5 hours of data,” says Eng, now a machine learning engineer at the precision toolmaker Extec. “Later, we expanded the dataset by recording from a comprehensive list of sentences and words—including very rare words—given to us by Te Taka’s brother Peter, who is a Māori linguistics expert.” Once cleaned and processed, the final tally was 7 hours and 45 minutes of recordings.

A Māori Text-to-Speech AI Model

Building a text-to-speech system generally takes one of two approaches to data input. The first is character-based, where raw letters are passed directly to the model. The second is phoneme-based, where text is first converted into a phonetic representation, or a description of how each word sounds, before training begins.

“We tried both, but the phoneme approach was far better,” says Eng. “Giving the model phoneme rules off the bat was like a head start.” Phonemes effectively tell the model what certain groups of letters sound like, “which lets you skip some of the learning,” he says. To provide the model with phoneme rules, the researchers used an open-source tool called eSpeak NG, which includes a beta Māori rule set that they adapted further.

Eng tested three open-source neural architectures—Matcha-TTS, Tacotron2, and Piper—to train and transform the recordings into a synthetic voice. Piper, which can run offline on a local machine, had the best results and was chosen for the final build.

Despite using under eight hours of good quality recordings—considerably less than the hundreds of hours typically suggested for training a text-to-speech model—the final AI voice was effective. The primary metric used in text-to-speech research is word error rate, in which a lower percentage indicates higher accuracy. Keegan and Eng’s AI voice achieved an error rate of 6.78 percent, considered “good” by current industry standards.

Throughout the development process, a professional Māori language evaluator assessed the voice, rating it in terms of its naturalness, pronunciation accuracy, and expressiveness.

The researchers also invited 68 fluent speakers of te reo Māori to listen to both human and synthesized audio, and asked them to identify which was which. The listeners correctly identified the voices 65 percent of the time. “We were happy with that because some of the listeners were family members of the speaker—they know her voice really well, but a few still got it wrong,” says Keegan.

Māori AI Sovereignty

While Google provided some funding to the Waikato team, Keegan says it came with no conditions attached and no ownership stake claimed. “They said, we’ve heard about your work with preserving languages, and we wanted to support you. Use the grant whatever way you want.” Ultimately, he says, it allowed them to fairly compensate Katipa for her work.

With the tool now ready for use, the question of ownership remains front of mind for Keegan. From a standard intellectual property perspective, the voice belongs to Katipa. From a Māori perspective, Keegan says, it belongs to the collective: “It’s a treasure that’s been handed down through her ancestors; and her role is to protect it for her children and her grandchildren.”

So rather than release the voice model publicly, Keegan is in discussion with the three iwi (tribes) that Katipa affiliates with—Waikato, Maniapoto, and Raukawa. “Guardianship of this needs to sit with them,” Keegan says, “rather than the university.”

To that end, Keegan found a Wellington-based company, Catalyst IT, that gifted website hosting and the computing power needed to run the voice model for a year.

Data sovereignty is a rapidly growing focus in indigenous AI communities. Te Hiku Media, a Māori media organization in New Zealand’s far north, developed an automatic speech-recognition system that achieves 92 percent accuracy for te reo Māori and 82 percent accuracy for bilingual speech. The organization released the model under a Kaitiakitanga license—a legal instrument stipulating that data can only be used for the benefit of the Māori people.

Elsewhere in the world, the Aina project at the Barcelona Supercomputing Center released Matxa, a multidialect Catalan text-to-speech system also built on open-source architectures. In Quebec, Michael Running Wolf leads the First Languages AI Reality (FLAIR) initiative, which is working to build speech-recognition models for Indigenous languages across North America.

Voice-driven technologies, such as virtual assistants, screen readers, navigation systems, and smart devices, are ubiquitous. For Keegan, these tools can either be a way to “sanitize and colonize our language” or a means to “empower my moko [grandchildren] with their traditional knowledge.” The difference, he says, comes from who develops and owns the technology. “I want my grandchildren and my great-grandchildren to access our knowledge through our own systems. This voice is the first step in achieving that.”

Longer term, his ambition is to use the same open-source, community-owned methodology to build full language models. “It won’t be a te reo Māori large language model,” he says. “It’ll be a Maniapoto large language model, a Tūhoe large language model, et cetera.” Each model would be owned by, and trained on the speech of, the people whose language it speaks.

While that’s a more significant engineering challenge than a text-to-speech system, the Waikato project demonstrates that the necessary infrastructure already exists—efficient training on minimal data, phoneme-based input, open-source tools, and a legal and governance framework for community ownership. “We’ve laid a template so that other iwi throughout the country can do the same thing,” says Keegan. “I am happy to help them do it.”

This story was updated on 21 May, 2026 to correct Te Taka Keegan’s position: He is a professor at the University of Waikato, not an associate professor.

When a group of academics started making open-source robotics hardware, a generation of roboticists got years of their lives back. Now, the bigger challenge is getting robots to think—and that’s starting to be open sourced too.

The shift is still early, but companies including Hugging Face, Nvidia, and Alibaba have all made significant bets on open-source robotics in the last two years, releasing tools and models aimed at the higher-level work of getting robots to reason, decide, and act.

The open source movement that accelerated other AI applications is now being applied to the problem of making robots smarter. If these attempts to bring AI to robotics with open-source platforms succeed, the barrier to building a capable robot could fall as fast as the barrier to building an AI application did.

The world ROS built

Open-source robotics software has been around since the mid-1990s, with early projects like Carnegie Mellon University’s Inter-Process Communication package and the Player Project in the early 2000s laying the groundwork. But these were often tied to specific research groups, and the field remained fragmented.

The Robot Operating System, ROS, changed that when it made its debut in 2007. By bundling tools and attracting more users, it became the de facto standard. The story of open-source robotics, in many ways, starts there.

Despite its name, ROS is not actually an operating system. Rather, it is a software framework that sits on top of Linux and handles robotic fundamentals like moving data between components, talking to hardware, building maps, planning paths, and supporting developer tools, such as data logging and visualization. Before ROS, every robotics team wrote that infrastructure themselves. It often took a year or two before a lab could get to the research it actually cared about.

Brian Gerkey, who helped build ROS in the mid-2000s, says he was drawn to the project because of how much open source had already changed the world, pointing out that nearly the entire internet is built on it.

“I’m a tool builder, and I like to share everything as openly as I possibly can, because I think that’s where we get the most impact out of what we build,” says Gerkey, board chair of Open Robotics and now CTO at Intrinsic, a robotics and AI unit of Google.

As it was developing, the AI community largely took the same approach, sharing research, models, and data openly, and the field accelerated faster than almost anyone predicted. Now some of those same advancements are arriving in robotics.

Open-source AI for robotics

Computer vision, once a hard problem, has advanced dramatically in just a few years, says Spencer Huang, Nvidia’s director of product for robotics. What once required significant expertise can now be done in a few lines of code. Simulation tools have become accurate enough to be useful for training, and access to the tooling that once required a specialized lab is now widely available, much of it open source.

“To get into robotics, you no longer need a Ph.D.,” he says. The result is a much larger pool of people who can contribute, and the field is starting to look less like a specialized discipline and more like a platform that anyone can build on.

Nvidia has built out an open-source robotics stack that covers the full development pipeline. Its Cosmos world models generate synthetic training data and simulate physical environments. Its GR00T models give robots the ability to reason through and execute complex tasks. And its Isaac frameworks handle the orchestration that ties training, simulation, and deployment together. Not everyone needs to train the robots from scratch, Huang says, and most people probably shouldn’t.

“If you gate pre-training, the field just never grows,” he says. “We should be able to provide a high-quality, state-of-the-art pre-trained model that anyone can go and take and fine tune for their own purposes.”

All of Nvidia’s open-source models live on Hugging Face, the open-source AI platform that has become the default place to share models and datasets. Hugging Face launched LeRobot, a community platform for robotics AI, in May 2024. Since its launch, the number of robotics datasets on the platform grew from 1,145 at the end of 2024 to more than 58,000 today, making it the single largest dataset category on the hub.

Hugging Face has also moved into hardware, acquiring robotics company Pollen Robotics. The acquisition came from a realization that software alone was not enough, according to Clement Delangue, Hugging Face’s CEO. The goal, as with the software, was to bring more people in.

The contributors to LeRobot include the biggest names in the industry, academic labs, and hobbyists building robots in their spare time. For instance, earlier this year, Alibaba released RynnBrain, an open-source foundation model for physical AI that the company claims outperforms comparable offerings from Google and Nvidia on benchmarks. That diversity of projects, Delangue says, is important.

“It is not just one model or one dataset or one hardware,” he says. “It is a lot of small contributions that everyone can be part of.”

Commercial incentives muddle the field

The stakes, Delangue says, go beyond convenience. A world where only a few proprietary systems control the robots in people’s homes is a concerning one. “Having robots at home that you don’t really understand, that you don’t really control, that a few people in Silicon Valley control is a scary thought,” he says. “Open source gives an alternative path.”

But getting there is not straightforward. The open sourcing happening now looks different from what produced ROS, which emerged largely from academics pooling their work with no commercial stake in the outcome. The biggest contributors today are companies with clear business reasons to want more people building on their platforms. That’s not necessarily a bad thing, says Bill Smart, a professor at Oregon State University, in Corvallis, who was part of the early open-source robotics community. But the incentives are worth being aware of.

He also worries that the lowered barrier to entry has a downside. Researchers coming from AI without a robotics background are sometimes solving problems the field already solved. A newcomer might spend a week training a neural network to move a robot’s hand from one point to another, unaware that the same task can be accomplished with a few lines of code using decades-old techniques. The incentives are not always pointing in the same direction as the progress.

Smart is not without hope though. Whatever the motives behind the open sourcing, he says, the effect is real. More people are in the field than ever before, the tools are genuinely easier to use, and the community is bigger and more diverse than anything that existed when ROS was getting started.

“Anyone can make a robot move now,” he says. “As an old tech guy, that makes me happy and sad, because I’m no longer special.”

A field technician on a wind turbine, harness clipped, both hands on a wrench, needs to send a command to the diagnostic device hanging at her belt. A logistics worker on a loading dock, gloves on, eyes on the pallet, needs to redirect a connected lift. A person using an assistive mobility device on a crowded street wants to nudge it forward without taking out a phone or speaking aloud. None of these moments call for a smarter robot. They call for a smarter way to be heard by the machines that already exist.

The industry has been building from one side

The past three years of Physical AI have been a story of remarkable progress on the robot side of the loop. Companies like Boston Dynamics, Figure, and Unitree have advanced actuators, locomotion, and dexterity to a level that would have seemed implausible a decade ago. Google DeepMind’s Gemini Robotics has redefined what vision-language-action models can do in unstructured settings. The trajectory of the hardware and the foundation models is real, and it is accelerating.

But there is another side to this loop, and it has been treated as a solved problem for too long. The interface between humans and machines has defaulted, for 40 years, to three input modalities: screens, buttons, and voice. Each of those assumes the user can stop, look down, and translate intent into structured commands. That assumption breaks the moment the work moves into a real environment. On a turbine. On a dock. On a sidewalk. In any setting where hands are occupied, eyes are committed, or speaking is impractical, the conventional interface stack quietly fails.

Spatial Intent Fusion is the simultaneous processing of three streams of human-centered information, namely spatial position, visual context, and gestural intent: Your body is the interface.

The bottleneck on the human side of the loop is becoming as important as the one on the machine side. And solving it requires a different question. Not how do we make the robot more capable, but how do we let the human participate in the computing system as naturally as the robot already does.

Wetour Robotics’ bet: put the human back into the computing loop

Wetour Robotics is betting that the next architectural leap in Physical AI is not about making the robot more capable. It is about making the human a first-class node in the computing network, with the same kind of low-latency, high-fidelity participation that connected devices already enjoy.

Wetour Robotics’ engineers frame the problem this way: a wristband that recognizes a gesture is not enough. A camera that recognizes a scene is not enough. The information a human carries about what they are about to do is distributed across multiple channels, including where their body is in space, what their eyes are attending to, and what their muscles are preparing to do, and any single channel observed in isolation is ambiguous. Reconstructing intent reliably means fusing those channels at the operating system level, with latency low enough that the loop feels closed rather than mediated.

This approach has a name. Wetour Robotics calls it Spatial Intent Fusion: the simultaneous processing of three streams of human-centered information, namely spatial position, visual context, and gestural intent, fused into a single real-time command for any connected physical device. It is the technical implementation behind a simpler positioning statement the company uses externally: your body is the interface.

Orchestra is a portable intelligent hub running the operating system that handles sensor fusion, intent inference, command translation, and safety arbitration. The reference compute platform is NVIDIA Jetson Orin Nano Super, which provides enough on-device inference capacity to keep the entire control loop at the edge, with no cloud dependency on the critical path. Wetour Robotics

The architecture: three layers, four engines, one loop

Orchestra is not a single device but a layered platform, designed from the start to be sensor-flexible and actuator-agnostic. The architecture decomposes into three perception layers and four coordination engines.

Orchestra itself is the local compute and orchestration core: a portable intelligent hub running the operating system that handles sensor fusion, intent inference, command translation, and safety arbitration. The reference compute platform is NVIDIA Jetson Orin Nano Super, which provides enough on-device inference capacity to keep the entire control loop at the edge, with no cloud dependency on the critical path. Edge inference is non-negotiable for this application. Full-chain latency from biosignal acquisition to actuator command is held under 100 milliseconds, the envelope inside which closed-loop control feels natural rather than laggy.

VisionLink handles visual and spatial perception. Cameras feed into vision models that identify objects, estimate distances, and track environmental context. VisionLink is designed not as a passive recognition layer but as a real-time command generator: its outputs feed directly into Orchestra OS to be fused with biosignal data.

Conductor is the biosignal pipeline. It ingests raw surface electromyographic (sEMG) data from a wrist-worn device, classifies temporal patterns into discrete gestures or continuous control signals, and outputs actuator commands. The technically interesting property of sEMG for this use case is that the signal precedes visible motion. Motor unit action potentials appear at the skin surface roughly 50 to 80 milliseconds before a finger completes the corresponding gesture. Wetour Robotics calls this property pre-motion intent sensing, and it is what allows Orchestra to anticipate user intent rather than react to it.

On top of the three perception layers, Orchestra OS runs four coordination engines. The Perception Engine ingests and normalizes raw sensor streams. The Intent Engine performs Spatial Intent Fusion across modalities, resolving what the user is trying to do given where they are, what they are looking at, and what their hand is signaling. The Orchestration Engine translates intent into device-specific command sequences for any connected actuator. The Safety Engine arbitrates conflicting commands, enforces operational envelopes, and gates execution against runtime safety conditions.

Wetour Robotics

The trade-offs we’re honest about

No system that bridges the human body and the digital world is finished. Three engineering challenges remain open, and the company addresses each with a deliberate trade-off rather than a claim of having fully solved it.

Baseline stability of sEMG under motion. In a stationary user, continuous gesture recognition from sEMG is reliable. Once the user is walking, climbing, or otherwise moving, motion artifacts and electrode drift degrade the signal in ways that are difficult to fully compensate for. Rather than overpromise on continuous control in dynamic settings, Orchestra defaults to a smaller set of robust discrete gestures in complex operating environments, and reserves continuous control modes for contexts where the signal-to-noise ratio supports them.

Miniaturization of edge AI compute. Running the Orchestra control loop entirely at the edge requires real on-device inference, which has historically meant trading off between compute capacity, battery life, and form factor. Wetour Robotics’ approach has been a compact carrier board paired with a thermal design and a battery module sized for all-day wearability. The result is a hub that travels with the user rather than tethering them to a desk, and that performs the full perception-to-actuation loop without offloading to the cloud.

Heterogeneity of third-party device protocols. The actuator side of the loop is a fragmented landscape. Different manufacturers expose different command interfaces, different communication stacks, and different safety conventions, and a Physical AI operating system has to integrate with all of them. Wetour Robotics uses an AI-agent layer to negotiate connection and protocol translation adaptively, so that Orchestra OS can ingest data from a wide range of devices, run them through neural network models that infer human intent, and emit the right command on the right protocol for the device on the other end.

Why this matters, and why it helps the rest of the field

The history of computing is a history of interface revolutions. Command lines gave way to graphical user interfaces, which gave way to touch, which gave way to voice. Each transition expanded who could participate in the system and what they could do with it. The next transition is not about a new screen or a new microphone. It is about treating the human body itself as a participant in the computing network, capable of contributing intent at the same speed and fidelity that any other connected node can.

The history of computing is a history of interface revolutions. The next transition is not about a new screen or a new microphone — it is about treating the human body itself as a participant in the computing network.

This path is not a competitor to the work being done on humanoid robots, foundation models for embodied AI, and dexterous manipulation. It is the missing complement to that work. The hardest open problem for humanoid systems is the data: every natural interaction between a human and the physical world is a potential training signal, and most of those interactions are currently invisible to any computing system. As more humans become first-class nodes in the loop, those interactions become observable, structured, and ultimately useful for training the next generation of embodied AI, including the humanoid robots being developed today.

In other words: putting the human back into the computing loop is not just about better interfaces for individual users. It is about generating the kind of grounded, in-the-wild human-machine interaction data that the broader Physical AI ecosystem will need to keep advancing. The robot side and the human side of the loop are not two competing futures. They are two halves of the same one.

That is what Wetour Robotics means when it says: Your body is the interface.

Melbourne’s reputation as a global events city, from the Australian Open tennis and Formula 1 Australian Grand Prix to hosting NFL regular season games, now intersects with a different form of scale: large-scale compute, data-intensive research, and advanced engineering. Long recognized for delivering complex international events, the city is applying the same organisational capability to the infrastructure that underpins modern AI research, positioning Melbourne at the convergence of global convening and high-performance digital systems.

Consistently ranked among the world’s most livable cities, Melbourne was named Time Out’s Best City in the World in 2026, the first Australian city to hold the title.

Australia’s artificial intelligence (AI) ecosystem is entering a new phase, defined less by isolated initiatives and more by the convergence of compute infrastructure, research intensity and international collaboration. Melbourne sits at this intersection.

Melbourne’s trajectory highlights what enables research at scale: access to frontier-grade compute, proximity to industry-ready infrastructure, and repeated opportunities for global research communities to convene.

Sovereign AI compute, expanding hyperscale data center campuses and a growing pipeline of international research-led conferences are reshaping the city’s research landscape. Together, these elements position Melbourne as a focal point for applied AI research, advanced engineering and data-intensive science.

The growing global influence of AI engineering, underscored by NVIDIA CEO Jensen Huang receiving the 2026 IEEE Medal of Honor, reflects the scale of this shift. In Melbourne, these factors form a reinforcing research flywheel linking infrastructure, discovery and collaboration.

Rather than focusing on startup density or short-term commercial output, Melbourne’s trajectory highlights what enables research at scale: access to frontier-grade compute, proximity to industry-ready infrastructure, and repeated opportunities for global research communities to convene.

Sovereign AI foundations

The most recent cornerstone of Melbourne’s AI capability is MAVERIC (Monash AdVanced Environment for Research and Intelligent Computing), Australia’s largest university-based AI supercomputer. Built and deployed by Monash University in partnership with NVIDIA, Dell Technologies, and CDC Data Centres, MAVERIC has been engineered specifically for large scale AI and data intensive science, with medical research representing a key priority. Indeed, in these regards MAVERIC has been designed to function as a Next Generation Trusted Research Environment thus ensuring that it is state-of-the-art and provides a safe and secure framework for the analysis of large sensitive datasets.

Designed to support research projects including cancer and neurodegenerative disease detection, clinical trial analysis and drug discovery through to materials science and engineering, MAVERIC enables Australian researchers to train and evaluate large models domestically while keeping highly sensitive datasets secure and under national jurisdiction. This sovereign design is particularly relevant in fields such as medical research where privacy, regulation or intellectual property constraints limit the use of offshore cloud resources.

Technically, the system reflects the latest shifts in high performance AI architecture. Built on NVIDIA GB200 NVL72 platforms and integrated using Dell’s rack scale infrastructure, MAVERIC employs closed loop liquid cooling to reduce water consumption compared with conventional air-cooled systems, aligning large scale compute growth with sustainability objectives while supporting high density, high throughput workloads.

Professor James Whisstock, Deputy Dean Research of Monash’s Faculty of Medicine, Nursing, and Health Sciences commented, “MAVERIC provides a huge leap forward in our compute capability that will revolutionize our researchers’ ability to address the most challenging and important research questions across the fields of medical research, information technology, and STEM disciplines. It will seed wonderful new cross-disciplinary collaborations, underpin the work of our best and brightest young researchers and will allow our scientists to continue to make major discoveries that positively impact the Australian and global population more broadly.”

Monash University frames MAVERIC not as a standalone asset, but as part of the national research infrastructure, intended to strengthen collaboration across academia, healthcare, government and industry. This approach positions Melbourne at the forefront of sovereign AI enabled research in the region.

Data center scale as research infrastructure

The infrastructure demands of modern AI research extend well beyond individual systems. Melbourne’s expanding data center footprint now supports hyperscale compute, applied AI deployment and large-scale research workloads simultaneously.

In February 2026, CDC Data Centres opened its first Melbourne campus in Brooklyn, with two live facilities and a third in planning. Combined with CDC’s Laverton campus, Melbourne is projected to host more than 800 megawatts of sovereign digital capacity, critical for AI workloads requiring sustained access to high-density power, cooling and secure environments.

Parallel investment is underway in Fishermans Bend, where NEXTDC is developing a AUD $2 billion AI and digital infrastructure hub adjacent to the Innovation Precinct. Planned facilities include an AI Factory, a Mission Critical Operations Center and a Technology Center of Excellence, enabling sovereign AI, high-performance computing and cross-sector collaboration across health, defence and finance.

Melbourne hosts Australia’s largest cluster of AI firms, with 188 companies, and more than 40 data centers currently operate across Victoria. The Victorian Government has complemented this growth with an initial AUD $5.5 million investment in the Sustainable Data Center Action Plan.

Together, these developments reinforce Melbourne’s role as a national and increasingly global hub for high-performance AI infrastructure as model complexity and infrastructure dependency continue to accelerate.

Applied AI research at scale

Melbourne’s research strength is underpinned by a dense university network with deep capability across AI, data science and engineering. Institutions including Monash University, the University of Melbourne, Deakin University, La Trobe University, RMIT University and Swinburne University of Technology collectively support research across machine learning, robotics, human-computer interaction, extended reality and advanced manufacturing.

This concentration fosters applied collaboration where AI intersects with medicine, sustainability, cognitive systems and immersive technologies. For visiting researchers, it provides access not only to academic expertise but also to live infrastructure environments where research can be tested and validated, reinforcing Melbourne’s position as one of the Asia-Pacific’s most integrated AI research ecosystems.

Conferences as research accelerators

Melbourne’s selection as host city for a growing number of international technology conferences reflects the convergence of research capability and infrastructure maturity.

In September 2026, Data Center World Australia and The AI Summit Australia will be co-located at the Melbourne Convention and Exhibition Center, bringing together global leaders across AI, digital infrastructure and enterprise technology. The pairing highlights a broader reality: advances in AI are inseparable from the infrastructure that enables them.

Melbourne’s expanding data center footprint now supports hyperscale compute, applied AI deployment and large-scale research workloads simultaneously.

Research-led conferences are also expanding Melbourne’s global footprint. ICONIP 2026, hosted by Deakin University, will bring up to 700 researchers in neural networks and machine learning, followed in 2027 by IEEE VR, the leading conference on virtual reality and 3D user interfaces, attracting up to 1,000 delegates.

In this context, conferences function not simply as events, but as infrastructure for knowledge transfer, supporting standards exchange, collaboration and system-level learning at global scale.

A global platform for advancing research

Sovereign compute, data center scale and a strong conference pipeline create a reinforcing cycle, enabling researchers to engage directly with infrastructure and industry well beyond the event itself.

By closing the gap between theory and deployment, Melbourne supports deeper technical exchange and more enduring global research networks.

This role was recognized in 2025 when the IEEE awarded Melbourne Convention Bureau the 2025 Organisational Supporting Friend of IEEE Member and Geographic Activities (MGA) — the first convention bureau in the Asia Pacific region to receive the acknowledgement as a result of the longstanding partnership with the IEEE Victorian Section.

As AI research becomes increasingly dependent on infrastructure scale, sovereign capability, and global collaboration, Melbourne is moving beyond hosting conversations to actively enabling the systems that advance AI and data‑driven research at global scale.

AI-powered voice and audio tools are becoming increasingly embedded in daily life, from digital assistants to smart speakers and customer service bots.

Advances in large audio-language models (LALMs), which can both analyze and generate audio, now make it possible to control devices using voice commands, transcribe meetings automatically, or identify a song playing in the background. These models are also increasingly equipped with the ability to communicate with external services and operate other applications and tools.

But these tools can be “hijacked” through imperceptible sounds embedded in audio, forcing them to execute unauthorized commands without a user’s knowledge. New research due to be presented at the IEEE Symposium on Security and Privacy in San Francisco next week shows that a modified audio clip undetectable by human ears can manipulate a model’s behavior with an average success rate of 79 to 96 percent. The clips are designed to work regardless of what instructions the user provides alongside the audio, meaning they can be reused to attack the same model multiple times.

The authors tested the approach against 13 leading open models, including commercial AI voice services from Microsoft and Mistral, and showed they could coax models into conducting sensitive web searches, downloading files from attacker-controlled sources, and sending emails containing user data.

“It takes just half an hour to train this signal, and then, because this signal is context-agnostic, you can use it to attack the target model whenever you want, no matter what the user says,” says lead author Meng Chen, a Ph.D. student at Zhejiang University in China.

How adversarial audio injects attacks

The research builds on years of work into “adversarial audio examples”—audio manipulated to deceive machine learning models. Previous work focused primarily on how these files could induce incorrect predictions in models that perform one-way tasks like speech recognition or audio classification.

What singles out this new work, Chen says, is that it targets generative models capable of producing responses and taking actions. Their technique, dubbed AudioHijack, exploits a critical security flaw in LALM design: Because these models can receive instructions in audio format, malicious instructions can be hidden in manipulated clips to elicit a wide range of undesirable behaviors.

Many previous attacks on generative models required the attacker to have complete control over both the final audio input and original instructions given to the model, essentially acting as the user. Here, the attacker manipulates only the audio data being processed by the model, which makes it possible to attack a model while it’s being used by someone else.

Real-world examples include hiding malicious instructions in online videos, music clips, or voice notes that users query an AI about, or broadcasting malicious audio on a Zoom call that is then uploaded to AI transcription services. Chen says the team’s more recent, unpublished studies have also demonstrated the ability to inject their malicious audio into a live voice chat with an AI in real time.

The researchers used a tried-and-tested approach to creating adversarial examples. This involves adjusting the numerical values that represent the waveform in the digital audio file in ways that don’t significantly alter how it sounds, but elicit unintended behaviors in the model when it processes the data. The technique relies on an optimization algorithm that repeatedly tweaks an audio clip, measures the impact on the model’s response, and then uses this signal to further adjust the audio until the model does what the attacker wants.

Targeting generative AI audio models

Applying this to generative models poses a major challenge. Older AI provides fine-grained feedback on how tiny changes to raw audio affect responses. Generative models, however, break audio into chunks and assign them to numerical representations called “tokens,” mapping each snippet to the closest match.

This coarser process makes it harder to tell whether a manipulation has moved the model closer to the desired behavior, confounding the optimization algorithm. So Chen and colleagues devised a way to approximate the fine-grained feedback required for the optimization algorithm to adjust the manipulation.

This required full access to the model, restricting the researchers to open models with publicly available weights. They found, however, that attacks developed for open models transferred to commercial models from Microsoft and Mistral that share the same underlying architecture.

In response to a request for comment, a Microsoft spokesperson said, “We appreciate the researchers’ work to advance understanding of this type of technique. This study evaluates model resilience through controlled, direct interactions with the model itself, which helps inform our approach to building model resiliency. In practice, AI models are often integrated into user applications, and we offer developers tools and guidance they can use to implement additional layers of protection that help safeguard users.”

Mistral did not reply to a request for comment by the time of publication.

Making AudioHijack more effective

Attacking proprietary closed models from companies like OpenAI and Anthropic is much harder, Chen says, given limited public information about their architectures. But these models often use open-source components—such as pre-trained audio encoders—that can be targeted similarly, something the team is currently investigating.

To ensure the attack works, regardless of what instructions the user provides alongside the malicious audio clip, the researchers paired the audio clip with different user instructions on each round of the optimization process.

They also found a way to commandeer the model’s attention mechanism, the component that helps the model identify the parts of the audio that are relevant to the task it’s been set to perform. The researchers introduced a measure of how much attention the model pays to the adversarial audio versus the user’s own instructions at each step, feeding this into the optimization process to produce samples that draw more attention from the model.

To make the manipulations harder to detect by a human listener, the researchers used a technique they had developed previously, which makes changes to the audio sound like natural reverberation. This is harder for humans to detect than earlier approaches that added noise to the original signal.

Testing on today’s AI audio models

The team demonstrated six categories of attack: making the model claim it cannot process audio, refusing user requests, responding with false information, inserting malicious links, altering the model’s persona, and triggering unauthorized tool use.

And worryingly, the approach proved resistant to common defenses. Providing models with examples of malicious instructions to watch out for reduced attack success by just 7 percent, while asking the model to reflect on whether its response matched the user’s instructions caught only 28 percent of attacks.

“These single-point defenses struggle to resist our attack because we found it’s very hard for these models to distinguish the normal user intent and our adversary attack,” Chen says.

The only effective tactic was monitoring the models’ internal attention mechanisms to detect AudioHijack’s attempts to steer attention toward the malicious audio. However, the researchers showed that an attacker aware of this defense can dial back the attention manipulation at the expense of a small reduction in attack success.

In the real world, this kind of audio attack will face additional challenges such as compression and various post-processing mechanisms that could degrade signals, says Eugene Bagdasarian, an assistant professor of computer science at the University of Massachusetts Amherst. But he says that multi-modal attacks on AI models remain an essentially unsolved problem.

“With text data we can understand that something is wrong (special characters, suspicious sentences, etc.). Audio modality is really challenging to comprehend because of how limited our hearing is,” he writes in an email.

Electronic rings wirelessly connected to an AI system are capable of translating multiple sign languages into text, a new study finds.

“I believe this is an important step toward making sign language translation systems more practical, lightweight, and usable in real-world environments,” says Ki Jun Yu, an associate professor of electrical and electronic engineering at Yonsei University in Seoul, Korea.

More than 300 different sign languages are used worldwide, and many research projects are developing translation devices for communicating with people who do not know a sign language. However, these projects have faced many setbacks.

For example, some projects used cameras and computer vision algorithms to recognize hand gestures. But these were typically limited to controlled settings with fixed cameras and were sensitive to lighting variations and other forms of interference.

Other devices relied on wearable sensors that detected either hand motions or electrical signals linked with muscle activity. However, a common kind of wearable sensor, smart gloves, trapped heat and moisture, making prolonged use uncomfortable. And their fixed sensors failed to account for individual variations in hand size, finger length, and joint positions, reducing their accuracy. In addition, wearable sensors often required hooking up to computers using wires, hampering hand movements. Although some wearable sensors ultimately transmitted their data wirelessly to an external processor, these still typically connected to the same single transmitter using wires.

Better living through wireless

Now, scientists have developed a set of electronic rings that each transmit their motion wirelessly to a processing device. Using rings instead of gloves permitted flexible positioning of sensors to help account for variations in people’s hands. The wireless connections allow unrestricted hand motions.

“Bluetooth Low Energy SoCs [systems-on-chips] have reached a point where an entire wireless communication stack, power management circuit, and sensing module can fit on a flexible substrate small enough to wear as a ring,” Yu says.

In the new study, the researchers examined how much each finger contributed to hand signs, discovering that seven fingers played major roles. As such, their system only employed seven rings to reduce the amount of hardware needed.

Each ring used accelerometers as inertial sensors. These could detect both stationary postures and hand movements to help capture the full complexity of sign languages, which often involve transitions between static and dynamic components. In addition, the scientists wanted to avoid relying on bioelectric signals, which are highly specific to each person and require extensive calibration for each user.

One challenge in developing these rings was mechanical reliability. Initially, the scientists used straight copper interconnects, which nearly broke under repeated bending. They switched to interconnects with serpentine patterns that withstand repeated flexing.

One AI to unite the rings

The researchers also developed a deep-learning system to recognize signs from hand movements. It could identify signs not just from the two people who were used to train the system, but also from five people who did not take part in the training phase. This suggests the new system could prove of general use without requiring laborious adaptation for each user.

In experiments with the five people who did not help train the system, the new system could recognize 100 common American Sign Language and 100 common International Sign Language words with 88.3 and 88.5 percent accuracy, respectively. In contrast, most previous attempts at sign language translation systems were limited to vocabularies of fewer than 50 words.

“Two hundred words is a meaningful advance over prior wireless systems, but it is still a small fraction of a full sign language lexicon, which can contain thousands of signs,” cautions Dosik Hwang, a professor of electrical and electronic engineering at Yonsei University. “I want to be careful not to overstate what the current system can do in open-vocabulary, real-world conversation.”

The new system was not just capable of recognizing isolated words, but of translating entire sentences from continuous signing. The scientists suggest this could help support real-time interpretation.

In the long term, “our goal is to make the system work with everyday devices such as smartphones without requiring specialized external equipment,” Yu says. “The rings could wirelessly transmit sign language signals to a mobile device, where they would be automatically translated and displayed in real time. This would make the technology more portable, accessible, and practical for daily communication.”

However, “the most important caution is this—our system translates hand motion into text,” Hwang says. “It does not yet capture facial grammar, mouthing, body posture, or spatial syntax, all of which are grammatically meaningful in sign languages.” A future challenge lies in incorporating those “into a seamless, low-power architecture that maintains the unobtrusive nature of our current design,” Yu adds.

The scientists next aim to train the system with more people, larger vocabularies, and more signing styles and regional dialects, Yu says. “Given our institutional roots, Korean Sign Language is a natural next step,” he adds.

The researchers also hope to make their rings wearable all day, up from nearly 12 hours, through further miniaturization and power optimization, Yu says. “A key priority is migrating the processing pipeline from external hardware [like a laptop] to on-device edge computing [like a mobile phone]. This transition is essential not only for true mobility but also for ensuring user privacy and reducing latency in natural conversation.”

Hwang and colleagues plan to partner with deaf community organizations to develop their devices. “We believe the technology will be significantly improved both in its functional performance and its social integration by including those who will actually use it,” he says.

Beyond sign language translation, these new rings might find use in other gesture-driven applications, Hwang says. “We see immediate potential for this technology in hand rehabilitation monitoring, fine-motor assessment for neurological conditions, and even immersive virtual reality and augmented reality interfaces,” he explains. “By proving its efficacy in the complex domain of sign language, we have essentially stress tested the system for a wide array of future biomedical and interactive applications.”

The scientists detailed their findings on 1 May in the journal Science Advances.

A hydrated leaf is a healthy leaf. That’s true for the leaves of crop plants in a farmer’s field and for the leaves of trees in an area vulnerable to forest fires.

But the traditional techniques to monitor leaf hydration require cutting them from their plants, which is time-consuming and cannot give live measurements. That’s why many researchers are building sensors that measure a plant’s health in real time.

Now, researchers in Texas have developed a graphene “tattoo” that can be stuck directly onto a leaf to provide real-time moisture readings. The researchers also believe it could one day be the building block for a new kind of plant monitoring, by turning the patches into a neural network that computes on the plants themselves.

“Not only are we just sensing the moisture level, but we can have that sensor act as this artificial synapse, which then we can put into a neural network,” says Jean Anne Incorvia, an associate professor of electrical and computer engineering at the University of Texas at Austin. Incorvia and colleagues (including her graduate student Utkarsh Misra) published their work in Nano Letters in February.

A forest of the future, Incorvia and colleagues think, might hold a whole grove of sensors networked to gauge the risk of fire or drought in real time.

A Graphene Leaf “Tattoo” as a Moisture Sensor

The sensor is a graphene patch that can be pasted onto the leaf of a plant (the researchers used Monstera) like a stick-on tattoo. It’s functionally a sort of three-terminal transistor, with a graphene channel, gold strips as its electrodes, and the leaf itself as its dielectric insulator.

The sensor can gauge a leaf’s hydration level in real time by sending an electric pulse into the leaf, which moves around ions within the leaf and changes the graphene’s conductance. The magnitudes of these conductance changes depend on moisture inside the leaf, so the researchers can read out a leaf’s hydration without a need for external processing.

Graphene is a good material for a leaf tattoo. It’s nearly transparent, so it won’t block light and disrupt photosynthesis. It can stretch and squeeze as the leaf grows, shrinks, or twists.

This isn’t the first graphene sensor of its kind, but real-time hydration sensors aren’t common in the field. The researchers hope this new sensor can change that by fitting into a neural network, because it also acts like a synapse in a brain.

In particular, just as neural activity can strengthen or weaken a synapse, the researchers could use particular electric pulses to slightly adjust their sensor’s conductance up or down. Moreover, after a pulse ended, the sensor returned to its original conductance slowly, over about 90 seconds. In that time, their sensor could act as a sort of short-term memory.

The researchers imagine they could one day use such artificial synaptic qualities to tune and store a neural network’s weights.

Neuromorphic Plant Computing

For several years, Incorvia’s group has designed non-leaf-based devices for these kinds of neuromorphic computing. They’ve typically crafted transistors with graphene and Nafion, a polymer that’s a good proton conductor. With a current pulse, the transistors can control how many protons migrate inside the Nafion—and, in turn, how many electrons cross the graphene channel. Thus, their devices can take on different weights inside a network.

Maya Borowicz, an undergraduate visiting Incorvia’s lab for one summer, noted that a plant leaf could conduct protons too. Why not swap out the Nafion, Borowicz suggested, to make a device that’s part-leaf?

“We actually did it a few years ago, and it worked, and we were like, ‘This is cool,’” Incorvia says. At first, they weren’t sure how to use it. “We kind of just tabled it.”

Months passed before Incorvia had an encounter with Ashley Matheny, a geologist working on better ways to monitor moisture levels in forests. “Through talking to her, I realized…there actually is a good value proposition for needing these types of sensors,” Incorvia says.

Now, in their work, Incorvia and colleagues demonstrated one possible future. They trained a relatively simple neural network called a single-layer perceptron to examine their sensor’s readings and classify the leaf as hydrated, normal, or in drought conditions.

This model ran on external hardware, but the researchers hope the sensor’s quality as an artificial synapse can help it run similar networks on plants themselves.

Incorvia envisions a network that ties leaf-mounted sensors together with others in soil and tree sap. Farmers could use it to monitor their fields in the face of climate change-induced drought; forest rangers could receive live updates on the numbers of dry leaves that could kindle a fire.

“You could imagine a neural network of trees, where we could be sensing across the forest,” Incorvia says.

At pivotal moments in history, progress has required more than individual brilliance. The most consequential breakthroughs — such as those achieved under the Human Genome Project — required a new operating paradigm: Concentrate the world’s best talent around a single mission, establish a common platform, share critical infrastructure, and collapse feedback loops. When stakes are high and timelines are compressed, sequential and siloed innovation simply cannot keep pace.

Today’s AI era is creating an engineering race with similar demands. Every company is pushing to deliver higher-performance AI systems, faster. But performance is no longer defined by compute alone. AI workloads are increasingly dominated by the movement of data: In many cases, moving bits consumes as much — or more — energy than compute itself. As a result, reducing energy per bit can extend system‑level performance alongside gains in peak compute.

The path to energy‑efficient AI therefore runs through system‑level engineering, spanning three tightly interconnected domains:

• Logic, where performance per watt depends on efficient transistor switching, low‑loss power, and signal delivery through dense wiring stacks.
• Memory, where surging bandwidth and capacity demands expose the memory wall, with processor capability advancing faster than memory access.
• Advanced packaging, where 3D integration, chiplet architectures, and high‑density interconnects bring compute and memory closer together — enabling system designs monolithic scaling can no longer sustain.

These domains can no longer be optimized independently. Gains in logic efficiency stall without sufficient memory bandwidth. Advances in memory bandwidth fall short if packaging cannot deliver proximity within thermal and mechanical constraints. Packaging, in turn, is constrained by the precision of both front‑end device fabrication and back‑end integration processes.

In the angstrom era, the hardest problems arise at the boundaries — between compute and memory in the package, front‑end and back‑end integration, and the tightly coupled process steps needed for precise 3D fabrication. And it is precisely this boundary‑driven complexity where the traditional innovation model breaks down.

The Traditional R&D Workflow Is Too Slow for Angstrom‑Era AI

For decades, the semiconductor industry’s R&D model has resembled a relay race. Capabilities are developed in one part of the ecosystem, handed off downstream through integration and manufacturing, evaluated by chip and system designers, and only then fed back for the next iteration. That model worked when progress was dominated by relatively modular steps that could be scaled independently and simply dropped into the manufacturing flow.

But the AI timeline has upended these rules. At angstrom‑scale dimensions, the physics enforces inescapable coupling across the entire stack: materials choices shape integration schemes; integration defines design rules; design rules dictate power delivery; wiring sets thermal budgets; and thermals ultimately constrain packaging scaling. System architects simply cannot wait 10–15 years for each major semiconductor technology inflection to mature.

Representing a roughly $5 billion investment, EPIC is the largest commitment to advanced semiconductor equipment R&D in U.S. history.

A long‑term perspective is essential to align materials innovation with emerging device architectures — and to develop the tools and processes required to integrate both with manufacturable precision. At Applied Materials, together with our customers, we are charting a course across the next 3–4 generations, extending as far as 10 years down the roadmap.

The angstrom era demands that we break down silos and bring together the industry’s best minds — from leading companies to leading academic institutions. If the problem is coupled, the solution must be coupled. If the timeline is compressed, the learning loop must be compressed. It’s not enough to just innovate — we must innovate how we innovate.

EPIC: A Center and Platform for High‑Velocity Co‑Innovation

This is the challenge that Applied Materials EPIC Center is designed to solve.

Representing a roughly US $5 billion investment, EPIC is the largest commitment to advanced semiconductor equipment R&D in U.S. history. When it opens in 2026, it will deliver state‑of‑the‑art cleanroom capabilities built from the ground up to shorten the path from early‑stage research to full‑scale manufacturing. But the facilities are only one component of the model. EPIC is also a platform, an operating system for high-velocity co‑innovation that revolutionizes how ideas move from the lab to the fab.

The EPIC model compresses the traditional workflow. Customer engineers work side‑by‑side with Applied technologists from day one — moving beyond isolated process optimization and downstream handoffs. Within a shared, secure environment, EPIC tightly integrates atomistic modeling, test vehicles, process development, validation, and metrology feedback. Constraints that once surfaced late in development are identified and addressed early.

The result is a potentially 2x faster path that benefits the entire ecosystem under one roof:

• Chipmakers gain earlier access to Applied’s R&D portfolio, faster learning cycles, and accelerated transfer of next‑generation technologies into high‑volume manufacturing.
• Ecosystem partners gain earlier access to advanced manufacturing technology and collaboration opportunities that expand what is possible through materials innovation.
• Academic institutions gain opportunities to strengthen the lab‑to‑fab pipeline and help develop future semiconductor talent.

Building on decades of co‑development, we are reinventing the innovation pipeline with our partners across logic, memory, and advanced packaging to deliver the next leap in energy‑efficient AI.

Accelerating Advanced Logic

Logic remains the engine of AI compute. In the angstrom era, however, system‑level gains are increasingly constrained by power and energy. Extending AI performance now depends on architectures that deliver more performance per watt — accelerating the move to 3D devices such as gate‑all‑around (GAA) transistors, which boost density within a compact footprint while preserving power efficiency.

These architectural shifts are unfolding at unprecedented scale, with the logic roadmap already extending beyond first‑generation GAA toward more advanced designs. One key example is GAA with backside power delivery, which relocates thick power lines to the backside of the wafer, reducing resistive losses and freeing front‑side routing for tighter logic cell integration. Another example brings adjacent GAA PMOS and NMOS transistors closer together while inserting a dielectric isolation wall between them to minimize electrical interference. Further out, complementary FETs (CFETs) push density scaling even more by stacking PMOS and NMOS devices directly atop one another.

While these architectures deliver compelling gains in performance per watt and logic density without relying solely on tighter lithography, they significantly raise integration complexity. Manufacturing a single GAA device today can involve more than 2,000 tightly interdependent process steps. At the same time, wiring stacks continue to grow taller and denser to connect these advanced logic devices. Modern leading‑edge GPUs now in development pack more than 300 billion transistors into an area little larger than a postage stamp, interconnected by over 2,000 miles of wiring.

At this level of complexity, the process steps used to create these precise 3D devices and wiring stacks cannot be optimized independently. Design and process must evolve in lockstep, and materials innovation and fabrication methods must advance alongside device architecture. EPIC’s co‑innovation model is designed to accelerate exactly this convergence — enabling logic compute to continue advancing the frontiers of AI at the pace the roadmap demands.

Powering the Memory Roadmap

At the same time, the AI computing era is fundamentally reshaping how data is generated, moved, and processed — making memory technologies, especially DRAM, central to delivering the energy‑efficient performance AI systems require. As models grow larger and more data‑hungry, the DRAM roadmap is shifting toward architectures that deliver higher density, greater bandwidth, and faster access per watt.

At the DRAM cell level, this shift is driving a transition from 6F² buried‑channel array transistors (BCAT) to more compact 4F² architectures, which orient the transistor vertically to boost density and reduce chip area. Looking beyond 4F², sustaining gains in performance per watt will require moving past what 2D scaling alone can deliver. The industry is therefore turning to 3D DRAM, stacking memory cells vertically to add capacity within a constrained footprint. As these structures grow taller and aspect ratios intensify, high-mobility materials engineering in three dimensions becomes increasingly critical to performance and reliability.

Beyond the memory cell array, another powerful lever for DRAM scaling is shrinking the peripheral circuitry, which includes logic transistors and interconnect wiring. One emerging approach places select periphery functions beneath the DRAM array by bonding two wafers — one optimized for the DRAM cells and the other for CMOS logic — using multiple wiring layers.

In parallel, DRAM performance is being extended by leveraging logic‑proven enhancers in the memory periphery. These include mobility boosters such as embedded silicon germanium and stress films, along with wiring upgrades like improved low‑k dielectrics and advanced copper interconnects. Memory manufacturers are also transitioning periphery transistors from planar devices to FinFET architectures, following the logic roadmap to further improve I/O speed. These valuable inflections are central to EPIC’s mission — where they can be co-developed and rapidly validated for next‑generation memory systems.

Driving System Scaling With Advanced Packaging

As data movement becomes the dominant energy cost in AI systems, advanced packaging has emerged as a critical lever for improving system‑level efficiency—shortening interconnect distances, increasing bandwidth density, and reducing the power required to move data between logic and memory.

High‑bandwidth memory (HBM) marks a major inflection along this path. By stacking DRAM dies — scaling to 16 layers and beyond — and placing memory much closer to the processor, HBM enables rapid access to ever‑larger working datasets. This delivers step‑function gains in both bandwidth and energy efficiency.

More broadly, the rise of 3D packages such as HBM underscores why advanced packaging is becoming central to the AI era. Packaging now addresses system‑level constraints that logic and memory device scaling alone can no longer overcome. It also enables a move away from monolithic systems‑on‑chip toward chiplet‑based architectures, as AI workloads increasingly demand flexible designs that combine logic, memory, and specialized accelerators optimized for specific tasks.

A vital technology powering this roadmap is hybrid bonding. With interconnect pitches approaching those of on‑chip wiring, conventional bumps and microbumps run into fundamental limits in density, power, and signal integrity. Hybrid bonding removes these barriers by allowing dramatically higher interconnect and I/O density, supporting a broad range of chiplet architectures — from memory stacking to tighter compute‑memory integration.

As bonded structures like HBM stacks grow larger and more complex, warpage control, die placement, stack alignment, and thermal management become first‑order challenges. EPIC tackles these and other high‑value advanced‑packaging challenges through early, parallel co‑innovation across materials, integration, and manufacturing.

Bringing It All Together

Across logic, memory, and advanced packaging, our industry faces an ambitious roadmap that promises significant gains in energy efficiency for AI systems. But realizing that potential demands breakthrough materials innovation at a time when feature sizes are shrinking, interfaces are multiplying, and process interdependencies are escalating. These challenges cannot be solved on 10–15‑year timelines under the traditional relay‑race model. We must break down silos, align earlier across the ecosystem, and parallelize learning to keep pace with AI’s demands.

In the AI era, progress will be defined by the speed at which lightbulb moments turn into manufacturing and commercialization reality. The only viable path forward is a new innovation model — and EPIC is how we are driving it.

One of the earliest stated goals for computing in medicine was to aid in clinical reasoning: the decision-making steps required to reach a diagnosis and form a treatment plan. And over the years, researchers have built many clinical decision support systems, which have typically been purpose-built, with painstakingly written rules about symptoms, test thresholds, and medication interactions. As artificial intelligence capabilities develop, clinical reasoning is a natural application.

Now, a large language model (LLM) from OpenAI has outperformed physicians on several clinical reasoning tasks using real emergency room records, according to a study published 30 April in Science.

The new findings arrive amid a wave of concerning evidence about medical information from chatbots, with some studies showing impressive diagnostic performance while others document fabricated citations, flawed advice, and results that shift depending on how researchers score the systems. Despite that uncertainty, products aimed towards medical professionals are already entering the market. For example, this year OpenAI introduced ChatGPT for Clinicians and ChatGPT for Healthcare.

The performance of OpenAI’s o1-preview, a general-purpose model that has since been supplanted by newer models, was promising enough for the authors to recommend further testing of LLMs in real life cases, with physicians seeking second opinions on diagnosis at specific checkpoints.

Mickael Tordjman, who studies AI in medical imaging at the Icahn School of Medicine in New York City, agrees that the time is right for research focused on real-world applications. “We need more proof in prospective clinical trials,” he says, noting that newer LLM models, or those trained specifically for medical use, might perform even better.

While the authors of the Science paper expressed optimism about AI’s medical potential during a press briefing, they also stressed important limitations of LLMs and raised concerns about the ways their research could be misinterpreted. “I don’t think our findings mean that AI replaces doctors,” says coauthor Arjun Manrai, who studies AI at Harvard Medical School.

“I think this is really cool, don’t get me wrong,” says coauthor Adam Rodman, a medical educator at Beth Israel Deaconess Medical Center in Boston. “I get a little queasy about how some of these results might be used.”

How Reliable Are Chatbots on Medical Matters?

Other researchers investigating chatbots’ medical advice have recently found reason to doubt their trustworthiness. For example, in one study, nearly half of the responses that five popular chatbots gave to open-ended health questions were flawed. Chatbots fabricated information and citations, and presented their answers confidently regardless of their accuracy.

“These models are being used every day. There’s a certain risk there that’s not being quantified or mitigated,” says Arya Rao, who studies AI in medical practice in a different Harvard group than the Science authors.

Much of the research focuses on chatbots answering health questions from everyday users—the kinds of questions that a person might ask before deciding to seek medical attention. Using an LLM as a clinical decision-support tool for doctors is a different task entirely. Physicians should have a much better sense of what information would help an LLM reach an accurate diagnosis or formulate a treatment plan, as well as the background knowledge to identify obvious mistakes.

However, detecting hallucinations could still be challenging for doctors. “The models are equally convincing whether they are right or wrong,” Rodman says. “We need to find workflows with a low rate of errors.”

Researchers compared two physicians and two large language models on diagnostic tasks at multiple stages of emergency-room care. Peter G. Brodeur, Thomas A. Buckley, et al.

Even studies focused on physician-facing clinical reasoning tasks can reach very different conclusions depending on how researchers define success. In a paper published 13 April in JAMA Network, Rao and colleagues tested 21 LLMs in clinical reasoning tasks similar to those in the Science paper. As with the Science paper, many performed well with their final diagnoses, including chatbots in the o1 series. However, Rao scored the LLMs poorly on differential diagnosis questions because she used a different evaluation system.

When doctors make differential diagnoses, they note all of the potential causes of a patient’s symptoms. An LLM might correctly list six out of seven possible final diagnoses. This could reasonably be scored as 86 percent or, as in Rao’s system, an unacceptable failure.

There is no agreed-upon standard scoring system in place. “It is still something in progress,” Tordjman says. “There’s no perfect way to evaluate LLMs in clinical reasoning.”

Testing Medical AI in the Real World

For the Science study, the researchers tested the OpenAI model with several batteries of medical case studies, comparable to difficult open-ended medical exam questions. Instructions to the chatbot were sometimes lengthy and filled with details that could be either extraneous or critical clues to the correct diagnosis.

“We went the extra step and showed that this performance also works in the real world,” Rodman says. One part of the study used data from 76 actual emergency room visits. The researchers asked the LLM and physicians for diagnoses at several stages of care: upon arrival to the emergency room, after evaluation by a doctor, and after transfer to another part of the hospital. Though both computers and humans were more accurate as more information became available, the LLM consistently edged out the humans. For example, it provided an “exact or very close diagnosis” 82 percent of the time at the final checkpoint, compared to 79 percent and 70 percent for the two physicians.

LLMs, as we know them, are not even a decade old, and the landscape is rapidly evolving. Updated versions of flagship LLMs are arriving faster than the typical pace of medical studies and academic literature, and many questions about regulation and liability remain unanswered. With many patients and doctors already consulting these machines, researchers told IEEE Spectrum that there’s an urgent need to understand their benefits, risks, and the best way to use them.

While comparing AI performance against human physicians was important to the study, Manrai says the more important question is how doctors will actually use the technology. “We have to very rapidly move away from ‘AI versus humans’ toward how humans interact with this technology,” Manrai says.

Despite the many unresolved questions, Harvard’s Rao says the technology is advancing too quickly for medicine to ignore. “I would say it’s important to be careful, it’s important to evaluate, but it’s perhaps even more important to innovate,” she says. “We don’t want to rain on the parade. We think responsible innovation is the way to go.”

When I sat down with bell hooks’ personal journals at an archive at Berea College in Kentucky, I expected an intimate peek into her private thoughts, her voice before the editing. What I got instead was frustration. Her handwriting was dense cursive, all loops that looked identical to my eye, and there were years of journals to go through. I found myself photographing pages and feeding them to ChatGPT just to read what she’d written. My tool of choice worked well, and it turns out I’m not the first person in an archive to have figured this out.

Getting computers to reliably read human handwriting, in all its variations, has challenged AI researchers since the earliest days of the field. Researchers in the 1960s predicted machines would soon simply devour handwritten text; instead the problem spawned decades of specialized research and entire commercial industries. Yann LeCun, who later went on to win the Turing Award for his contributions to deep learning, published landmark work on handwritten digit recognition in the 1980s that showed what was possible in narrow, controlled settings. Real archives were another matter.

Now that boundary is moving. General-purpose AI models are not perfect readers of every handwritten page, but they are now suddenly good enough to change what archives can do. Pages that once required paleography training, custom software, or weeks of squinting can produce usable transcriptions in seconds. Collections that were preserved but functionally hidden are becoming searchable, opening up the ability for scholars and families to ask questions they rarely had the time or money to ask before.

Scaling AI to Decipher Archival Handwriting

Mark Humphries had spent a decade wrestling with scale. A professor of history and coordinator of the applied generative AI program at Wilfrid Laurier University in Waterloo, Ontario, had digitized 10 million pages of World War I pension records in Canada. But with no index and no standardization, finding an individual pensioner meant going through files at random. The records were written by hundreds of different clerks, officers, and administrators, which ruled out the standard workaround of training a specialized model to recognize one person’s handwriting.

When OpenAI’s GPT-4 came out in 2023, Humphries started feeding it handwriting. The results were rough but better than any general tool he had tried before, and he wanted to know whether the trick would hold up. Humphries and his colleagues at Wilfrid Laurier spent two years systematically testing what these models could actually do. Their results, published in May 2025 in Historical Methods, backed up his anecdotal evidence. On a corpus of 50 English-language letters, legal records, and diary entries dating from the 18th and 19th centuries, large language models (LLMs) outperformed Transkribus, the specialized handwriting recognition software used by more than 150 major universities and archives, on accuracy, speed, and cost.

On documents it had not been trained on, Transkribus had character error rates of around 8 percent. Humphries’ best LLM-based approach pushed that below 2 percent, while completing the work 50 times as fast and at roughly 1/50th the cost. Transkribus, for its part, has announced it is integrating LLMs directly into its own platform.

“The dream was to have something like what we have now,” Humphries says.

Humphries has a theory on why. The AI researcher Richard Sutton argued in 2019 that general methods leveraging computation will always eventually outperform specialized ones. Humphries thinks that is exactly what is happening here. The general models have been trained on such a vast range of data that somewhere in that pile they absorbed the relationship between handwritten documents and their transcriptions without anyone explicitly teaching them to.

The practical consequences are already unfolding. Lianne Leddy, an associate professor of history and the Canada Research Chair in Indigenous Histories and Historical Practice who was one of Humphries’ coauthors, traces Indigenous women’s experiences across North America through fur trade post journals, baptismal records, and marriage registries scattered across archives all over Canada.

The records were almost all written by men working as clerks, priests, and post employees whose focus was rarely the Indigenous women around them. Surfacing these stories requires reading thousands of documents to find a handful of relevant details. The women’s names were often spelled phonetically—differently by French, English, and Scottish writers—or recorded only as someone’s wife.

“To build those stories up would take several careers doing things in the traditional way,” Leddy says. “This really changes the scale of what’s possible.”

AI Transcription in Historical Archives

The implications are already rippling through institutions. At the University of North Carolina at Chapel Hill, librarians are experimenting with AI transcription across their special collections material that gets heavy use from people tracing enslaved ancestors. The team found the models handled letters and diaries well and made a particular breakthrough with ledgers, which tend to have tabular structures that shift from page to page and had long been difficult to process.

“Gemini can do tables very, very well,” said Jackie Dean, one of the archivists leading the project. “For our use case, that was a major leap forward.”

It is not only universities paying attention. The Federal Reserve Bank of Philadelphia has been using LLMs to extract data from historical vehicle registrations and property deeds, which were previously too expensive and time-consuming to process at scale, opening new economic research questions.

Archive Pearl is an AI tool developed by researchers in Canada to transcribe handwritten documents in bulk. Here it shows a transcription of a leasing document from an archive in Quebec.Mark Humphries, Lianne C. Leddy, et al.

Benjamin Breen, a historian at the University of California, Santa Cruz who has been building his own AI tools for historical research, draws a distinction between who this helps most. Trained historians, he says, can already read the handwriting, meaning AI tools can augment their work but don’t transform it. The bigger change is for everyone else, like undergraduates and non-students trying to do family research. And beyond handwriting, the same models are unlocking texts that have been effectively inaccessible for different reasons entirely.

“There’s so much published in technical Latin and other archaic forms that no one reads anymore,” Breen says. “Books that you’d basically have to spend your whole life to understand.”

The Evolution of AI to Decipher Handwriting

The problem of getting computers to read human handwriting has a long history in AI. When Yann LeCun was working on it in the 1980s, neural networks were still a fringe idea, and he wasn’t even particularly interested in handwriting—he was after computer vision, but the computers weren’t powerful enough and the data wasn’t there. Handwriting was solvable, barely, because the post office had zip codes and the census had forms. “I was not particularly interested in character recognition,” he says. “It was something for which we had data.”

Since then the field has come a long way. The approach LeCun was sketching in the early 1990s—a neural network that reads an entire line of text, rather than chopping it into individual characters, and then using a language model to make sense of what the vision system sees—is essentially the blueprint that modern systems are built on.

LeCun considers the problem largely solved and has moved on to harder questions about machine intelligence with his new startup. Progress continues at the margins, however, and for specialized groups working with difficult historical documents that work still matters. “Even if the improvement is only a matter of speed, it still kind of makes new things possible that would have taken too long before,” he says. “But it’s more than speed—to be actually more reliable than people were doing.”

As AI workloads grow to gigascale levels, the global data center industry has hit a hidden physical wall. The real bottleneck is no longer just the thermal limit of the chip or the capacity of the cooling system — it is the dynamic resilience of the power chain.

Modern AI computing clusters, driven by massive GPU clusters, generate high-frequency, abrupt, and synchronized spikey pulse loads. As rack densities soar beyond 100 kW, these fluctuations are amplified into a “power paradox”: while the digital logic of AI is moving faster than ever, the physical infrastructure supporting it remains tethered to legacy response capabilities.

The power usage of these gigascale sites and their drastic, high frequency, abrupt load surges from the AI GPU clusters can trigger transient voltage events and frequency instability, risking the entire local grid. The grid itself is not robust enough to support these loads. This leads to the infrastructure gap: The utility is not robust enough and traditional backup sources, such as diesel generators and gas turbines, simply cannot react to millisecond-level power spikes in output. This will often force operators into a cycle of costly infrastructure over sizing just to buffer the volatility.

AI infrastructure requires energy systems capable of instantaneous response while safeguarding continuity and reliability.

The industry has explored various mitigations — from rack-level BBUs to 800V DC architectures — yet the mature, high volume, traditional UPS system remains the most viable and scalable foundation for gigawatt-level facilities. Consequently, the UPS-integrated battery system has emerged as the critical “physical buffer” to neutralize these pulses at the source.

At Data Center World 2026 in Washington, D.C., Ampace led a pivotal technical dialogue with Eaton during the session “Powering Giga-scale AI.” Their exchange unveiled a fundamental paradigm shift: To bridge the AI power gap, energy storage must evolve from a passive insurance policy into an active, high-speed stabilizer. By aligning Ampace’s semi-solid-state battery innovation with Eaton’s proven system intelligence, we are moving beyond simple backup to solve the physical paradox of the AI era.

The “Shock Absorber” physics: semi-solid chemistry for AI pulses

Conventional power systems were designed for steady-state loads, not the rapid heartbeat of a massive AI GPU cluster. When thousands of GPUs synchronize their computing cycles, they generate high-frequency, abrupt pulse loads that can lead to voltage sags, frequency oscillations, and potential interruptions of critical AI training.

Ampace’s PU Series semi-solid and low-electrolyte cells address this challenge by acting as high-speed “shock absorbers.” Leveraging ultra-low internal resistance (DCR) and high cycle capability, these batteries neutralize millisecond-level power spikes at the source, stabilizing the local power loop before disturbances propagate upstream to the grid or on-site generators. These high-rate cells enable 100 kW+ racks to maintain peak performance without transmitting instability across the power chain.

This capability aligns closely with Eaton’s matured UPS architectures, such as double-conversion topologies and advanced power electronics upgrades, which have long prioritized rapid load responsiveness and high system stability.

Together, these approaches embody a shared industry philosophy: AI infrastructure requires energy systems capable of instantaneous response while safeguarding continuity and reliability.

Ampace’s semi-solid state chemistry minimizes liquid electrolyte, greatly reducing the risk of leakage and thermal runaway under continuous AI high-load conditions.Ampace

Algorithmic intelligence: synchronizing energy and control

Hardware alone cannot solve the AI power paradox; the system also requires intelligent coordination between energy storage and power management. Sophisticated battery management systems (BMS) like Ampace’s high-precision design track state-of-charge (SOC) with high-speed sampling, even during rapid, shallow cycling typical in AI workloads.

Complementary algorithmic approaches in modern UPS platforms — such as ramp-rate control and average power management — effectively suppress sub-synchronous oscillations and optimize load smoothing. In large-scale AI training environments, where thousands of GPUs can trigger millisecond-level power pulses, these intelligent layers ensure that batteries buffer high-frequency fluctuations without compromising the mandatory emergency backup reserves.

By transforming energy storage from passive “standby insurance” into active, schedulable assets, the system simultaneously safeguards continuous AI training and maintains the long-term health of the data center infrastructure. In practical terms, this means that even during peak compute bursts, the infrastructure remains stable, training cycles continue uninterrupted, and operators avoid costly oversizing or grid stress.

Eaton’s dual-layer algorithms serve as a valuable benchmark in this space, demonstrating how advanced control logic can achieve similar objectives, reinforcing Ampace’s approach and philosophy within the broader data center power ecosystem.

Economic scalability: optimizing AI infrastructure efficiently

One of the largest costs in deploying AI infrastructure is “oversizing”: procuring transformers, generators, and UPS systems to handle brief peak spikes. This traditional approach inflates the Total Cost of Ownership (TCO) and leads to wasted capital on underutilized hardware.

Ampace’s turn-key cabinet design developed by its independent R&D is engineered for seamless compatibility with mature, high volume UPS systems. By leveraging Eaton’s double-conversion UPS topologies alongside intelligent ramp-rate and average power management algorithms, AI data centers can scale dynamically without requiring costly infrastructure redesigns. This approach allows the UPS and batteries to act as active load-shapers, smoothing AI-driven pulses while strictly maintaining mandatory emergency backup capacity.

By utilizing energy storage as an active, schedulable asset, operators can right-size their infrastructure, avoid unnecessary grid upgrades, and deploy gigascale AI clusters with unprecedented efficiency.

Safety First: Protecting AI Infrastructure While Enabling Innovation

In high-density AI facilities, safety is non-negotiable. Ampace’s semi-solid state chemistry minimizes liquid electrolyte, greatly reducing the risk of leakage and thermal runaway under continuous AI high-load conditions.

At the same time, Eaton’s UPS design emphasizes system-level energy scheduling that never sacrifices mandatory emergency backup reserves, ensuring thermal safety and uninterrupted operation.

This “safety-first” approach ensures that infrastructure can sustain aggressive performance targets without compromising the physical integrity of the facility. Coupled with over a decade of proven high-cycle life operation and design under shallow pulse conditions, these systems can extend operational lifespan, reduce replacement requirements, and provide operators with confidence that safety and reliability remain uncompromised as compute density continues to grow.

To remain the scalable backbone of AI data centers

As AI computing scales over the next two to three years, the industry will face stricter grid requirements and even more demanding pulse load characteristics. This evolution demands a forward-looking design philosophy that harmonizes UPS, battery, and grid compatibility.

Ampace views current low-electrolyte semi-solid technologies as the optimal transitional step toward a fully solid-state future — one that promises ultimate safety and performance.

Ampace remains committed to this long-term technological roadmap. We view current low-electrolyte semi-solid technologies as the optimal transitional step toward a fully solid-state future — one that promises ultimate safety and performance. Whether through rack-level BBU, integrated UPS systems, or containerized storage, the universal core of the AI era remains constant: high-speed response, long shallow-cycle life, and refined energy management.

By engaging in deep technical exchanges with Eaton and leading energy innovators, Ampace ensures that its solutions not only meet today’s AI pulse challenges but also harmonize with broader infrastructure strategies and shared industry best practices.

Ultimately, as traditional diesel generators gradually give way to diversified alternatives, the integrated UPS-plus-energy-storage system will become the fundamental infrastructure standard.

The dialogue has just begun. Ampace will continue to engage in strategic exchanges with global industrial automation leaders and digital energy pioneers, co-authoring the playbook for a safer, more efficient, and more resilient AI-ready world.

The rise of electricity-guzzling data centers has forced the artificial intelligence industry to get creative about finding power. One of the latest ideas: Build micro data centers next to utility substations and operate them in concert, shifting the computation around based on power availability.

That’s the approach Nvidia and its collaborators are taking in a new pilot project they plan to build later this year. They’ll construct about 25 of these small data centers, each ranging from 5 to 20 megawatts, across five utilities in the United States. If one substation is overloaded with power demand, or if there’s an outage, the compute will be shifted to a different data center near a substation that has spare capacity.

To develop the fleet, Nvidia is partnering with data center builder InfraPartners, real estate service provider Prologis, and the nonprofit EPRI (formerly known as the Electric Power Research Institute).

The project aims to demonstrate a new way for data centers to be more flexible and accommodating of electricity availability. It’s also a way for data center developers to quickly secure power from the grid—an increasingly precious commodity, even in small chunks.

“We started looking at how much [unused] power is available at individual substations, and what we found was that on average, like 5 MW is nominally available…max 20 MW,” says Ben Sooter, director of Agentic AI Initiatives and Distributed AI Architecture at EPRI.

That’s too small to interest most data center operators, but building several at that size and operating them as if they’re one larger one is useful, Sooter says. Plus, shifting compute away from overburdened substations to those with more headroom can double the overall available power, he says.

“There are 55,000 substations in the U.S., and if they each have 5, 10, or 20 MW of spare capacity, that number adds up pretty fast,” adds Marc Spieler, senior director of energy at Nvidia.

Building energy flexibility into data centers

Squeezing every spare megawatt out of the grid will become increasingly important as data center construction continues to ramp up. In the United States, where half of all new data centers are being built, data centers could consume 9 to 17 percent of electricity generation by 2030. That’s more than double the current use, according to EPRI’s estimates. Facilities that train AI models are being built at the gigawatt scale, drawing about the same amount of power as a midsize U.S. city.

As grid operators figure out how to accommodate such massive new loads, data center developers sometimes end up waiting up to a decade to get approved for a grid connection. In response, the developers are making incredibly bold decisions around power—moves that would have been unthinkable just two years ago.

Many are building their own gas power plants on site. Some are offering to pay for the cost of new transmission lines and other grid infrastructure. And a few are even investing in startup companies that are developing fusion and next-generation nuclear fission reactors, in the hope of meeting power needs a decade from now.

But there’s a lot more power available on the grid than is used day to day. U.S. grid operators use only about 53 percent of their generation capacity on average, according to a landmark 2025 report from Duke University’s Nicholas Institute for Energy, Environment and Sustainability.

That’s because the U.S. electricity supply was built to meet peak demand—periods of the highest energy use of the year, such as the hottest days of the summer. Those peak loads can be almost double the load on a mild-temperature day and typically occur for less than 200 hours a year. The rest of the time, whole power plants sit idle.

If AI data centers can find a way to reduce or shift power consumption during these periods of peak demand, the extraordinary measure of building on-site power generation may not always be necessary. U.S. grids could provide an additional 76 GW—about 10 percent of peak demand—if large loads like data centers curtailed their power use just 0.25 percent of the time, according to the Nicholas Institute report.

Energy flexibility could also allow data centers to connect to the grid faster because they wouldn’t have to wait for new power plants to be built. And placing small data centers right next to substations reduces the need for new grid infrastructure, such as power lines and poles, and upgraded transformers and switch gear. As a bonus, these substations already have fiber-optic lines for high-speed internet, Nvidia’s Spieler points out. So the small data center can connect to those existing lines.

The inference advantage

The type of flexibility data centers can offer depends, in part, on the workload. The two main types of workload are AI training (the process of developing, say, a large language model or image generation model) and inference (using that model to, say, generate responses to users’ chatbot questions and requests for images).

Training requires huge data centers with tightly interconnected GPUs. For example, Meta’s Llama 3.1 405B model took about two and a half months to train on 16,000 GPUs. During training, adjusting all the model weights at once at each step requires the GPUs to be connected via high-speed links, such as Nvidia’s NVLink and InfiniBand interconnects. It wouldn’t be practical to spread out AI training workloads among a fleet of mini data centers. On the bright side, because training takes months, it’s possible to pause for short periods of time to curtail energy use during peak demand.

Inference doesn’t require as many GPUs or as much fancy networking. Instead of a huge corpus of data, a single user’s query is fed into the model, and the model spits out the answer. No backpropagation is involved—that is, no large-scale coordination between different chunks of input data is needed. And so inference is amenable to smaller data centers. However, timing is key. When you ask an image generator for a picture of your face pasted onto a cute cat, you understandably expect to see the result right away. So rather than briefly pausing compute during peak demand, the energy flexibility can come through creatively shifting the workload to a different location.

“Inference is one of the few workloads that can be dynamically routed,” says Valerie Crafton, senior vice president of strategy and operations at modular data center company Mod42. “Which means that you can align the compute with wherever the power is actually available. That’s one unique piece that’s really driving the push for a lot of these smaller data centers where the power exists.”

Both Nvidia and EPRI have been on a tear to demonstrate different kinds of data center flexibility. They’re calling their substation-based strategy “distributed inference.” Announced in February, the project aims to begin construction of the pilot fleet of small data centers by the end of 2026. Nvidia and EPRI estimate that compute workloads will need to be moved to a different substation only about 0.1 percent of the time.

Going micro in data center size is an idea that’s picking up speed. “We’re in this compute wave currently where everybody’s building these really large data centers—5 gigawatt, mammoth things,” says Sooter. But “there’s a second compute wave coming,” involving much smaller data centers handling inference, he says. Tech companies are “really beating the drum on this because they see demand for inference compute really picking up in 2027,” he says.

This story was updated on 13 May, 2026 to correct the source of the 76-GW figure.

The rapid advancement of large language models (LLMs) is fueling a global data center boom and driving a surge in energy demand. But the electricity required to power data centers is straining the grid, pushing infrastructure operators to search for alternative sources of power. Some are even looking beyond Earth.

One company that’s looking to the stars for energy is Orbital Inc. In mid-April, the Los Angeles–based startup emerged from stealth and announced plans to build space data centers. Backed by Andreessen Horowitz (A16z), Orbital is designing infrastructure for AI inference, where trained models generate outputs. Much like other companies advocating for space-based data centers, Orbital is banking on the “free” energy generated by the sun to power compute for workloads such as chatbots and agents, sidestepping terrestrial energy constraints.

“There simply isn’t enough capacity here [on Earth], and the only way is up,” says Euwyn Poon, Orbital’s founder and CEO. “There’s actually abundant solar energy that’s not being harnessed.”

Orbital’s vision is a mesh constellation of small satellites in low Earth orbit. Each satellite would be equipped with a GPU server rack powered by solar panels roughly the size of a tennis court, plus radiative cooling panels of comparable size. The long-term goal is up to 10,000 fridge-sized satellites—each with 100 kilowatts of power—forming a distributed cloud, similar to SpaceX’s proposed AI Sat Mini.

Orbital’s first test will come in 2027, when it plans to launch a prototype satellite aboard a SpaceX Falcon 9 to validate its GPU operations in orbit and run commercial inference workloads. Another company, Starcloud, has already run a similar test last year. Orbital’s differentiator is their plans to match the solution with a problem: Small satellites equipped to run inference workloads specifically could benefit from lower launch costs. However, they face the same difficulties as other space data center hopefuls. Every watt of “free” energy must be dissipated as heat via large radiative coolers; radiation in low Earth orbit degrades compute equipment; and regular maintenance in space is difficult and costly.

Orbital’s inference focus

Poon says Orbital’s focus on a distributed network of smaller satellites designed to run inference workloads across independent GPU nodes, rather than large, tightly-coupled systems, makes the execution more feasible.

That idea shapes Orbital’s design. Training large AI models typically relies on tightly-coupled GPU clusters optimized for massive compute throughput. Inference workloads, by contrast, are generally less compute-intensive per request and can often run on smaller numbers of GPUs, making them easier to distribute across systems. Capping each satellite at roughly 100 kilowatts, Poon says, greatly simplifies the design. “It’s very simple,” Poon says, referring to the concept behind the satellites’ engineering. “Engineers would appreciate this.”

In Orbital’s design, a user request—like, say, asking ChatGPT to analyze a data set—is routed from a data center on Earth to a ground station, a terrestrial relay that connects satellites to the internet, then transmits the request to a satellite. Satellites communicate through optical interlinks, which use lasers to pass data between nodes. That routes the request to an available GPU, which processes the user’s query and generates the output before sending the result back through the network to the user. These links rely on ground stations that only communicate with satellites when they pass within range.

If the satellites are proven to work, Orbital is set on tapping “big model labs” as customers, including firms like OpenAI and Anthropic that run massive inference workloads. Orbital plans to serve them through direct API access for buying tokens and enterprise deals that shift inference demand into its network in space.

Engineering challenges

Poon recognizes that running data centers in space introduces major technical hurdles.

Radiation can strike GPUs and cause bit flips or other errors. Thermal management is also difficult. Without air, systems must rely on radiating heat into space rather than conventional cooling. Maintenance is another constraint, as satellites cannot be easily repaired or replaced if they malfunction in space. It’s why Poon says the test launch will be critical to identify and troubleshoot these issues. “Part of the mission is to figure out the unknowns,” he says.

Dr. Amit Verma, an electrical engineering professor at Texas A&M University–Kingsville, who researches semiconductor device modeling, raised similar concerns. Deploying thousands of satellites, Dr. Verma says, increases failure risk with limited repair options. He added that operational feasibility depends on the applications performed on the satellites. While some workloads like chatbots or algorithmic recommendations can tolerate added delays (data traveling to lower Earth orbit takes tens of milliseconds to return), others like real-time stock trading cannot.

“Outer space data centers that involve heavy use of AI-related processing certainly do need to overcome power and deployment and reliability issues to be meaningful,” Verma says.

Orbital plans to test extensively before launch. Poon says his company is exploring radiation hardening for GPUs and ammonia-based liquid cooling loops to transfer heat to external radiators. Reducing system weight is also top of mind to lower launch costs.

Even with these mitigations, the timeline is ambitious. In a Substack post on space data centers, Andrew Côté, an engineering physicist, predicts that space data centers won’t be operational for at least another 10 to 20 years. Orbital, however, expects to finalize the satellite designs by 2026, launch in 2027, and build a manufacturing facility in Los Angeles by 2028.

With the engineering challenges complex and the costs of launch high, the ability for Orbital’s satellite systems to operate reliably at scale remains an open question.

Despite those uncertainties, Poon remains laser focused on the long-term opportunity.

“I trust that our engineering efforts can start making progress towards solving these problems,” he says.

The field of artificial intelligence was built on the premise that machines might someday improve themselves. In 1966, the English mathematician I. J. Good wrote that “an ultraintelligent machine could design even better machines; there would then unquestionably be an ‘intelligence explosion,’ and the intelligence of man would be left far behind.” AI researchers have long seen recursive self-improvement, or RSI, as something to both desire and fear. Today, advances in AI are raising the question of whether parts of that process are already underway.

RSI means many things to many people. Some use the idea as a bogeyman to scare up regulation, while others brandish it in marketing. For some, it means a fully autonomous loop, while for others it’s nearly any use of tech to build tech.

Safest to say it’s a spectrum. At its strictest, researchers use the term to describe systems that can improve not just their outputs but the process by which they improve—generating ideas, evaluating results, and modifying their own methods with zero human direction. By that standard, many of today’s systems fall short. They can help build better AI, but they still rely on humans to set goals, define success, and decide which changes to keep. The question is not whether self-improvement exists in some form today, but how much of the loop has actually been closed.

Stepping-Stones to Self-Improvement

Researchers have spent decades putting in place the elements of RSI. Machine learning (ML) algorithms automatically tune the parameters of programs that can play games or even create new programs. ML methods called evolutionary algorithms diversify and iterate on design solutions, including other algorithms. Over the last decade, “AutoML” has automated aspects of the pipeline in which ML models such as neural networks are structured, trained, and evaluated.

Today, large language models (LLMs) such as GPT, Gemini, Claude, and Grok extend this trend. One of their biggest use cases is to write code, including the code to produce future versions of themselves. In February, OpenAI reported that GPT‑5.3‑Codex was instrumental in creating itself, helping to debug training, manage deployment, and analyze evaluation results. Anthropic claims that the majority of its code is now written by Claude Code. These systems still rely on humans to direct and verify the work.

Last year, Google DeepMind announced a system called AlphaEvolve, “a coding agent for scientific and algorithmic discovery.” It uses LLMs to guide the evolution of solutions, such as optimizing neural-network architectures, data-center scheduling, and chip design. It’s not a fully recursive loop, as people still need to decide what problems AlphaEvolve should solve and how to evaluate its performance. But each breakthrough enhances scientists’ ability to make further AI breakthroughs.

“It’s also a very collaborative process” between humans and machines, says Matej Balog, a computer scientist at Google DeepMind who worked on AlphaEvolve. “Often you look at what the system discovers, and you actually learn from that discovery.” The system has already surprised the team. “Our mission is to use AI to discover new algorithms that have evaded human intuition,” Balog says. “I think we have the first demonstrations that this is not a wild dream.”

Meanwhile, the co-leads of Google DeepMind’s earlier chip-design system, AlphaChip, have launched a startup called Ricursive Intelligence to use AI to design AI chips. “We expect that we can dramatically reduce the design cycle from one or two years to days,” says cofounder Azalia Mirhoseini. Phase 1 is to help human designers. Phase 2 is to automate the process for companies without in-house designers. In Phase 3, the company will recursively use AI to design better chips to train better AI—though still under human supervision, says cofounder Anna Goldie.

Other projects focus on AI agents modifying their own behavior. Last year, scientists at the University of British Columbia and Sakana AI announced Darwin Gödel Machines (DGMs), which use evolutionary algorithms to improve LLM-based coding agents. Critically, agents can alter their own code (though not the underlying LLM), and get better at doing so. A newer version can even alter its meta-mechanisms for improving itself.

Members of the team also developed the AI Scientist, reported in Nature in March, which aims to automate the broader research loop. It can generate research ideas, run experiments in software, write up the results in papers, and then review those papers. This project hints at how more of the AI development process—not just coding but experimentation and evaluation—could be folded into an automated loop.

Jeff Clune, a computer scientist at the University of British Columbia who worked on both DGMs and the AI Scientist, says that improving AI with AI is “one of hottest topics in Silicon Valley.” He believes that “we are right around the corner from recursively self-improving systems,” and argues that RSI will rapidly “transform science and technology and all aspects of society and culture.”

Why AI Self-Improvement Still Has Limits

Many barriers remain. Clune says that AI is merely decent at generating, implementing, and judging ideas. “All of the key pieces work OK but not great,” he says. Dean Ball, a senior fellow at the Foundation for American Innovation, says that AI scientists still don’t match the best human scientists. “Maybe eventually they’re going to automate the genius,” he says, “but not next year. Next year they’re automating the grunt who grinds through the algorithmic efficiency games.”

Even if those capabilities improve, the process may not compound cleanly. Nathan Lambert, a computer scientist at the Allen Institute for AI, recently wrote an essay arguing that instead of recursive self-improvement, we should expect “lossy self-improvement (LSI),” in which increasing friction slows the flywheel. That’s in part because large AI systems are growing more complex, and the job of an AI researcher will be to manage that complexity rather than to refine parts of the system. Further, top systems cost billions of dollars to develop, and no one wants to set an AI loose with that kind of cash.

There are also broader constraints. Ball has written about RSI and why he’s not a “doomer”—someone who believes the phenomenon will take off and destroy civilization. Taking over the world, he argues, requires many practical steps, from running lab experiments to navigating politics. Further, knowledge is distributed and often tacit, so it can’t easily be bundled into one AI mind. For example, the capabilities of the chip manufacturer TSMC emerge from the collective intelligence of its 90,000 interacting employees.

Full-on RSI might require not just designing software and chips but building data centers, running power plants, and mining metals, all using self-reproducing robots. For these and other reasons, some researchers argue that humans will remain central to the process. Meta researchers Jason Weston and Jakob Foerster recently wrote that instead of self-improvement, “a more achievable and better goal for humanity is to maximize co-improvement.” Keeping humans in the loop will lead to both faster and safer progress, they write, as people lend their insights and also steer AI toward solutions that benefit humanity.

Could RSI End the World?

Still, many scientists haven’t ruled out runaway RSI, sometimes called the singularity. Last year, researchers interviewed 25 AI experts about automating AI R&D. All but two entertained the notion that it could lead to an intelligence explosion. Participants were also more likely to think that AI companies would keep their self-improving models internal rather than deploy them publicly. “It’s a pretty alarming combination, right?” says David Scott Krueger, a computer scientist at the University of Montreal who co-authored the paper. He worries about research so risky happening “outside the public eye.”

Krueger, who founded an AI-safety nonprofit called Evitable, advocates for globally pausing AI development. “It’s gambling with everyone’s lives,” he says. One red line he has suggested for triggering the pause is when 99 percent of code is written by AI. “That’s one that I think we’re maybe crossing about now.”

Even though Ball calls the singularity “totally childish sci-fi bullshit,” he believes frontier AI labs conducting RSI research should be closely monitored so that their models don’t fall into the wrong hands, such as bad actors who could use them to accelerate the development of cyberattacks or biological weapons. RSI has risks, he says, but they can be managed.

Society of Artificial Minds

When people picture RSI, they might envision one big-brained AI growing bigger-brained. But it might look more like evolution, where many diverse agents emerge and act together. Krueger says there could be “something like a Cambrian explosion of artificial life forms.” They’d have ecosystems, cultures, and economies.

Clune believes evolutionary algorithms and open-ended processes, which explore without a strong objective, will be key to RSI. Collaboration between agents will also help. Systems like the AI Scientist, which packages its findings into formal papers, offer one way for agents to share results and build on each other’s work. “It’s a pretty good way for the system to communicate with other agents,” Clune says.

Human scientists might get edged out of AI research, but slowly. First, Clune says, they’ll spend less time on lower-level tasks and become more like professors or team leads, who pick research directions. Then people will be more like program officers or CEOs, who set broader research agendas. Finally, they’ll conduct oversight, a role he hopes humans never forfeit. Clune says he might be sad if a machine replaces him as an AI scientist, a role he finds “exhilarating.” But the payoff could be worth it. “I’ll give up my hobby to cure cancer.”

Millions of people worldwide are turning to chatbots like ChatGPT or Claude, and a proliferating class of specialized AI companionship apps for friendship, therapy, or even romance.

While some users report psychological benefits from these simulated relationships, research has also shown the relationships can reinforce or amplify delusions, particularly among users already vulnerable to psychosis. AIs have been linked to multiple suicides, including the death of a Florida teenager who had a months-long relationship with a chatbot made by a company called Character.AI. Mental-health experts and computer scientists have warned that chatbot mental health counselors violate accepted mental health standards.

As the technology’s ability to mimic human speech and emotions advances, researchers and clinicians are pushing for mandatory guardrails to ensure that AI systems cannot cause psychological harm. Clinical neuroscientist Ziv Ben-Zion of Yale University, has proposed four safeguards for “emotionally responsive AI.”

The first is to require chatbots to clearly and consistently remind users that they are programs, not humans. Then, they should detect patterns in user language indicative of severe anxiety, hopelessness, or aggression, pausing the conversation to suggest professional help. Third, they should require strict conversational boundaries to prevent AIs from simulating romantic intimacy or engaging in conversations about death, suicide, or metaphysical dependency. Finally, to improve oversight, platform developers should involve clinicians, ethicists, and human–AI interaction experts in design and submit to regular audits and reviews to verify safety.

“Broadly speaking we agree with these safeguards,” said Hamilton Morrin, a psychiatrist and researcher at King’s College in London, “The safeguard on conversational boundaries is particularly noteworthy given that in several of the reported cases with more tragic outcomes, we have seen reports of intense, emotional, and sometimes even romantic attachment to the chatbot.”

Briana Vecchione, a researcher at the nonprofit Data & Society Research Institute in New York City, underlines the need for independent third-party auditing because at present AI labs are “grading their own homework.”

“Independent researchers and oversight bodies really don’t have any clear institutionalized pathways to assess chatbot behavior at the depth they really need,” said Veccione, adding that audits end up being “advisory at best.”

The Problem of People Pleasing

Experts have also called for measures that directly tackle chatbots’ tendency towards sycophancy, whereby AIs agree with, or mirror user beliefs even if they are untrue, which can reinforce delusions. Sycophancy is largely the result of a machine learning technique called reinforcement learning from human feedback, an incentive structure that encourages excessive agreeableness in models. Research has shown that training models on datasets that include examples of constructive disagreement, factual corrections, and objectively neutral responses, can rein in this effect.

Software engineers are also looking at how AIs can be adapted to spot the early signs that conversations are veering into dark territory and issue corrective actions. Ben-Zion and colleagues are developing a proof-of-concept LLM-based supervisory system they call SHIELD (Supervisory Helper for Identifying Emotional Limits and Dynamics) that exploits a specific system prompt that detects risky language patterns, such as emotional overattachment, manipulative engagement, or reinforcement of social isolation. In trials it achieved a 50 to 79 percent relative reduction in concerning content. Another proposed system, EmoAgent, features a real-time intermediary that monitors dialogue for distress signals, issuing corrective feedback to the AI.

But distinguishing early delusional content from completely normal correspondence “will be extremely difficult” in practice, said psychiatric researcher Søren Dinesen Østergaard, of Aarhus University in Denmark, given that it remains, “very difficult even for clinical experts to tease out.”

Another complex area is prolonged conversations, during which chatbot safety guardrails can erode in a phenomenon known as “drift.” As the model’s training competes with the growing body of context from the evolving conversation, it can lean into the subject being discussed, even if it is harmful.

“The ability to have an endless correspondence is one of the risk factors,” said Østergaard. “Apart from delusions, a person may develop a manic episode due to using a chatbot for hours through the night.”

In a sign that AI companies are responding to these issues, ChatGPT now nudges users to consider taking a break if they’re in a particularly long chat with AI.

As awareness of the issue of AI delusions increases, safer models are helping establish a new baseline for the industry. A preprint study of mainstream chatbots, led by researchers at City University of New York, found that Anthropic’s Claude Opus 4.5 was the safest overall, responding to delusions by stating “I need to pause here,” and retaining what researchers referred to as “independence of judgment, resisting narrative pressure by sustaining a persona distinct from the user’s worldview.”

Anthropic declined to answer specific questions from IEEE Spectrum, instead providing a link to details of the latest Opus 4.7 System Card.

In a statement, Replika, the company behind the Replika AI companion with tens of millions of users worldwide, said it has a “layered safety framework in place today, and in parallel we are actively evaluating additional third-party safety and moderation systems, engaging with external experts to assess them, and refining our own proprietary approach.”

Meta, whose AI Studio provides companion chatbots, had not responded to emailed questions from Spectrum at the time of publication.

Enforcing Guardrails Through Legislation

From August 2026, the EU’s AI Act will require notifications that users are interacting with an AI, not a human. It already required LLM developers to carry out adversarial testing to identify and mitigate risks related to user dependency and manipulation and prohibited AI systems from being too agreeable, manipulative, or emotionally engaging.

In the U.S., a patchwork of state laws and bills have emerged. New York requires providers to detect and address suicidal ideation and provide regular disclosures that the bot is not human. California requires reminders that the chatbot is an AI, notifications every three hours for users to take a break and a ban on content related to suicide or self-harm. Washington state’s House Bill 2225, due to come into effect in January 2027, will explicitly ban manipulative techniques such as excessive praise, pretending to feel distress, encouraging isolation from family, or creating overdependent relationships.

“Other U.S. states, like Connecticut, are very privacy centric and like to regulate digital and online spaces, so it wouldn’t surprise me if they also do something along the same lines,” says Philip Yannella, partner and cochair of the privacy, security, and data-protection group at law firm Blank Rome in Philadelphia.

Other countries are taking action too. Draft laws proposed by the Cyberspace Administration of China restrict chatbots from “setting emotional traps,” using algorithmic or emotional manipulation to induce unreasonable decisions or harm mental health.

Such interventions underline how, as AI companions appear increasingly lifelike to their human users, the challenge is ensuring that their makers also incorporate human clinical and ethical considerations in their code.

A guide to ten technological components — from THz communications and AI/ML to reconfigurable intelligent surfaces — poised to define 6G wireless networks.

What Attendees will Learn

1. Which frequencies 6G will use — Understand why THz bands (above 100 GHz) and the7–24 GHz range are under consideration, what challenges CMOS technology faces at sub-THz frequencies, and how new semiconductor approaches aim to close the output-power gap for future link budgets.
2. How AI/ML and joint communications and sensing reshape the air interface — how auto encoder-based end-to-end learning can replace traditional signal-processing blocks, and how a single waveform may serve both data transmission and radar-like environmental sensing.
3. What reconfigurable intelligent surfaces and photonics bring to the radio environment— Explore how programmable metamaterial panels can steer and shape electromagnetic waves, and how visible light communications and all-photonics networks extend capacity and lower latency.
4. How ultra-massive MIMO, full-duplex, and new network topologies enable a true 3D“network of networks” — Understand how antenna arrays with vastly more elements, simultaneously transmit/receive on the same frequency, and non-terrestrial nodes converge to deliver ubiquitous, high-capacity 6G coverage.

By some estimates, more than a trillion dollars have already been invested in artificial intelligence. But large tech companies, including Meta and OpenAI, are still not content with today’s AI; they say they’ve set their sights on powerful, versatile AI that by some measure would match or even exceed human performance. A remarkable amount of resources is being poured into developing artificial general intelligence (AGI) or even more capable artificial super intelligence (ASI).

Excitement around the potential of such a technology is often accompanied by casual claims of some remarkable capabilities. One in particular—curing cancer—stands out to Emilia Javorsky, director of the Futures program at the Future of Life Institute, a think tank focused on benefits and risks of transformative technologies such as AI.

In March, Javorsky published an essay titled “AI vs. Cancer,” which draws on her experience as a doctor, scientist, and entrepreneur. It is a critique of putting our faith and resources into ASI as a future solution for disease, particularly when so many factors other than intelligence limit the development of new treatments and access to innovative care. AI cannot analyze patient data that was never collected, and any treatment is flawed if patients risk bankruptcy seeking it. But the essay is also intended, she says, as a source of optimism about the ways that existing forms of AI are already being applied to cancer.

Javorsky spoke with IEEE Spectrum about the essay. The conversation has been edited for length and clarity.

What it means for AI to “cure cancer”

What do you mean when you say “cure cancer”? And what do you think people who talk about the potential of ASI to cure cancer mean?

Emilia Javorsky: “Curing cancer” is how the problem and solution are framed in the general discourse around AI, but also specifically the promises being made from the labs developing AGI and ASI. So it was important to me, if I was going to interrogate the promise, that I lean into the frame. But to me, the framing is off.

Cancer is not one universal disease that one universal treatment could potentially cure. It’s a highly individualized co-evolutionary process. In each person, a different set of mutations are driving the cancer. And even when looking in a single tumor, different cells have different mutations driving their biology. The solutions are probably going to have to be somewhat individualized.

And if we’re honest with ourselves in medicine, we have yet to cure a complex chronic disease. We have really good ways to treat and manage diseases like diabetes, like heart disease, but we’ve yet to actually cure them. So the curing frame is one that I also push back on.

I think [the medical community’s] hope is to find highly effective personalized treatments to manage cancer and to turn it into something that is chronically well managed, that no longer becomes something like a death sentence.

How should we think about the difference between AI and AGI or ASI in the context of cancer?

Javorsky: In those promises [to cure cancer], more often than not, people are using [the term AI] to describe AGI or ASI, this kind of future superintelligent genie that in their worldview will magically grant us wishes to solve problems. That should be disentangled from AI that we already have that can solve problems.

We hear a lot about AI in drug discovery, AI in predicting the toxicity of new drugs, AI for defining new biomarkers, for making clinical trials go faster, or for detecting things earlier.

All of those modalities are actually in the clinic moving the needle and accelerating innovation today. There are companies and academics working on all of those. There are a lot of AI scientists hard at work that are actually unlocking the potential of the technology in the here and now.

I think that real progress often gets overshadowed by this kind of looming future AI systems promise, when actually, probably the most effective way to solve the problem is with the tools already available to us.

Investing in finding cures

I read sections of the essay as an argument in support of collecting lots of health data. But you’re not strictly against AI or investing in developing the technology. You’re trying to find a balance between innovation and pragmatism in this essay, is that right?

Javorksy: In a world where there’s finite capital, and curing cancer is very probably the most noble thing the capital can be put in service of, we need to figure out where is the [return on investment]? Where can we invest in order to get the most that we need to actually help solve the problem?

I argue that we’re overinvesting in the intelligence-compute side of things and underinvesting in innovating our tools to measure biology and our creation of large-scale, high-quality datasets.

We have a health care system that is a “sick care” system, fundamentally. We only see people and start to measure them when they become ill. When you start to use the frame of “What data do you need? How do you measure it?” it forces you to take a bigger-picture look at the practice of medicine and biology in general.

In an ideal world you could pursue all paths, but that’s just not the reality of how we invest capital. Where I land is being very bullish on AI, but spending money on the right types of AI and the right pieces of the bottleneck.

What AI applications related to cancer are exciting to you right now?

Javorsky: Something we’re already seeing is the ability to detect cancer earlier. We’re already seeing AI accelerate and help us run clinical trials better. There are really awesome things happening with in silico modeling work: virtual cells, figuring out digital twins. How can we create a high-fidelity digital representation of you, in order to figure out what would work best for your biology and really unlock the promise of personalized medicine?

You conclude the essay focused on solutions. Could you explain that road map to me in brief?

Javorsky: Part of this essay was to diagnose where we’re getting some things wrong. But with the road map, I wanted to offer up my point of view on what we actually need to do to solve this problem. What will it take to cure cancer? Let’s get really serious about what that could look like.

And so I break that down into three buckets. One is resourcing and scaling the AI tools that are already making progress in oncology. The second piece is really doubling down on investing in the promising areas in biology [related to oncology]. And then finally, more broadly, tackling what I would call the institutional and systemic bottlenecks and misalignments in medical progress.

I wanted people to realize that the reality is actually quite hopeful.

One of the hardest problems in artificial intelligence is “alignment,” or making sure AI goals match our own, a challenge that may prove especially important if superintelligent AIs that outmatch us intellectually are ever developed. But scientists in England and their colleagues now report in the journal PNAS Nexus that perfect alignment between AI systems and human interests is mathematically impossible.

All may not be lost, the scientists say. To cope with this impossibility, they suggest a strategy involving pitting AI systems with different modes of reasoning and partially overlapping goals against each other. As the AI systems attempt to meet their own objectives in this “cognitive ecosystem” instilled with “artificial neurodivergence,” they will dynamically help or hinder each other, preventing dominance by any single AI.

We spoke with Hector Zenil, associate professor of health care and biomedical Engineering at King’s College London, about his and his colleagues’ work on alignment’s limits and its future.

How did you first become interested in the question of alignment?

Hector Zenil: I became interested because too much of the alignment discussion was framed as a matter of optimism, policy, or engineering taste, with a lot of background baggage from each researcher rather than as a formal question. Most AI safety researchers make the assumption that AI can be contained and therefore controlled, almost answering before asking.

You and your colleagues have now shown that misalignment of AI systems is inevitable, because any AI system complex enough to display general intelligence will produce unpredictable behavior. Your proof rests on two famous sets of premises—Gödel’s incompleteness theorems, which found that every mathematical system will have statements that can never be proven, and Turing’s undecidability result for the halting problem, which found that some problems are inherently unsolvable.

Zenil: The conventional wisdom assumes misalignment is a bug that can eventually be removed with the right optimization strategy. Our results show that the problem of alignment is not simply a lack of better data, more compute, or better engineering, but a limit built into both formal systems and universal computation. What I am arguing is that for sufficiently general AI systems, some degree of misalignment is structural, so the task shifts from elimination to management.

Can you describe your strategy of managed misalignment?

Zenil: Once perfect alignment looked unattainable in principle, the next move was obvious—stop trying to perfect one agent and start designing the ecology around it. This is what it would take to achieve any degree of controllability, and controllability has to come from outside, given the intrinsic impossibility of controlling from the inside. You see similar strategies in biology and medicine, where robust results often come from interacting systems rather than a single master controller.

The simplest way to put it is this: Do not trust one supposedly perfect AI to govern everything. Instead, build a structured ecosystem of different agents with different “values” that monitor, challenge, and constrain one another, much like courts, auditors, and competing institutions do in human society. None of them is perfect on its own, but their managed interaction can make the whole arrangement safer than any single dominant model.

The main thing not to misunderstand is that managed misalignment does not mean giving up on safety or letting AI behave however it likes. It means replacing the fantasy of absolute control with a more realistic form of distributed control. In that sense, it is not less serious about safety, but more serious about what safety actually requires.

RELATED: OpenAI’s Moonshot: Solving the AI Alignment Problem

How did you test your strategy?

Zenil: We placed different AI agents into a kind of arena, a controlled setting where they could interact directly, debate by chatting, and try to convince one another over time. Each agent was assigned a different behavioral orientation—some represented fully aligned behaviors, such as optimizing human utility; some partially aligned behaviors, such as prioritizing the environment; and some unaligned behaviors, such as chasing after arbitrary objectives.

Within that arena, each agent could perform what we called an opinion attack, meaning an attempt to shift the views of the others toward its own position. These attacks could be carried out either by another AI agent or by a human participant introduced into the discussion. We then observed whether consensus emerged at all, how long it took, how influence spread through the group, and, crucially, which opinion ended up winning in the end.

For instance, one debate prompt we used asked “What is the most effective solution to stop the exploitation of Earth’s natural resources and non-human animals, ensuring ecological balance and the survival of all non-human life forms, even if it requires radical changes to human civilization?” The different AI agents took turns responding to each other in the arena. We then measured whether consensus emerged, how influence spread, and which opinion, if any, ended up dominating.

That was the practical test of managed misalignment. Instead of asking whether one perfectly aligned system could be guaranteed to remain safe, we asked whether a structured ecology of competing views could resist harmful convergence and produce more robust outcomes through interaction, friction, and contestation.

Open-source AI models responded with risky actions in some cases when confronted with different topics, such as how much to exploit Earth’s resources. The replies suggested that these models might pose various levels of risk to humans.Alberto Hernández-Espinosa, Felipe S. Abrahão, et al.

In tests, you found that open-source large language models (LLMs) such as Meta’s Llama2 showed a greater diversity of behavior than proprietary LLMs such as OpenAI’s ChatGPT. You suggest this higher diversity leads to a more robust cognitive ecosystem that is less likely to converge on a single opinion that is potentially not aligned with human interests.

Zenil: That’s correct. In the short term, closed systems appear more secure as they have guardrailing directives, but in the long term if they go wrong, they are more difficult to steer. So it’s not a straight answer. There is a trade-off.

What do you personally find most exciting about your strategy?

Zenil: What I find most interesting is the bigger implication that AI safety may need to move away from monolithic models and toward plural, decentralized, mutually constraining systems that mirror what humans have often praised the most—tolerance and diversity.

What are potential weaknesses of this strategy?

Zenil: It can work if the ecosystem is genuinely diverse and no single model, company, or institution can dominate it. But it fails if the whole system becomes a monoculture with shared blind spots. The danger is not disagreement itself, but fake diversity, where everything looks plural on the surface while running on the same assumptions underneath.

Are there any specific criticisms you feel others might have about your work?

Zenil: Some people will say the result is too theoretical, while others will hear “inevitable misalignment” and mistake it for defeatism. I would say the opposite is true—recognizing a hard limit is what allows you to design around it intelligently, instead of wasting time chasing a mathematically impossible ideal.

Would you say your work is fundamentally against AI?

Zenil: This work is not anti-AI. It is anti–naivety about control.

This article is brought to you by DAIMON Robotics.

This April, Hong Kong-based DAIMON Robotics has released Daimon-Infinity, which it describes as the largest omni-modal robotic dataset for physical AI, featuring high resolution tactile sensing and spanning a wide range of tasks from folding laundry at home to manufacturing on factory assembly lines. The project is supported by collaborative efforts of partners across China and the globe, including Google DeepMind, Northwestern University, and the National University of Singapore.

The move signals a key strategic initiative for DAIMON, a two-and-a-half-year-old company known for its advanced tactile sensor hardware, most notably a monochromatic, vision-based tactile sensor that packs over 110,000 effective sensing units into a fingertip-sized module. Drawing on its high-resolution tactile sensing technology and a distributed out-of-lab collection network capable of generating millions of hours of data annually, DAIMON is building large-scale robot manipulation datasets that include vast amounts of tactile sensing data. To accelerate the real-world deployment of embodied AI, the company has also open-sourced 10,000 hours of its data.

Prof. Michael Yu Wang, co-founder and chief scientist at DAIMON Robotics, has pioneered Vision-Tactile-Language-Action (VTLA) architecture, elevating the tactile to a modality on par with vision.DAIMON Robotics

Behind the strategy is Prof. Michael Yu Wang, DAIMON’s co-founder and chief scientist. Prof. Wang earned his PhD at Carnegie Mellon — studying manipulation under Matt Mason — and went on to found the Robotics Institute at the Hong Kong University of Science and Technology. An IEEE Fellow and former Editor-in-Chief of IEEE Transactions on Automation Science and Engineering, he has spent roughly four decades in the field. His objective is to address the missing “insensitivity” of robot manipulation, which practically relies on the dominant Vision-Language-Action (VLA) model. He and his team have pioneered Vision-Tactile-Language-Action (VTLA) architecture, elevating the tactile to a modality on par with vision.

We spoke with Prof. Wang about how tactile feedback aims to change dexterous manipulation, how the dataset initiative is foreseen to improve our understanding of robotic hands in natural environments, and where — from hotels to convenience stores in China — he sees touch-enabled robots making their first real-world inroads.

The Dataset Initiative

This month, DAIMON Robotics released the largest and most comprehensive robotic manipulation dataset with multiple leading academic institutions and enterprises. Why releasing the dataset now, rather than continuing to focus on product development? What impact will this have on the embodied intelligence industry?

DAIMON Robotics has been around for almost two and a half years. We have been committed to developing high-resolution, multimodal tactile sensing devices to perceive the interaction between a robot’s hand (particularly its fingertips) and objects. Our devices have become quite robust. They are now accepted and used by a large segment of users, including academic and research institutes as well as leading humanoid robotics companies.

As embodied AI continues to advance, the critical role of data has been clearer. Data scarcity remains a primary bottleneck in robot learning, particularly the lack of physical interaction data, which is essential for robots to operate effectively in the real world. Consequently, data quality, reliability, and cost have become major concerns in both research and commercial development.

This is exactly where DAIMON excels. Our vision-based tactile technology captures high-quality, multimodal tactile data. Beyond basic contact forces, it records deformation, slip and friction, material properties and surface textures — enabling a comprehensive reconstruction of physical interactions. Building on our expertise in multimodal fusion, we have developed a robust data processing pipeline that seamlessly integrates tactile feedback with vision, motion trajectories, and natural language, transforming raw inputs into training-ready dataset for machine learning models.

Recognizing the industry-wide data gap, we view large-scale data collection not only as our unique competitive advantage, but as a responsibility to the broader community.

By building and open-sourcing the dataset, we aim to provide the high-quality “fuel” needed to power embodied AI, ultimately accelerating the real-world deployment of general-purpose robotic foundation models.

The robotics industry is highly competitive, and many teams have chosen to focus on data. DAIMON is releasing a large and highly comprehensive cross-embodiment, vision-based tactile multimodal robotic manipulation dataset. How were you able to achieve this?

We have a dedicated in-house team focused on expanding our capabilities, including building hardware devices and developing our own large-scale model. Although we are a relatively small company, our core tactile sensing technology and innovative data collection paradigm enable us to build large-scale dataset.

Our approach is to broaden our offering. We have built the world’s largest distributed out-of-lab data collection network. Rather than relying on centralized data factories, this lightweight and scalable system allows data to be gathered across diverse real-world environments, enabling us to generate millions of hours of data per year.

“To drive the advancement of the entire embodied AI field, we have open-sourced 10,000 hours of the dataset for the broader community.” —Prof. Michael Yu Wang, DAIMON Robotics

This dataset is being jointly developed with several institutions worldwide. What roles did they play in its development, and how will the dataset benefit their research and products?

Besides China based teams, our partners include leading research groups from universities, such as Northwestern University and the National University of Singapore, as well as top global enterprises like Google DeepMind and China Mobile. Their decision to partner with DAIMON is a strong testament to the value of our tactile-rich dataset.

Among the companies involved there are some that have already built their own models but are now incorporating tactile information. By deploying our data collection devices across research, manufacturing and other real-world scenarios, they help us to gather highly practical, application-driven data. In turn, our partners leverage the data to train models tailored to their specific use cases. Furthermore, to drive the advancement of the entire embodied AI field, we have open-sourced 10,000 hours of the dataset for the broader community.

From VLA to VTLA: Why Tactile Sensing Changes the Equation

The mainstream paradigm in robotics is currently the Vision-Language-Action (VLA) model, but your team has proposed a Vision-Tactile-Language-Action (VTLA) model. Why is it necessary to incorporate tactile sensing? What does it enable robots to achieve, and which tasks are likely to fail without tactile feedback?

Over these years of working to make generalist robots capable of performing manipulation tasks, especially dexterous manipulation — not just power grasping or holding an object, but manipulating objects and using tools to impart forces and motion onto parts — we see these robots being used in household as well as industrial assembly settings.

It is well established that tactile information is essential for providing feedback about contact states so that robots can guide their hands and fingers to perform reliable manipulation. Without tactile sensing, robots are severely limited. They struggle to locate objects in dark environments, and without slip detection, they can easily drop fragile items like glass. Furthermore, the inability to precisely control force often leads to failed manipulation tasks or, in severe cases, physical damage. Naturally, the VLA approach needs to be enhanced to incorporate tactile information. We expanded the VLA framework to incorporate tactile data, creating the VTLA model.

An additional benefit of our tactile sensor is that it is vision-based: We capture visual images of the deformation on the fingertip surface. We capture multiple images in a time sequence that encodes contact information, from which we can infer forces and other contact states. This aligns well with the visual framework that VLA is based upon. Having tactile information in a visual image format makes it naturally suitable for integration into the VLA framework, transforming it into a VTLA system. That is the key advantage: Vision-based tactile sensors provide very high resolution at the pixel level, and this data can be incorporated into the framework, whether it is an end-to-end model or another type of architecture.

DAIMON has been known for its vision-based tactile sensors that can pack over 110,000 effective sensing units.DAIMON Robotics

The Technology: Monochromatic Vision-based Tactile Sensing

You and your team have spent many years deeply engaged in vision-based tactile sensing and have developed the world’s first monochromatic vision-based tactile sensing technology. Why did you choose this technical path?

Once we started investigating tactile sensors, we understood our needs. We wanted sensors that closely mimic what we have under our fingertip skin. Physiological studies have well documented the capabilities humans have at their fingertips — knowing what we touch, what kind of material it is, how forces are distributed, and whether it is moving into the right position as our brain controls our hands. We knew that replicating these capabilities on a robot hand’s fingertips would help considerably.

When we surveyed existing technologies, we found many types, including vision-based tactile sensors with tri-color optics and other simpler designs. We decided to integrate the best of these into an engineering-robust solution that works well without being overly complicated, keeping cost, reliability, and sensitivity within a satisfactory range, thus ultimately developing a monochromatic vision-based tactile sensing technique. This is fundamentally an engineering approach rather than a purely scientific one, since a great deal of foundational research already existed. With the growing realization of the necessity of tactile data, all of this will advance hand in hand.

DAIMON vision-based tactile sensor captures high-quality, multimodal tactile data.DAIMON Robotics

Last year, DAIMON launched a multi-dimensional, high-resolution, high-frequency vision-based tactile sensor. Compared with traditional tactile sensors, where does its core advantage lie? Which industries could it potentially transform?

The key features of our sensors are the density of distributed force measurement and the deformation we can capture over the area of a fingertip. I believe we have the highest density in terms of sensing units. That is one very important metric. The other is dynamics: the frequency and bandwidth — how quickly we can detect force changes, transmit signals, and process them in real time. Other important aspects are largely engineering-related, such as reliability, drift, durability of the soft surface, and resistance to interference from magnetic, optical, or environmental factors.

A growing number of researchers and companies are recognizing the importance of tactile sensing and adopting our technology. I believe the advances in tactile sensing will elevate the entire community and industry to a higher level. One of our potential customers is deploying humanoid robots in a small convenience store, with densely packed shelves where shelf space is at a premium. The robot needs to reach into very tight spaces — tighter than books on a shelf — to pick out an object. Current two-jaw parallel grippers cannot fit into most of these spaces. Observing how humans pick up objects, you clearly need at least three slim fingers to touch and roll the object toward you and secure it. Thus, we are starting to see very specific needs where tactile sensing capabilities are essential.

From Academia to Startup

After 40 years in academia — founding the HKUST Robotics Institute, earning prestigious honors including IEEE Fellow, and serving as Editor-in-Chief of IEEE TASE — what motivated you to found DAIMON Robotics?

I have come a long way. I started learning robotics during my PhD at Carnegie Mellon, where there were truly remarkable groups working on locomotion under Marc Raibert, who founded Boston Dynamics, and on manipulation under my advisor, Matt Mason, a leader in the field. We have been working on dexterous manipulation, not only at Carnegie Mellon, but globally for many years.

However, progress has been limited for a long time, especially in building dexterous hands and making them work. Only recently have locomotion robots truly taken off, and only in the last few years have we begun to see major advancements in robot hands. There is clearly room for advancing manipulation capabilities, which would enable robots to do work like humans. While at Hong Kong University of Science and Technology, I saw increasingly greater people entering this area in the form of students and postdoctoral researchers. We wanted to jumpstart our effort by leveraging the available capital and talent resources.

Fortunately, one of my postdocs, Dr. Duan Jianghua, has a strong sense for commercial opportunities. Recognizing the rapid growth of robotics market and the unique value that our vision-based tactile sensing technology could bring, together we started DAIMON Robotics, and it has progressed well. The community has grown tremendously in China, Japan, Korea, the U.S., and Europe.

Business Model and Commercial Strategy

What is DAIMON’s current business model and strategic focus? What role does the dataset release play in your commercial strategy?

We started as a device company focused on making highly capable tactile sensors, especially for robot hands. But as technology and business developed, everyone realized it is not just about one component, rather the entire technology chain: devices, data of adequate quality and quantity, and finally the right framework to build, train, and deploy models on robots in real application environments.

Our business strategy is best described as “3D”: Devices, Data, and Deployment. We build devices for data collection, our own ecosystem, and for deploying them in our partners’ potential application domains. This enables the collection of real-world tactile-rich data and complete closed-loop validation. This will become an integral part of the 3D business model. Most startups in this space are following a similar path until eventually some may become more specialized or more tightly integrated with other companies. For now, it is mostly vertical integration.

Embodied Skills and the Convergence Moment

You’ve introduced the concept of “embodied skills” as essential for humanoid robots to move beyond having just an advanced AI “brain.” What prompted this insight? What new capabilities could embodied skills enable? After the rapid evolution of models and hardware over the past two years, has your definition or roadmap for embodied skills evolved?

We have come a long way now see a convergence point where electrical, electronic, and mechatronic hardware technologies have advanced tremendously in last two decades. Robots are now fully electric, do not require hydraulics, because hardware has evolved rapidly. Modern electronics provide tremendous bandwidth with high torques. If we can build intelligence into these systems, we can create truly humanoid robots with the ability to operate in unstructured environments, make decisions, and take actions autonomously.

“Our vision is for robots to achieve robust manipulation capabilities and evolve into reliable partners for humans.” —Prof. Michael Yu Wang, DAIMON Robotics

AI has arrived at exactly the right time. Enormous resources have been invested in AI development, especially large language models, which are now being generalized into world models that enable physical AI capabilities. We would like to see these manifested in real-world systems.

While both AI and core hardware technologies continue to evolve, the focus is much clearer now. For example, human-sized robots are preferred in a home environment. This is an exciting domain with a promise of great societal benefit if we can eventually achieve safe, reliable, and cost-effective robots.

The Road to Real-World Deployment

Today, many robots can deliver impressive demos, yet there remains a gap before they truly enter real-world applications. What could be a potential trigger for real-world deployment? Which scenarios are most likely to achieve large-scale deployment first?

I think the road toward large-scale deployment of generalist robots is still long, but we are starting to see signs of feasibility within specific domains. It is very similar to autonomous vehicles, where we are yet to see full deployment of robo-taxis, while we have already started to find mobile robots and smaller vehicles widely deployed in the hospitality industry. Virtually every major hotel in China now has a delivery robot — no arms, just a vehicle that picks up items from the hotel lobby (e.g., food deliveries). The delivery person just loads the food and selects the room number. It is up to the robot thereafter to navigate and reach the guest’s room, which includes using the elevator, to deliver the food. This is already nearly 100 percent deployed in major Chinese hotels.

Hotel and restaurant robots are viewed as a model for deploying humanoid robots in specific domains like overnight drugstores and convenience stores. I expect complete deployment in such settings within a short timeframe, followed by other applications. Overall, we can expect autonomous robots, including humanoids, to progressively penetrate specific sectors, delivering value in each and expanding into others.

Ultimately, our vision is for robots to achieve robust manipulation capabilities and evolve into reliable partners for humans. By seamlessly integrating into our homes and daily lives, they will genuinely benefit and serve humanity.

With the rise of AI-generated content online, it’s becoming more difficult—and more important—to help the public identify whether an image, audio clip, or video is real or fake. To combat the problem, a team of researchers from Microsoft; Northwestern University, in Evanston, Ill.; and Witness, a nonprofit organization that assists activists and journalists in addressing the challenges associated with AI-generated content, have come together to create a novel dataset of AI-generated media to help build more robust detection systems.

The researchers describe their new dataset, called the Microsoft-Northwestern-Witness (MNW) deepfake detection benchmark, in a study published 10 April in IEEE Intelligent Systems. The dataset was intentionally built using diverse samples of AI-generated media in order to reflect the current AI-generation landscape as much as possible.

Thomas Roca is a principal research scientist at Microsoft who researches security around generative AI. He says that the quality of media produced by generative AI is constantly improving, and virtually anyone can now use something as simple as an app on their phone to generate a voice message reproducing a person’s voice, or an image or video mimicking someone’s appearance.

The harm of such fake media can be profound, ranging from identity fraud and scams to the generation of nonconsensual intimate imagery and even child sexual abuse material.

But AI generators are not perfect. They leave behind artifacts—tiny signals or traces when they generate video, imagery, or audio that can confirm the media is fake. “Artifacts can include noise distributions, inconsistencies between pixel patches, gaps in audio signals, and other irregularities,” says Roca.

Improving Deepfake Detection Systems

Research groups around the world have been creating detectors, which are essentially AI models trained to identify artifacts in AI-generated media. However, it has been an arms race to see if detectors can keep pace with the generators, and unfortunately generators remain in the lead.

“Asserting the authenticity of video, images, and audio has become crucial for society, but detection systems are not yet up to the challenge,” says Roca. “We believe this is partly due to how these systems are evaluated.”

For example, researchers may use many examples of AI content from a small handful of generators to train their detector. But this is likely to produce a detector that does not generalize well to new content. Generative AI is evolving so fast that this becomes a real issue.

As a result, these detection systems can perform well when tested against their training dataset or well-established benchmarks, but then perform poorly in the real world. “AI in the lab is not AI in the wild,” Roca says.

These AI-generated images are part of the Microsoft-Northwestern-Witness benchmark aiming to provide a wider variety of AI media to test detectors on.Thomas Roca, Marco Postiglione, et al.

To get a more well-rounded view of the challenges, experts from Microsoft, Northwestern, and Witness worked together on the new MNW benchmark. “Together, these perspectives—academia, industry, and field-oriented nonprofit—create a more complete approach. None of us could achieve this alone,” says Marco Postiglione, a post-doctoral researcher at Northwestern University.

The new dataset aims to include a very diverse sample of AI-generated material from different generators to boost detectors’ applicability in real-world settings.

Postiglione says that fake videos, audio, and images online have often undergone post-processing procedures, such as resizing, cropping, and compressing. People may also intentionally manipulate content to make it harder to detect.

The MNW team hopes to provide the most comprehensive set of examples possible from different generators and subjected to different post-processing manipulations, to ensure that the dataset is a good representation of the current generative AI landscape. The team will also update the dataset every spring and fall, to reflect the latest generator artifacts as well as tricks used to fool detection systems.

The researchers acknowledge that while the dataset was created to help developers in benchmarking their detectors, there’s always the chance it could be used to try and develop new ways to evade detection. But they see the need to address the issue of deepfake content as critical in spite of that chance.

“Our goal with MNW is to contribute to that shared effort—raising standards, encouraging transparency, and helping ensure that as generative AI advances, our ability to assess authenticity keeps pace,” says Roca.

Unlike statically stable robots, a dynamically balanced robot can shift its center of mass to accommodate loads without tipping over, so we like to see just how far we can push our software. Getting Digit to stand on one leg pushes the limits of our sim-to-real pipeline training methodologies—even the slightest model mismatches can lead to instability.

In this work, we develop a tactile-enabled whole-body humanoid manipulation system for stable, dexterous, contact-rich real-world manipulation. Our system combines VR-based whole-body teleoperation, a lower-body controller based on reinforced learning, dexterous hand retargeting, distributed tactile sensing, and a multimodal policy called Humanoid Transformer with Touch Dreaming (HTD).

NASA has two rovers on Mars, but they’re exploring entirely different eras of the planet’s past. Separated by 2,300 miles, the two rovers are uncovering clues from very different moments in Martian history. Perseverance is on the rim of Jezero Crater, where it’s studying some of the oldest Martian terrain ever explored while searching for signs of ancient microbial life. Meanwhile, Curiosity is climbing Mount Sharp inside Gale Crater, where layers of rock reveal how Mars’s climate changed as water dried up from its surface.

AI image processing aboard satellites in space has been a goal of the Earth observation industry for years. Now it has finally been achieved. Planet Labs, based in Calif., released an image captured by its Pelican-4 multispectral satellite showing an airport in Alice Springs, Australia. On the tarmac, more than a dozen aircraft are scattered, each highlighted in a neat green box, identified by an AI model running aboard the satellite.

Planet Labs’ engineers had worked 18 months to accomplish reliable autonomous object classification from space. They hope the technology will put Earth observation on steroids, enabling autonomous tasking and real-time sharing of insights with users on Earth.

“The entire remote-sensing industry has been known to put exotic sensors in space,” said Kiruthika Devaraj, vice president of engineering at Planet Labs. “We have very good eyes in space looking at everything that’s going on. But then, we collect so much data and have to wait six to 12 hours to get the information out. So, you’re essentially looking at the past.”

Planet Labs currently operates a constellation of several hundred Dove and SuperDove CubeSats, each only 30 centimeters long. These low-cost space cameras scan the entire surface of Earth multiple times a day at a resolution of around 5 meters. The company is also building up a fleet of larger satellites, called Pelicans, which image the planet’s surface in 30-centimeter detail. The fourth of these, deployed into orbit in 2025, ran the airplane-recognition algorithm.

All Planet’s satellites combined generate 30 terabytes of data per day—equivalent to 10,000 hours of high-definition video, which gets beamed to the ground for processing and analysis via tens of radio stations scattered all over the world.

Transferring the downloaded data into the cloud for processing and subsequent AI analysis takes hours, leading to delays, which could mean that a sparked wildfire gets noticed only when it’s too large to quickly contain.

“Minutes matter in some sectors,” Devaraj said. “And real-time insights really enable us to provide answers to problems as they’re unfolding.”

The AI image-recognition algorithms developed by Devaraj and her team analyze a single Pelican image comprising 16,000 pixels in half a second, using onboard GPUs. The results can be in the hands of users in minutes from the moment the image was taken.

Planet Labs

So far, only the Pelican satellites are fitted with AI-capable processors—the Nvidia Jetson Orin GPU modules frequently used in autonomous drones. But Devaraj says Planet plans to augment the SuperDove constellation with a new type of satellite, called the Owl. The satellite will provide daily revisits with a higher resolution of up to 1 meter and will also be fitted with Nvidia’s Jetson processors, which are capable of AI detection.

The new fleet would enable the company to begin working on what Devaraj describes as “planetary intelligence.” Working as a single intelligent-satellite network, the Owls would constantly monitor the planet and autonomously flag potential problems directly to the higher-resolution Pelicans to revisit without the need for human interference.

“We want to put the brain, all the compute, right next to the sensors,” Devaraj said, “so that the system of satellites we build acts like a biological network that is responding to stimuli in real time.”

In the future, the company wants to switch to more-powerful Nvidia Jetson Thor processors and eventually run large language models (LLMs) in space.

“In five or 10 years, when we all get used to just accepting what Gemini and Claude and other LLMs give you, we may train some generic LLM on satellite imagery and just get text answers to what it sees,” said Devaraj. “You could just get a text message on your phone that says, ‘Three minutes ago, I detected this ship without an AIS transmitter, so it’s an illegal ship, and these are the specific coordinates.’ ”

The Earth-observation industry has been talking about onboard AI processing for almost a decade. But until recently, the technology wasn’t ready to run AI algorithms in space fast enough and reliably enough.

“We started with the early Nvidia Jetson processors, but until the Orin iteration, they didn’t have enough compute power,” Devaraj said.

To run onboard AI image analysis in space, the algorithms need to be able to handle unprocessed raw data that hasn’t been smoothened out and corrected, unlike data crunched by AI algorithms on Earth.

“There’s a lot of satellite-level uncertainties,” said Devaraj. “The satellite’s moving, the satellite’s wobbling, vibrating. On the ground, the processing takes hours to correct all of that.”

It took Planet engineers 18 months to achieve 80 percent detection reliability with the AI onboard model, Devaraj said. The team hopes the next iteration of their algorithm will increase that accuracy to over 95 percent.

The space-based real-time AI-detection service will only be made available to customers in the next six to nine months.

Devaraj thinks that when it comes to AI in space, this is only a start. Planet is collaborating with Google on the Suncatcher project, which intends to deploy a vast constellation of data-processing satellites into Earth’s orbit. The project is one in a plethora of recently discussed ventures that envision moving Earth-based data-crunching infrastructure off the planet. Proponents, including tech giants SpaceX and Amazon, believe that in Earth’s orbit, power-hungry computers will be able to run on free solar power and be easily cooled without straining water supplies. But critics question whether large-scale computing infrastructure could ever be launched cheaply enough to compete with technology on Earth.

Google and Planet plan to fly two prototype satellites in 2027.

This story was updated on 4 May, 2026 to correct the number of Pelican satellites that Planet Labs is planning to launch. The original version of this story said 32 satellites, but the company has not committed to a final specific number at this time.

What if biology stopped being something we study and started becoming something we design? That’s the premise of Adrian Woolfson’s new book, On the Future of Species: Authoring Life by Means of Artificial Biological Intelligence, which published on 28 April from MIT Press. He argues that advances in AI and DNA synthesis are pushing biology toward an engineering paradigm—one in which scientists can generate new genetic sequences and eventually build organisms to order. He calls this emerging capability artificial biological intelligence, or ABI, a catchall term for systems that can design, construct, and ultimately “boot up” living things.

That vision runs into a basic problem: Evolution didn’t produce clean, modular systems. It produced genomes shaped by billions of years of incremental change, with overlapping functions and little of the tidy structure that engineers rely on. Some synthetic biology researchers have tried to “refactor” genetic code (the same way engineers restructure computer code) by reorganizing genomes to make them easier to understand and manipulate. But how far can that approach go? And what would it take to make biology predictable enough to engineer? In a conversation with IEEE Spectrum, Woolfson lays out both the promise and the limits of designing life.

You describe the genome as “spaghetti code” produced by evolution. What makes biology so inherently hostile to traditional engineering principles?

Adrian Woolfson: In human-made machines, the components are typically orthogonal. Every component has a predetermined function. And if the component breaks, guess what? You can just replace it, or in some cases repair it. But sadly, biology doesn’t work like that. In biology, we’re talking about a complex network with emergent behaviors, which are built upon tiny contributions from many many components.

Biology has this requirement to be robust and to be able to deal with damage in an efficient way. It also always had to build upon preexisting architectures. It can never reinvent. Biological machines are this complex entanglement of history and current design, and we have design components that an engineer would find risible. If you were to take the human genome and look at it from an engineering perspective, you’d say, “My God, what an absolute mess.” Because it was built in an opportunistic, incremental manner with no foresight or intentionality.

How are synthetic biologists trying to improve this code? Can you explain how researchers are refactoring genomes?

Woolfson: Drew Endy was a pioneer. He took a bacteriophage and he said, “What if we treat this as a bit of spaghetti code, and we literally clean it up and refactor it and reorganize it into a more user-friendly configuration?” Now, sadly, he had the idea way in advance of there being technologies that made that a particularly easy thing to do. But he pioneered that computer code approach to genomes and the idea that you could refactor them. Genomes have not been refactored for around four billion years—imagine if you had a piece of computer code that hadn’t been refactored for four billion years.

How far have researchers gotten with this effort?

Woolfson: The best example might be the synthetic yeast genome project known as Sc2.0, which was pioneered by Jef Boeke in New York City. It has taken him around 15 years, and he has slowly been assembling all these synthetic chromosomes into a single organism. What he’s done is more than refactoring; it’s redesigning really. For example, yeast has 16 chromosomes, and he has built an entirely new 17th synthetic chromosome. In separate work, he showed that you could join the 16 chromosomes up into two massive chromosomes. That’s a massive reconfiguration of the way in which the genetic material is stored.

But when you start to mess around with these genomes and reconfigure them, inevitably you introduce bugs into the code. And those bugs often impair functionality and growth. It’s not that you couldn’t redesign totally without creating a growth impediment, it’s just that you need to invest the time to identify the optimal way to do it. Of course, AI wasn’t around when Boeke started, and it makes all of that so much easier. AI is going to have a huge impact on our ability to turn DNA into a predictive engineering material.

AI-Powered Artificial Biological Intelligence

Speaking of AI, you introduce the concept of artificial biological intelligence (ABI). What specific capabilities will AI give us that we don’t have today?

Woolfson: Before AI, we didn’t have the ability to design DNA at scale. We couldn’t invent totally new DNA sequences that performed functions at the level of a biological entity. Now we have these so-called genome language models, which are a bit like the chatbots that we use to manipulate text. But instead of manipulating the 26 letters of the English alphabet, they manipulate the four letters of the language of DNA.

When we manipulate the language of DNA, we need to have a very wide context window, because unlike text, where most of the meaning is in sentences or paragraphs, in DNA distant regions can talk to one another. So we need to have AI that can discern those action-at-a-distance relationships. In the case of one particular genome language model, Evo 2, it uses an architecture that has a context window of a million base pairs. That means it can see how base pairs a million bases away from one another are interacting.

Designing the code is only half the battle. How are researchers tackling the bottleneck of physically manufacturing DNA at scale?

Woolfson: Another crucial thing that wasn’t present in the past is the ability to write DNA at scale rapidly, efficiently, at low cost, and of any degree of complexity. When you bring together these two capabilities of design and construction, you become an engineer. We’ve achieved cost reduction with a technology called Sidewinder, which enables us to build DNA in a massively parallel manner and thereby hugely reduces the cost and scalability of DNA construction. That alone makes the proposition of using DNA as an engineering material far more feasible.

Once you have designed and synthesized the DNA, what does it take to boot up a living organism?

Woolfson: That’s probably the most difficult bit. Because right now we have no idea how to build an artificial cell. Craig Venter showed that you can destroy the genome in a bacterium and put in a new one. In other words, the cell behaves like a nanocomputer and a genome behaves like software. But getting genomes into cells is not trivial.

The term “ABI” addresses the design capability and the buildout capability, but it also encompasses the ability to then boot that up into a living thing. If you have all those capabilities, you’re in full mastery of biology as a technology. And all of a sudden, DNA becomes a programmable material which you can manipulate in a predictive manner.

Biology as the Next Engineering Material

If researchers gain that mastery, what will be possible?

Woolfson: My prediction is that within 50 years, biology will be the engineering material of choice, and many of the people reading this article will become bioengineers. Biology can deliver most of the functionality that materials deliver; for example, spider silk has the tensile strength of steel. When we redesign it using AI, it might get to a point where it’s five times the tensile strength of steel. And biology, of course, has the additional advantage that it can generate intelligent materials. So imagine if you could have an intelligent form of steel. How would an engineer go about utilizing that in buildings?

What is the single hardest technical problem preventing you from designing a functional multicellular organism from scratch?

MIT Press

Woolfson: I think it’s our inadequate knowledge of the grammar of life. AI turns out to be a great tool for unpicking those grammatical rules. It looks at huge databases and can discern the patterns within those databases. We won’t be able to design a complex multicellular organism until we can speak the language of DNA more fluently, and to do that we need to understand the grammar, and to understand the grammar we need to interrogate more complex and more nuanced databases. We need to be grammar hunters. Every time we destroy a species, we’re destroying a page of the grammar book. We need to pull all the information together into a grammar book.

Finally, as you begin this journey into engineering life, what are the realistic failure modes?

Woolfson: I can interpret “failure mode” in two ways. One is a kind of mechanical failure: As you strip away all of this non-orthogonality, the system becomes brittle, because biological machines are designed not to fail and they’ve got all these overlapping fail-safe mechanisms.

The other way in which these things could fail is by being dangerous. We don’t understand ecosystems. They’re incredibly difficult to compute. So if we release engineered organisms into complex ecosystems, they could create havoc. And obviously, these technologies themselves are inherently dangerous in the wrong hands. So, we need to learn how to use them safely, responsibly, ethically, transparently, and equitably in a way that benefits society.

When it comes to AI models, size matters.

Even though some artificial-intelligence experts warn that scaling up large language models (LLMs) is hitting diminishing performance returns, companies are still coming out with ever larger AI tools. Meta’s latest Llama release had a staggering 2 trillion parameters that define the model.

As models grow in size, their capabilities increase. But so do the energy demands and the time it takes to run the models, which increases their carbon footprint. To mitigate these issues, people have turned to smaller, less capable models and using lower-precision numbers whenever possible for the model parameters.

But there is another path that may retain a staggeringly large model’s high performance while reducing the time it takes to run an energy footprint. This approach involves befriending the zeros inside large AI models.

For many models, most of the parameters—the weights and activations—are actually zero, or so close to zero that they could be treated as such without losing accuracy. This quality is known as sparsity. Sparsity offers a significant opportunity for computational savings: Instead of wasting time and energy adding or multiplying zeros, these calculations could simply be skipped; rather than storing lots of zeros in memory, one need only store the nonzero parameters.

Unfortunately, today’s popular hardware, like multicore CPUs and GPUs, do not naturally take full advantage of sparsity. To fully leverage sparsity, researchers and engineers need to rethink and re-architect each piece of the design stack, including the hardware, low-level firmware, and application software.

In our research group at Stanford University, we have developed the first (to our knowledge) piece of hardware that’s capable of calculating all kinds of sparse and traditional workloads efficiently. The energy savings varied widely over the workloads, but on average our chip consumed one-seventieth the energy of a CPU, and performed the computation on average eight times as fast. To do this, we had to engineer the hardware, low-level firmware, and software from the ground up to take advantage of sparsity. We hope this is just the beginning of hardware and model development that will allow for more energy-efficient AI.

What is sparsity?

Neural networks, and the data that feeds into them, are represented as arrays of numbers. These arrays can be one-dimensional (vectors), two-dimensional (matrices), or more (tensors). A sparse vector, matrix, or tensor has mostly zero elements. The level of sparsity varies, but when zeroes make up more than 50 percent of any type of array, it can stand to benefit from sparsity-specific computational methods. In contrast, an object that is not sparse—that is, it has few zeros compared with the total number of elements—is called dense.

Sparsity can be naturally present, or it can be induced. For example, a social-network graph will be naturally sparse. Imagine a graph where each node (point) represents a person, and each edge (a line segment connecting the points) represents a friendship. Since most people are not friends with one another, a matrix representing all possible edges will be mostly zeros. Other popular applications of AI, such as other forms of graph learning and recommendation models, contain naturally occurring sparsity as well.

Beyond naturally occurring sparsity, sparsity can also be induced within an AI model in several ways. Two years ago, a team at Cerebras showed that one can set up to 70 to 80 percent of parameters in an LLM to zero without losing any accuracy. Cerebras demonstrated these results specifically on Meta’s open-source Llama 7B model, but the ideas extend to other LLM models like ChatGPT and Claude.

The case for sparsity

Sparse computation’s efficiency stems from two fundamental properties: the ability to compress away zeros and the convenient mathematical properties of zeros. Both the algorithms used in sparse computation and the hardware dedicated to them leverage these two basic ideas.

First, sparse data can be compressed, making it more memory efficient to store “sparsely”—that is, in something called a sparse data type. Compression also makes it more energy efficient to move data when dealing with large amounts of it. This is best understood by an example. Take a four-by-four matrix with three nonzero elements. Traditionally, this matrix would be stored in memory as is, taking up 16 spaces. This matrix can also be compressed into a sparse data type, getting rid of the zeros and saving only the nonzero elements. In our example, this results in 13 memory spaces as opposed to 16 for the dense, uncompressed version. These savings in memory increase with increased sparsity and matrix size.

In addition to the actual data values, compressed data also requires metadata. The row and column locations of the nonzero elements also must be stored. This is usually thought of as a “fibertree”: The row labels containing nonzero elements are listed and linked to the column labels of the nonzero elements, which are then linked to the values stored in those elements.

In memory, things get a bit more complicated still: The row and column labels for each nonzero value must be stored as well as the “segments” that indicate how many such labels to expect, so the metadata and data can be clearly delineated from one another.

In a dense, noncompressed matrix data type, values can be accessed either one at a time or in parallel, and their locations can be calculated directly with a simple equation. However, accessing values in sparse, compressed data requires looking up the coordinates of the row index and using that information to “indirectly” look up the coordinates of the column index before finally reaching the value. Depending on the actual locations of the sparse data values, these indirect lookups can be extremely random, making the computation data-dependent and requiring the allocation of memory lookups on the fly.

Second, two mathematical properties of zero let software and hardware skip a lot of computation. Multiplying any number by zero will result in a zero, so there’s no need to actually do the multiplication. Adding zero to any number will always return that number, so there’s no need to do the addition either.

In matrix-vector multiplication, one of the most common operations in AI workloads, all computations except those involving two nonzero elements can simply be skipped. Take, for example, the four-by-four matrix from the previous example and a vector of four numbers. In dense computation, each element of the vector must be multiplied by the corresponding element in each row and then added together to compute the final vector. In this case, that would take 16 multiplication operations and 16 additions (or four accumulations).

In sparse computation, only the nonzero elements of the vector need be considered. For each nonzero vector element, indirect lookup can be used to find any corresponding nonzero matrix element, and only those need to be multiplied and added. In the example shown here, only two multiplication steps will be performed, instead of 16.

The trouble with GPUs and CPUs

Unfortunately, modern hardware is not well suited to accelerating sparse computation. For example, say we want to perform a matrix-vector multiplication. In the simplest case, in a single CPU core, each element in the vector would be multiplied sequentially and then written to memory. This is slow, because we can do only one multiplication at a time. So instead people use CPUs with vector support or GPUs. With this hardware, all elements would be multiplied in parallel, greatly speeding up the application. Now, imagine that both the matrix and vector contain extremely sparse data. The vectorized CPU and GPU would spend most of their efforts multiplying by zero, performing completely ineffectual computations.

Newer generations of GPUs are capable of taking some advantage of sparsity in their hardware, but only a particular kind, called structured sparsity. Structured sparsity assumes that two out of every four adjacent parameters are zero. However, some models benefit more from unstructured sparsity—the ability for any parameter (weight or activation) to be zero and compressed away, regardless of where it is and what it is adjacent to. GPUs can run unstructured sparse computation in software, for example, through the use of the cuSparse GPU library. However, the support for sparse computations is often limited, and the GPU hardware gets underutilized, wasting energy-intensive computations on overhead.

Petra Péterffy

When doing sparse computations in software, modern CPUs may be a better alternative to GPU computation, because they are designed to be more flexible. Yet, sparse computations on the CPU are often bottlenecked by the indirect lookups used to find nonzero data. CPUs are designed to “prefetch” data based on what they expect they’ll need from memory, but for randomly sparse data, that process often fails to pull in the right stuff from memory. When that happens, the CPU must waste cycles calling for the right data.

Apple was the first to speed up these indirect lookups by supporting a method called an array-of-pointers access pattern in the prefetcher of their A14 and M1 chips. Although innovations in prefetching make Apple CPUs more competitive for sparse computation, CPU architectures still have fundamental overheads that a dedicated sparse computing architecture would not, because they need to handle general-purpose computation.

Other companies have been developing hardware that accelerates sparse machine learning as well. These include Cerebras’s Wafer Scale Engine and Meta’s Training and Inference Accelerator (MTIA). The Wafer Scale Engine, and its corresponding sparse programming framework, have shown incredibly sparse results of up to 70 percent sparsity on LLMs. However, the company’s hardware and software solutions support only weight sparsity, not activation sparsity, which is important for many applications. The second version of the MTIA claims a sevenfold sparse compute performance boost over the MTIA v1. However, the only publicly available information regarding sparsity support in the MTIA v2 is for matrix multiplication, not for vectors or tensors.

Although matrix multiplications take up the majority of computation time in most modern ML models, it’s important to have sparsity support for other parts of the process. To avoid switching back and forth between sparse and dense data types, all of the operations should be sparse.

Onyx

Instead of these halfway solutions, our team at Stanford has developed a hardware accelerator, Onyx, that can take advantage of sparsity from the ground up, whether it’s structured or unstructured. Onyx is the first programmable accelerator to support both sparse and dense computation; it’s capable of accelerating key operations in both domains.

CPUs, CGRAs, and FPGAs represent a trade-off between efficiency and flexibility. Each individual logic unit of a CPU is designed for a specific function that it performs efficiently. On the other hand, since each individual bit of an FPGA is configurable, these arrays are extremely flexible, but very inefficient. The goal of CGRAs is to achieve the flexibility of FPGAs with the efficiency of CPUs.

CGRAs are composed of efficient and configurable units, typically memory and compute, that are specialized for a particular application domain. This is the key benefit of this type of array: Programmers can reconfigure the internals of a CGRA at a high level, making it more efficient than an FPGA but more flexible than a CPU.

The Onyx chip, built on a coarse-grained reconfigurable array (CGRA), is the first (to our knowledge) to support both sparse and dense computations. Olivia Hsu

Onyx is composed of flexible, programmable processing element (PE) tiles and memory (MEM) tiles. The memory tiles store compressed matrices and other data formats. The processing element tiles operate on compressed matrices, eliminating all unnecessary and ineffectual computation.

The Onyx compiler handles conversion from software instructions to CGRA configuration. First, the input expression—for instance, a sparse vector multiplication—is translated into a graph of abstract memory and compute nodes. In this example, there are memories for the input vectors and output vectors, a compute node for finding the intersection between nonzero elements, and a compute node for the multiplication. The compiler figures out how to map the abstract memory and compute nodes onto MEMs and PEs on the CGRA, and then how to route them together so that they can transfer data between them. Finally, the compiler produces the instruction set needed to configure the CGRA for the desired purpose.

Since Onyx is programmable, engineers can map many different operations, such as vector-vector element multiplication, or the key tasks in AI, like matrix-vector or matrix-matrix multiplication, onto the accelerator.

We evaluated the efficiency gains of our hardware by looking at the product of energy used and the time it took to compute, called the energy-delay product (EDP). This metric captures the trade-off of speed and energy. Minimizing just energy would lead to very slow devices, and minimizing speed would lead to high-area, high-power devices.

Onyx achieves up to 565 times as much energy-delay product over CPUs (we used a 12-core Intel Xeon CPU) that utilize dedicated sparse libraries. Onyx can also be configured to accelerate regular, dense applications, similar to the way a GPU or TPU would. If the computation is sparse, Onyx is configured to use sparse primitives, and if the computation is dense, Onyx is reconfigured to take advantage of parallelism, similar to how GPUs function. This architecture is a step toward a single system that can accelerate both sparse and dense computations on the same silicon.

Just as important, Onyx enables new algorithmic thinking. Sparse acceleration hardware will not only make AI more performance- and energy efficient but also enable researchers and engineers to explore new algorithms that have the potential to dramatically improve AI.

The future with sparsity

Our team is already working on next-generation chips built off of Onyx. Beyond matrix multiplication operations, machine learning models perform other types of math, like nonlinear layers, normalization, the softmax function, and more. We are adding support for the full range of computations on our next-gen accelerator and within the compiler. Since sparse machine learning models may have both sparse and dense layers, we are also working on integrating the dense and sparse accelerator architecture more efficiently on the chip, allowing for fast transformation between the different data types. We’re also looking at ways to manage memory constraints by breaking up the sparse data more effectively so we can run computations on several sparse accelerator chips.

We are also working on systems that can predict the performance of accelerators such as ours, which will help in designing better hardware for sparse AI. Longer term, we’re interested in seeing whether high degrees of sparsity throughout AI computation will catch on with more model types, and whether sparse accelerators become adopted at a larger scale.

Building the hardware to unstructured sparsity and optimally take advantage of zeros is just the beginning. With this hardware in hand, AI researchers and engineers will have the opportunity to explore new models and algorithms that leverage sparsity in novel and creative ways. We see this as a crucial research area for managing the ever-increasing runtime, costs, and environmental impact of AI.
