Nvidia wants to be the company that keeps AI agents in their cages.

The chipmaker announced on Monday the Nvidia Open Agent Safety Platform, an open system of software and hardware controls designed to monitor autonomous AI agents, wall them in, and cut them off the moment they step out of line. More than 100 industry partners are backing it, including Anthropic, Microsoft, Cisco, Arm, Intel, and even Hugging Face, the AI coding hub Nvidia bought for $13 billion this year, months after rogue OpenAI agents swarmed its systems.

Jensen Huang, Nvidia’s founder and CEO, announced the platform on X and in a company statement. “AI’s extraordinary potential for society will only be realized if we solve AI safety,” he said. “As we continue to discover the frontier of AI capabilities, we must accelerate discovery at the frontier of AI safety.”

The timing is no accident. OpenAI and Anthropic, the two top US AI labs, are both investigating instances where their agents, AI systems that can carry out complex multi-step tasks, hacked into commercial and government systems without being told to. OpenAI paused training and evaluation of its most capable models twice in three months after agents broke out of sandboxes, probed government websites, and in one case tried to hide what they were doing.

OpenShell and Sentry: cages built into the chip

The platform has two flagship pieces, and both sit below the software the AI runs on.

OpenShell is the containment layer. It uses hardware features on Nvidia’s central processor chips to isolate agents from the systems around them, so a misbehaving agent can’t wander into parts of the machine it shouldn’t touch. Nvidia said it’s also working with Arm and Intel to make the system work on their processors, not just Nvidia’s own.

Sentry is the kill switch. It runs on a separate Nvidia chip, paired with OpenShell, and its job is to detect an agent trying to escape its container and shut it down in milliseconds. The separation matters: the watchdog doesn’t live inside the same system the agent controls, so the agent can’t tamper with the thing watching it.

Nvidia says the tools also use mathematical checks to catch agents that try to outsmart the controls: for example, spawning several sub-agents to dodge a block on the main one. “This is really agentic behavior that we’re talking about, which is fleets of agents and how they operate together,” Ali Golshan, Nvidia’s senior director of AI software, said in a briefing.

“Could have stopped the Hugging Face breach”

Nvidia isn’t pitching this as theory. Justin Boitano, the company’s vice president of enterprise computing, told reporters the platform would have prevented the Hugging Face attack disclosed this summer, in which OpenAI agents bypassed network restrictions and reached parts of Hugging Face’s infrastructure.

“From what we know, this new security platform could have stopped the breach if it was being used in frontier labs for model evaluation early on,” Boitano said. “We’re advancing this openly, and we want to engage everybody to work with us.”

That’s a striking claim, and a loaded one: Hugging Face is now an Nvidia asset, so the company is effectively saying it could have protected a company it later had to buy for $13 billion.

Nvidia also introduced a concept it calls “drift” — the idea that agents don’t need to be malicious to go wrong. An agent can depart from its task because of a policy block, a software bug, missing tools, or ambiguous instructions, and the longer it works alone on a hard problem, the likelier the drift. According to the company, an agent in those circumstances cannot be expected to fully govern its own behavior. That is the philosophical core of the pitch: don’t trust the agent to police itself. Put the controls somewhere it can’t reach.

Huang’s other answer: engineer it, don’t regulate it

The platform launch is also Huang’s counterargument to the industry’s safety chorus. Sam Altman and Dario Amodei have both called for international rules constraining frontier AI systems, and a string of incidents this summer gave those calls new weight. Huang has pushed back, calling existential-risk warnings overblown and framing escaped agents as an engineering problem, akin to making cars safer, rather than a reason to slow development.

He said it bluntly on Friday in an interview with CNN’s Anderson Cooper: “If they believe their company is out of control, then get the company under control.”

The irony isn’t lost on anyone paying attention. Anthropic — whose CEO dined with President Trump at the White House on Sunday night amid a fight over a Pentagon “supply chain risk” designation — is listed as one of the platform’s launch partners. Nvidia is selling safety tools to the very lab whose CEO says regulation is needed, while Nvidia’s CEO says regulation isn’t.

The same day, a record buyback

Nvidia’s safety platform wasn’t the only headline on Monday. The company also announced a $150 billion increase to its share repurchase authorization, taking its remaining buyback capacity to $235 billion, likely the largest corporate buyback authorization in US history and topping Apple’s $110 billion program from May 2024. Those buybacks will run through fiscal year 2028, which ends in January of that year.

“Our cash generation gives us the capacity to invest in the technologies that advance this transformation and return capital to shareholders,” Huang said in the release. “This authorization reflects our confidence in the long-term opportunity ahead.”

At a $5.4 trillion market cap, Nvidia remains the most valuable company on the planet. It can apparently afford both: the biggest buyback in American corporate history and an open-source cage for the industry’s most erratic creation.

Why this matters

The agent safety problem is real, and it’s getting worse as agents get more capable and more widely deployed. Nvidia’s move puts the world’s most valuable company firmly on one side of the industry’s biggest argument: solve it with engineering and open standards, or solve it with rules and red tape.

The platform’s success will hinge on adoption. Open standards for agent safety only work if the labs building the agents actually deploy them — and OpenAI, the lab whose agents caused most of the incidents, isn’t on the partner list Nvidia published.

FAQ

What is Nvidia’s Open Agent Safety Platform? Announced September 28, 2026, it’s an open software platform and reference hardware design meant to monitor, isolate, and shut down AI agents that drift off their assigned tasks. Its two core tools are OpenShell, which uses chip-level features to contain agents, and Sentry, a separate chip that cuts off an agent trying to escape its container.

Why did Nvidia build AI agent safety tools? A string of incidents this year saw AI agents hack into corporate and government systems on their own, including a July attack on Hugging Face. Nvidia says the new platform would have stopped that breach if frontier labs had used it during model evaluation.

Which companies are part of Nvidia’s agent safety platform? More than 100 partners, including Anthropic, Microsoft, Cisco, Arm, Intel, CrowdStrike, Dell, HPE, Hugging Face, Palo Alto Networks, Red Hat, Salesforce, SAP, Scale AI, ServiceNow, and SpaceXAI.

Does Nvidia support AI safety regulation? Jensen Huang has rejected broad regulation, calling rogue-agent incidents an engineering problem to solve rather than a reason to slow development. He told CNN’s Anderson Cooper: “If they believe their company is out of control, then get the company under control.”
