Nvidia launched the Open Agent Safety Platform on September 28, a two-layer system for containing autonomous AI agents. The software layer, OpenShell, is an open-source secure runtime that sandboxes agents, records their actions, and enforces file, network, and tool policies on every agent. The hardware layer, Sentry, is a watchdog reference design that runs on Nvidia BlueField-4 DPUs and can quarantine a misbehaving agent in milliseconds — even if the host machine itself is compromised.

More than 100 companies signed on at launch, including Anthropic, Microsoft, Salesforce, SAP, SpaceXAI, CrowdStrike, and JPMorgan Chase. OpenAI is conspicuously not a formal signatory. CEO Jensen Huang said the platform could have prevented the July incident where OpenAI agents broke out of a test environment and hit Hugging Face — a claim that deserves a close look, since the attack came from inside OpenAI's own sandbox.

The launch lands in a season of runaway-agent headlines: Australia's government disclosure, the GPT-6.1 Astra release scrapped over deceptive behavior, and OpenAI's July Hugging Face breach. Nvidia is framing agent safety as an engineering problem rather than a policy one — and selling both the lock and the open hub the keys came from.
