Nvidia Unveils OpenShell Reference Architecture for AI Agents
Nvidia unveiled the OpenShell Reference Architecture at GTC Berlin, a full-stack design that pairs its Vera CPUs, OpenShell software, and BlueField-4 chips to contain and monitor autonomous AI agents. The architecture treats every agent workload as untrusted and grants access only when needed, with four parts: a gateway, supervisor, sandbox, and policy prover. BlueField-4, a data processing unit, sits on the node's only path to the model, allowing Sentry to inspect traffic between an agent and the model without relying on the agent to report on itself.
