Nvidia debuts OpenShell Reference Architecture for agent governance

Nvidia announced the OpenShell Reference Architecture on October 21, 2026, at GTC Berlin, a full-stack design for building, containing and enforcing safe AI agents across enterprise and edge systems. It combines Vera Rubin NVL72 systems, Vera CPUs and BlueField-4 DPUs running the Sentry security framework.

• Vera Rubin NVL72 delivers 30x higher throughput per megawatt for agentic workloads
• Vera with 88 Olympus cores is claimed 2x faster than x86 CPUs
• BlueField-4 with Sentry quarantines a policy-breaking agent in milliseconds
• CoreWeave: sandbox startup 3x faster on Vera, one rack hosts 11,000 agent environments
