Google donates Agent Substrate and gVisor to CNCF to sandbox AI agents that idle 90-95% of runtime
rseroter · x · 2026-11-06
Google announced donating Agent Substrate and gVisor to the Cloud Native Foundation (alongside OpenRL) for open agent ecosystem governance.
Key facts:
- AI agents spend 90%–95% of runtime idle waiting for models, yet need sub-second wakeups;
- Agent Substrate on GKE achieves sub-500ms agent wakeups with zero running-pod compute costs via stateful sandboxes;
- The stack includes gVisor isolation, dedicated pods vs stateful actor runtime, atenet routing, and tiered memory, demoed at KubeCon NA.
