Powering Open Infrastructure for Autonomous Agents
Google, Thursday, November 5th, 2026
Google donated Agent Substrate, gVisor and OpenRL to the CNCF and made Agent Substrate 1.0 generally available on GKE.
Google is donating three open source projects, Agent Substrate, gVisor and OpenRL, to the Cloud Native Computing Foundation after their acceptance into the CNCF Sandbox, with gVisor on a path toward Incubation.
Agent Substrate has reached 1.0 and is generally available on GKE.
It decouples stateful agent sessions from active compute, snapshotting idle agents and restoring them in under 500 milliseconds to run millions of sandboxes at 10x container density.
gVisor isolates untrusted, agent-generated code in a userspace application kernel, and OpenRL orchestrates reinforcement learning post-training across parallel sandboxed rollouts, all runnable on any Kubernetes cluster across CPUs, GPUs or TPUs.
