Agent Substrate on GKE is now available for evaluation and non-production use.

Agent Substrate on GKE is now available for evaluation and non-production use. Production support is offered on an allowlist basis under a limited GA program.

Agent Substrate runs agentic workloads at scale on GKE clusters. To reduce resource usage, Agent Substrate suspends idle agents and takes a snapshot of the agent's active memory (RAM) and local files. When a suspended agent is triggered, the system restores the agent's state onto an available sandbox with sub-second latency.

Agent Substrate improves on the capabilities of Agent Sandbox by bypassing the bottlenecks of the standard Kubernetes control plane to run significantly more concurrent agents per machine.
