Google open-sources Agent Substrate: millions of agent sandboxes at 10x density on GKE
rseroter · x · 2026-09-17
Google announced Agent Substrate on GKE: an open-source, secure-by-default agent execution runtime that runs millions of sandboxes at 10x higher density than standard container runtimes. It delivers sub-500ms resume operations at over 500 suspend/resume activations per second, with native zero-trust kernel and network isolation to mitigate risks from model-generated code. It runs on any Kubernetes infra and is optimized for GKE. Nous Research's Hermes Agent — #1 AI agent globally by OpenRouter usage — is already building on it.
