Google says the service already powers Gemini for business work tasks and will enter preview in the coming months.
The service uses rapid-boot microVMs, copy-on-write memory sharing, checkpoint-and-restore for idle sessions, Hyperdisk persistence, and short-lived per-agent credentials. Google says credentials are injected outside the microVM, while Agent Gateway provides observability, policy, and security evaluation. The runtime uses Titanium IPUs and a Cloud Hypervisor boundary.
Google also open-sourced Agent Substrate for GKE, a Kubernetes-native runtime supporting microVM or gVisor isolation. Google reports up to 10x compute density versus traditional compute and, in a 200,000-agent benchmark, 500 activations per second with under-500 ms suspend-and-resume latency. The announcement does not provide preview dates, pricing, regional availability, independent benchmark validation, or general-availability terms.
