Google's Agent Substrate sandboxes AI agents on Kubernetes; Gemini API adds self-hosted sandboxes
Overview
Google adds support for self-hosted sandbox environments to Gemini API Managed Agents, letting developers bring their own sandbox, according to a Google AI Studio post on X. The post links to Google AI Studio for getting started and gives no further details on how the feature works.
The change follows Google's open-source Agent Substrate, a Kubernetes-based project that isolates AI agents in hardened sandboxes. Engineers Brandon Royal and Benjamin Elder explain the design, which injects credentials from outside the sandbox and snapshots idle agents out of memory and CPU to free cluster resources, according to Elder. Google says its Gemini Managed Agents already runs on Agent Substrate.
