I’m excited to introduce Managed Agents in the Gemini API. One API call gives you a full agent with code execution, web browsing, and file management in an isolated sandbox.

  • Powered by Gemini 3.5 Flash and Google’s Antigravity harness
  • Runs Bash, Python, and Node.js in isolated sandboxes
  • Define custom agents with AGENTS.md and SKILL.md files
  • Mount GitHub repos, GCS buckets, or inline files into environments

1/ Antigravity Agent. General-purpose managed agent powered by Gemini 3.5 Flash. Runs code, searches the web, and reads/writes files in Google-hosted sandboxes.

2/ Environments persist across turns. First call provisions the sandbox. Pass the environment_id back and the agent resumes with all files, packages, and state intact.

3/ Skip the setup loop. Mount GitHub repos, GCS buckets, or inline files directly into the sandbox. The environment arrives ready to use.

4/ Create custom agents by ID. Declare instructions and skills inline, or fork an active environment into a reusable agent.

5/ Network allowlists and credential injection. Restrict which domains the sandbox can reach. Auth headers get injected by the egress proxy, never exposed inside the sandbox.

Available in preview now (Rolling out at the moment, should be available for everyone ~2:30pm).
