- Released `gemini-3.5-flash`, the generally available (GA) version of
[Gemini 3.5 Flash](https://ai.google.dev/gemini-api/docs/models/gemini-3.5-flash),
our most intelligent model for sustained frontier performance on
agentic and coding tasks.

- Launched the **Managed Agents in the Gemini API** in public preview. This enables
developers to build and deploy autonomous, stateful agents that run in
secure, isolated Google-hosted Linux sandbox environments. To learn more,
see the [Agents overview](https://ai.google.dev/gemini-api/docs/agents) page and the
[Quickstart](https://ai.google.dev/gemini-api/docs/managed-agents-quickstart).

- Released the general-purpose **Antigravity Agent** managed agent,
[`antigravity-preview-05-2026`](https://ai.google.dev/gemini-api/docs/models/antigravity-preview-05-2026), in public preview.
The Antigravity agent can autonomously plan, reason, write and execute code,
manage files, and browse the web inside its sandbox container. See the
[Antigravity Agent](https://ai.google.dev/gemini-api/docs/antigravity-agent) guide for code
samples and specifications.
