* Released `gemini-3.5-flash`, the generally available (GA) version of [Gemini
3.5 Flash](/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](/docs/agents) page and the
[Quickstart](/docs/managed-agents-quickstart).

* Released the general-purpose **Antigravity Agent** managed agent,
[`antigravity-preview-05-2026`](/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](/docs/antigravity-agent) guide for
code samples and specifications.
