- What happened
- Gemini API Managed Agents now default to Gemini 3.6 Flash, add environment hooks for tool call auditing, and include budget controls and free tier access.
- Why it matters
- Matters for engineers building autonomous agents who need cost control, security validation of agent actions, and access without paid accounts.
- Watch out
- Environment hooks run inside remote sandboxes with timeout limits; budget controls pause execution at token limits rather than failing, requiring resume logic.

Managed Agents in Gemini API now default to Gemini 3.6 Flash. New environment hooks let you block, lint, or audit tool calls inside the sandbox. Also, we’ve added budget controls, scheduled triggers, and free tier access.
