What stands out

What its maker marketed at launch, and what people found later, each with its source.

  • Autonomous multi-step web research as an API agent

    Runs iterative searching and reading for several minutes and returns a synthesized report; only via the Interactions API with background=true (poll or stream), not generate_content. ‘Max’ trades speed for comprehensiveness.

Notes

Agent ids, not raw models; the underlying Gemini model and pricing are not stated on the docs page (checked 2026-10-09). The older deep-research-pro-preview-12-2025 was deprecated on 2026-10-08 and shuts down on 2026-10-23 (Gemini API changelog); migrate to deep-research-preview-04-2026 or deep-research-max-preview-04-2026.

See the docs page for request examples (background execution is required).
