About gemini-3-pro-image-preview

gemini-3-pro-image-preview is a historical Nano Banana Pro preview ID. Google's current lifecycle table lists its shutdown on 2026-06-25; this page identifies old configurations and supports migration rather than establishing current preview availability.

If a platform route still accepts the old string, confirm whether it is a compatibility name or maps to another version. Revalidate text, subject consistency and output formatting on the replacement instead of retaining preview-era assumptions.

Official reference, checked 2026-10-14.

Use cases and prompting

  1. Locate the preview string and retain original assets and outputs as migration cases.
  2. Check the route's served model and error details to establish old-name compatibility.
  3. Retest references, sizes and multi-turn edits on the replacement and inspect each final image.
  4. Compare the same test cases with nano-banana-pro; check request and response formats in the API documentation.
