About gemini-2.5-flash-lite

gemini-2.5-flash-lite is a text-output member of the Gemini 2.5 family, documented for classification, simple extraction and lightweight text processing. It processes text, images, audio and video; its multimodal understanding produces text rather than generated media.

Google currently limits 2.5 access to users who previously used the models, while explicitly saying they are not deprecated. New projects are directed to newer versions. A platform listing does not establish eligibility on a given route.

Official reference, checked 2026-10-14.

Use cases and prompting

  1. Provide all labels and an unknown rule for classification and check rare categories.
  2. Use public material with known answers to validate multimodal formatting on the route.
  3. Confirm access to this existing version and retest thinking and tools when migrating.
  4. Compare the same test cases with gemini-3.5-flash-lite; check request and response formats in the API documentation.
