About gemini-3.1-flash-lite-image

gemini-3.1-flash-lite-image is Google's Nano Banana 2 Lite image-generation and editing model. It can return interleaved text and images and is positioned for lightweight interactive visual workflows such as color swaps, stickers and background changes.

This model supports 1K output rather than 2K or 4K, and search grounding is not supported. Check platform image controls, output structure and measured latency instead of borrowing another Nano Banana model's specifications.

Official reference, checked 2026-10-14.

Use cases and prompting

Start with a 1K target and specify one local change.
Identify subject edges and details that must survive a background adjustment.
Read the returned image data and inspect size; avoid unsupported 2K or 4K requests.
Compare the same test cases with gemini-nano-banana-2.1; check request and response formats in the API documentation.
