Nano Banana 2 is an image generation and editing model built on the Gemini image stack and often associated with Gemini 3.1 Flash Image. It is intended for creating images from prompts and making precise edits that preserve important elements of the original visual, combining creative generation with practical revision workflows.

The model emphasizes realistic detail, clearer text rendering, and improved world knowledge while aiming to bring Pro-level generation and editing performance to the Flash tier. Its reported strengths suit posters, packaging, UI mockups, educational visuals, localized marketing, travel applications, storyboards, and product mockups, particularly where speed and scalable image editing matter alongside image quality.
