About Nano Banana 2
What it does
Gemini 3.1 Flash Image takes a text prompt, one or more reference images, or both, and returns a still image. It supports both text-to-image and image-to-image, so you can generate from a description alone or feed it an existing photo to edit or restyle. Framing is selectable per pipeline: 1:1, 16:9, 9:16, 4:3 and 3:4 in Image Generator and Image Editor.
When to use it
- Image Generator. Make images from text or reference photos: product shots, character art, posters with readable text, photoreal portraits.
- Image Editor. Change style, remove objects, modify single elements, or transform the whole look of an image you upload.
- Any job where you want several reference images steering a single result, since this model accepts multi-image refs.
What to know before you run it
Two render tiers are billed here: a standard 1K image and a 2K image selected with the HD quality option. Reserve HD for work you will crop, print, or zoom into, and leave it off for drafts and variations. Image Editor starts from an image you supply, and Image Generator runs from text or from reference photos. Google retires this model on October 29, 2026, and Nano Banana 2.1 replaces it.
