Try Nano Banana 2

Nano Banana 2 is the nickname for Google's Gemini 3.1 Flash Image model. It generates new images from a text prompt and edits existing photos from plain-language instructions, and it does both quickly.

It's AirGallery's default model: a good first choice for most prompts, edits and style changes. Upload one or more photos, describe what you want, and download the result.

Sample images
