Google Nano Banana 2.1
Google's updated Nano Banana 2 image model, with sharper graphic composition, steadier subjects across edits and closer prompt following, from text or up to 14 reference images at 1K to 4K.
Nano Banana 2.1 is a cloud image-generation model built by Google. It generates images from a text prompt, and can take reference images to guide style or composition (image-to-image). It outputs up to 4K across 14 aspect ratios. Images can be saved as PNG, JPEG, and WebP. It runs through Runware, Replicate, OpenRouter, and Google using your own API key, from about $0.0336 per image.
