Nano Banana Pro is a free web-based AI image generator that creates images from text descriptions and edits existing images using artificial intelligence. It is powered by Google Gemini models and hosted on Vercel.

The product offers text-to-image generation where users describe what they want and get an AI-generated image. It supports image editing capabilities allowing users to upload an image and describe changes they want. The platform provides multiple aspect ratios including 1:1 (square), 16:9 (landscape), 9:16 (portrait), 4:3, and 3:4. It features two generation modes: Pro (highest quality) and Classic (faster, ~2x speed). Generated images have no watermarks and the service is free to try without requiring an account.

Users enter a text prompt describing the image they want and optionally upload reference images. They select their preferred aspect ratio and generation mode, then click Run to generate the image. They can download, copy, or continue editing the result.

The service provides free AI image generation and editing capabilities accessible to anyone without sign-up requirements.

Nano Banana Pro uses Google Gemini image generation models accessed through Vercel AI Gateway. Pro mode uses Gemini 2.0 Flash for best quality while Classic mode uses Gemini 2.5 Flash for faster generation.
