What is Nano Banana Pro?
Nano Banana Pro (also referred to as AI Image Editor on the platform) is a web-based tool that lets you generate images from scratch or edit existing photos using natural language instructions. It runs on the Gemini 3.1 Flash Image model from Google DeepMind, combining the speed of Gemini Flash with Pro-level visual quality. The tool supports PNG, JPG, and WebP uploads and outputs images up to 4K resolution with SynthID watermarks and C2PA Content Credentials for provenance.
