Nano Banana Pro could already generate images so realistic, it’s almost impossible to tell that they were AI-generated. Google even had to limit its use due to high demand.

The new model will replace Nano Banana Pro in the Gemini app, but Google AI Pro and Ultra subscribers will retain access to Nano Banana Pro for specialized tasks. It will also be the default model in Search for AI Mode and Lens, as well as in Google’s Flow AI creative studio.
