Nano Banana Pro
For complex compositions, infographics, and precise in-image text at 2K/4K — final assets for advertising and print
About the model
Nano Banana Pro is built on the Gemini 3 Pro Image architecture from Google DeepMind and is designed for work that ships in the final product with no manual touch-ups. That means assets with high demands on resolution, precise typography, and consistency between frames.
The model handles complex multi-part requests confidently and keeps characters and objects consistent across multiple generations — a rare quality that makes it a fit for storyboards and serial campaigns. On top of that, the professional version renders in-image text accurately, which matters for packaging, posters, and UI graphics with captions.
Generation cost depends on the chosen resolution: 1K and 2K are cheaper, 4K is the most expensive. Use this model selectively for final frames, and reach for the base Nano Banana for drafts and quick iterations.
