About Nano Banana Pro

Nano Banana Pro is Google's Gemini 3 Pro Image model. It uses Gemini's reasoning to plan an image before drawing it, which helps with complex scenes, infographics, diagrams and text inside the image.

In Kinoseed it generates from a prompt or edits a reference image you upload. It costs more per image than Nano Banana 2, so a common workflow is to draft with Nano Banana 2 and switch to Pro for the final version.
