Nano Banana Pro is Google's product name for Gemini 3 Pro Image, positioned for more complex image production with a stronger focus on accuracy. It suits images that must communicate information clearly, such as brand key visuals, product promotions, infographics, posters with multiple lines of text, and localized assets. Creators can describe content, layout hierarchy, and visual tone in text, or add reference images to guide editing through existing subjects, colors, or brand direction. Beyond quickly producing a sketch, this version places greater emphasis on world knowledge, instruction understanding, text in images, and detail control, supporting repeated revisions while maintaining the creative objective. It offers 1K, 2K, and 4K output and a separate editing mode for developing ideas into more finished assets. In practice, make a checklist of headings, numbers, trademarks, and text that must be exact. Even readable generated text still needs final proofreading. For brand consistency, provide clear references and identify every element that must be preserved, rather than leaving key requirements for the model to infer.
Combines multiple pieces of information, layout requirements, and visual elements in a single image.
Suits posters, infographics, and product assets; key text still requires human proofreading.
Both text-to-image and editing offer 1K, 2K, and 4K output.
