Describe an idea or upload up to 14 reference images and explain what to keep and change. Nano Banana 2 is Google's fast image model; switch to Nano Banana Pro in the model menu when you want its higher-fidelity option.
Start from a written idea or from your own images. Name the subject, the composition and what must stay the same, then refine the prompt after reviewing the result.
Describe a subject, setting, lighting and style to get a first version you can review and refine.
Upload products, characters or style samples and explain each image's role, such as “use the product from image 1 with the lighting from image 2”.
Reuse the same reference images across generations and state what must not change, such as a face, an outfit or a color palette.
Ask for headlines, labels or signs and put the exact wording in quotes. Check the spelling in the result before you use it.
Pick from 10 aspect ratios and 1K, 2K or 4K output. The generator's size chart lists the pixels for each combination.
Nano Banana 2 uses 4 credits at 1K, 5 at 2K and 6 at 4K, for both text-to-image and image-to-image. Failed generations are not charged.
Describe where the image will be used and how it should be laid out, not only the visual style.
