Nano Banana FAQs
Nano Banana is Google’s Gemini 2.5 Flash Image model for creating and editing images. On Image Fx, you can create images from text or upload up to 10 reference photos and describe the change in plain language, with every image priced at 3 credits.
You’ll need a paid plan or purchased credits to use Nano Banana on Image Fx. Sign in to generate images at 3 credits each. Free credits alone do not unlock this model. You can browse and copy the prompt examples on this page for free.
3 credits per image, the same for text-to-image and editing regardless of aspect ratio or how many references you add. Generate up to five images per run; the total shows on the button before you confirm.
Add a photo and describe the change the way you would to a person: change the sky to sunset, remove the person on the left, or turn this sketch into a photo. Keep each edit focused, then use the result as a reference and refine it in another pass.
Up to 10 JPG, PNG or WEBP images, up to 30 MB each. Add a photo and describe the edit, or combine several references and tell Nano Banana which details to keep from each one.
Nano Banana can carry the same person or product across new scenes, poses, and styles. Use the same reference image and say what should stay unchanged, such as a face, outfit, or product design. Compare each result with the original before using it.
Choose Auto or 10 fixed ratios, from square 1:1 to wide 21:9 and tall 9:16. Auto uses your reference image’s aspect ratio. Nano Banana has a single output size, so there is no resolution to choose.
Nano Banana is the original Gemini 2.5 Flash Image model: quick, affordable and good for everyday edits. Switch to Nano Banana 2 when you need 2K or 4K output, more reference images or sharper text in the image. Try the same prompt in both and compare the results.
Name the subject, setting, style and composition. For text in the image, put the exact words in quotes. With a reference photo, say what should stay the same and what should change. Refine in a second run instead of packing everything into one prompt.
Taking longer than expected? Choose Check again or open My images to check on your image at no extra credit cost. Credits are refunded automatically for images that fail. If you’re unsure whether generation started, check My images before trying again to avoid using credits twice.
