Also known as Gemini 3 Pro Image — sharper detail and cleaner in-image text, from 14 credits at 1K/2K.



Nano Banana Pro is the common name for Gemini 3 Pro Image, the higher-fidelity tier of Google's Gemini 3 image family. Gemini 3 Pro Image is the higher-fidelity tier of Google's Gemini 3 image family. Both tiers accept a prompt or reference images and return one image, but Pro spends more compute per frame on the parts of an image that break first: small lettering, product edges, skin and metal texture, and the way a subject holds its shape when you generate a second and third shot.
It keeps the same three ratios, 1:1, 3:4 and 4:3, and the same 1K, 2K and 4K sizes, so moving between tiers does not change your workflow. What changes is price: 14 credits at 1K and 2K, 24 at 4K, against 6, 10 and 12 on Gemini 3.1 Flash Image. The practical split is to iterate on Flash and finish on Pro. Current credit packs are listed on the pricing page.
The gap between the two Gemini tiers shows up in exactly the places clients notice. Short strings on packaging, a label on a bottle, a headline on a poster, stitching on a jacket and highlights on metal all hold together better on Pro, which means fewer rejected finals and less time spent fixing a frame by hand.
Reference consistency is the other reason. When you upload up to 9 images of the same product or character, Pro tracks the subject more reliably across ratios and sizes, so a set of shots for a listing or a carousel still reads as one item. It also pays off in the 4K pass: 24 credits is the most expensive single generation here, and it is worth spending only when the frame is already approved. For text that has to be cleaned up or translated afterwards, Remove Text From Image and AI Image Translator cover that step.
For cheap drafts before the final render, send the same prompt to Nano Banana 2 (Gemini 3.1 Flash Image); when the job is text-heavy layouts or OpenAI-style prompting, compare against GPT Image 2.
