How to use Nano Banana Pro in the Gemini app
- Open the Gemini app or gemini.google.com and sign in with an account on a Google AI plan.
- Start an image request: describe the picture, or upload a photo and describe the change.
- Choose Pro. Google has changed the label over time: at launch you picked the “Thinking” model with Create images; on current plans you can redo an image with Nano Banana Pro after it is made.
- Ask for follow-up changes in the same chat, then download the image.
Free accounts generate with Nano Banana 2 instead. The details are on Nano Banana Pro free.
How to use Nano Banana Pro in Google AI Studio

How to use Nano Banana Pro in Photoshop

How to use Nano Banana Pro on Nano Banana AI
- Sign in with Google or email.
- In the studio, choose Nano Banana Pro from the model list.
- Pick a resolution: 1K, 2K or 4K. On this site 1K and 2K cost the same, so 2K is the better default.
- Write your prompt, or attach up to 4 reference images for an edit or a composite.
- Generate, then refine with a follow-up edit.
Nano Banana Pro is included in the Pro plan (29.99/month for 10,000 credits). See pricing.
Settings that make Pro worth it
- Resolution. Draft at 1K or 2K and rerun the winner at 4K for print or full-screen use.
- Text. Put exact words in quotes and say where they go. Pro handles several lines; the Flash models struggle with long text.
- References. Refer to uploaded images by order: “the person from the first photo, the product from the second”.
- Patience. Pro plans the image before drawing it, so expect roughly twice the wait of Nano Banana 2.
