Two newer Google image models are available in Snap AI Studio: Nano Banana 2 and Nano Banana Pro. They sit next to the original Nano Banana, which stays the default in most photo tools, and they run on the same credit balance as every other model in the app.

What each one is for

Nano Banana 2 is Gemini 3.1 Flash Image. It gives sharper detail than the original and accepts up to 6 reference images instead of 3. That makes it the middle ground on price for product and portrait edits, and for composites built from several photos.

Nano Banana Pro is Gemini 3 Pro Image. It is the one to pick for readable text in an image, complex multi-image composites, thumbnails and posters. It also takes up to 6 reference images. It costs more per image, so use it for final renders.

Where they run in the app

  • YouTube Thumbnail Generator defaults to Nano Banana Pro, the stronger of the two on readable text. The sample above was made with Nano Banana 2 in that tool.
  • Photo tools such as AI Photoshoot, AI Headshot Generator, AI Baby Generator, AI Age Predictor, Photo Restorer, LinkedIn Headshot and Pet Portraits list both models in the menu, with the original Nano Banana as the default.
  • Nano Banana Pro only: AI Product Photos, AI Poster Generator, AI Logo Generator and Object Remover list Pro but not Nano Banana 2.
  • AI Image Generator, AI Art Generator and the studio list every image model, including both.

Settings

Both models make one image per run in 1:1, 4:3, 3:4, 16:9 or 9:16. In photo tools the reference photos you upload go to the model with the tool's prompt; in the studio you can write your own prompt and add up to 6 images.

Tips that hold for both:

  • Spell out text in quotes. For a poster or thumbnail, write the exact words in quotes in the prompt. Nano Banana Pro is the stronger of the two here.
  • Use more references for composites. When you combine a person, a product and a background, upload all three as references.
  • Draft cheap, finish sharp. Find the look on the original Nano Banana, then rerun the same settings on Nano Banana 2 or Pro.

Known limits

Any failed generation is refunded automatically. Requests that the model's safety filter rejects are refunded up to a daily limit, as the content policy explains. Tools cap uploads at their own limit, so a tool that takes 4 photos still takes 4 even though these models accept 6.
