What is Nano Banana Pro?
Nano Banana Pro is Google's premium model for generating and editing images. Its official name is Gemini 3 Pro Image and its model ID is gemini-3-pro-image. Google released it as a preview on November 20, 2025 and made it generally available on May 28, 2026.
Google describes it as a reasoning-driven model for professional work: complex graphic design, high-fidelity product mockups and data visualizations that need accurate text. It reasons through a prompt before it renders, outputs up to 4K through Google's API and accepts up to 14 reference images in one request.
On Nano AI you use Nano Banana Pro in the browser with no API key and no setup. Every image costs 32 credits, shown on the button before you generate. The 16 free credits of a new account do not cover a Pro image; they cover 2 images on Nano Banana 2.1, which sits in the same model menu.

Nano Banana Pro examples
These two images are Nano Banana Pro examples from Google's Gemini API documentation (CC BY 4.0), resized to 1200 pixels. They were not generated on Nano AI. The start of the prompt Google published is under each image.
What Nano Banana Pro is good at
Complex, layered prompts
Google positions Pro as its premium choice for the most demanding visual work, where one prompt carries many objects, a set layout and exact instructions.
Text that reads as written
Google names accurate text rendering as a reason to pick Pro: infographics, menus, diagrams and marketing layouts where a headline or a label has to be spelled correctly.
Three kinds of reference image
Through Google's API, Pro accepts up to 14 references: 6 objects, 5 characters and 3 style references. Nano AI currently accepts 5 reference images per edit.
It reasons before it renders
Pro is a thinking model. It works through the composition first and then renders the final image, which helps with prompts that have several constraints at once.
Grounded in Google Search
Through Google's API the model can look up current facts, such as a weather forecast, before it draws them. That control is not exposed on Nano AI yet.
A final pass, not a first draft
At 32 credits, Pro costs four times as much as Nano Banana 2.1 here. A common way to work is to draft on 2.1 at 8 credits and rerun the prompt that works on Pro.

FAQ
Nano Banana Pro FAQ
Short answers on price, free use and the names people search for.
Is Nano Banana Pro free to use?
Not with the sign-up credits alone. A new Nano AI account gets 16 free credits with no card required, and a Nano Banana Pro image costs 32. Those 16 credits cover 2 images on Nano Banana 2.1 or the original Nano Banana in the same model menu. If you sign up with a friend's invite link you both get 16 more, and 32 credits is exactly one Pro image.
What is the Nano Banana Pro price on Nano AI?
32 credits per image, the same for text-to-image and for edits. The smallest credit pack is the Starter Pack: $19.9 for 1,600 credits, which is 50 Nano Banana Pro images, and pack credits never expire. For comparison, Nano Banana 2.1 and the original Nano Banana cost 8 credits per image and Nano Banana 2 costs 12.
Is there a Nano Banana 2 Pro?
Google has not released a model with that name. Its documentation, read on October 13, 2026, lists Nano Banana Pro, Nano Banana 2.1, Nano Banana 2, Nano Banana 2 Lite and the original Nano Banana. A search for Nano Banana 2 Pro usually means Nano Banana Pro, the premium model on this page, or Nano Banana 2. Both are in the model menu here.
What is the difference between Nano Banana AI and Nano Banana Pro?
Nano Banana AI is how people refer to Google's Nano Banana family of AI image models as a whole. Nano Banana Pro is the premium model in that family, built on Gemini 3 Pro. Nano AI offers four models of the family: Nano Banana, Nano Banana 2, Nano Banana 2.1 and Nano Banana Pro.
Nano Banana Pro or Nano Banana 2.1: which should I use?
Start with Nano Banana 2.1 at 8 credits and move to Pro at 32 when a result has to be exactly right. Google still presents Pro as its premium model for the most complex work, and Pro accepts style references. In the human side-by-side tests Google published with the Nano Banana 2.1 model card, 2.1 scored 1050 for overall preference and Pro scored 935, so compare both on your own prompt.
Does Nano Banana Pro support 4K?
The model outputs 1K, 2K and 4K through Google's API. Nano AI currently generates at 1K, which is 1024 × 1024 pixels for a square image. Larger sizes are not enabled here yet.
How many reference images can I use?
Through Google's API, Nano Banana Pro accepts up to 14: 6 objects, 5 characters and 3 style references. Nano AI currently accepts up to 5 per edit, each up to 5 MB.
How much does the Nano Banana Pro API cost?
Google's paid tier charges $2.00 per million input tokens and $120 per million image output tokens. That works out to $0.134 for a 1K or 2K image and $0.24 for a 4K image, and there is no free API tier. On Nano AI you need no API key, and an image costs 32 credits.
When was Nano Banana Pro released?
