Currently, it’s rolling out in the Gemini app. When you use the “Create image” option, you’ll see a tooltip saying “Generating image with Nano Banana Pro.”

And in AI Studio, you need to connect a paid API key to use it:

> Nano Banana Pro is only available for paid-tier users. Link a paid API key to access higher rate limits, advanced features, and more.

Phased rollouts are fairly common in the industry.

Already available in the Gemini web app for me. I have the normal Pro subscription.

I don't see in the ai studio

I see it but when I use it says "Failed to count tokens, model not found: models/gemini-3-pro-image-preview. Please try again with a different model."
