Nano Banana in Google AI Studio: Step-by-Step Guide
Google AI Studio is Google’s browser workspace for its Gemini models, including every Nano Banana image model. It is built for developers and power users: you test prompts, compare models and then take the same request into code through the Gemini API.
How to use Nano Banana in Google AI Studio
- Go to aistudio.google.com and sign in with a Google account.
- Start a new prompt and open the model picker.
- Choose an image model: Nano Banana 2 (
gemini-3.1-flash-image), Nano Banana 2 Lite (gemini-3.1-flash-lite-image), Nano Banana Pro (gemini-3-pro-image) or the newer Nano Banana 2.1 (gemini-nano-banana-2.1). - Type a prompt, or attach images and describe an edit.
- Run it, review the image and iterate. When it works, use Get code to copy the same request into your app.
Does Nano Banana cost money in AI Studio?
Google’s Gemini API pricing page lists image models as not available on the free tier, so image generation is billed per image on a project with billing enabled. Current list prices run from $0.0336 per image (Nano Banana 2 Lite and 2.1 at 1K) to $0.24 (Nano Banana Pro at 4K). The Nano Banana API guide has the full table and a code sample. For free use without a developer account, the Gemini app is the better route; see Is Nano Banana free?
