## Use it in Studio

1. **Open Create Image** In Studio, open **Create Image**. Sign in when the Studio asks, because every generation needs an account.
2. **Choose Nano Banana 2** Open the model picker, which groups models by maker, and choose Nano Banana 2.
3. **Write your prompt** Describe the image. To start from a picture, attach one reference image (JPEG, PNG or WEBP, up to 20 MB).
4. **Set the output** Choose an aspect ratio, a resolution and **Count** from 1 to 4.
5. **Check the price and generate** The Studio shows the credit price for your settings. It is the same price the server charges. Results appear as cards and are saved to your **Library**.

## Limits

- You need to be signed in to generate. Nano Banana 2 is available on every plan, including Free; credits are the limit.
- One reference image only, and a run with a reference image makes 1 image, not 1 to 4.
- If a generation fails, the credits are refunded. The Studio does not run a different model in its place.
