Nano Banana pricing
What one image costs on Root, in dollars; 100 credits is $1. You only pay for images that finish.

|---|---|---|
| Nano Banana Pro | $0.16 | $0.16 |
| Nano Banana | $0.05 | — |
A dash means that model has no 2K size. The API and the app both show the price before you run it. Use your own Google key in Root and those images cost nothing here. Compare every model
Nano Banana Pro or Nano Banana
| Model | Best for | Sizes |

| Nano Banana Pro | Finished images, and edits where the details have to hold. | 1K, 2K |
| Nano Banana | Quick drafts and edits at the lowest price. | Standard |
Both make new images from a prompt and edit images you give them. An image you make here can be the first frame of a video shot, or a reference for the next image, without leaving the project.
The Nano Banana Pro API
Make an API key in Root under Settings, then API. You choose a daily spending limit for each key when you create it. Then send a request:
curl https://root.film/api/v1/generations \
-H "Authorization: Bearer rfk_your_key" \
-H "Content-Type: application/json" \
-d '{"model":"gemini-3-pro-image","project_id":"YOUR_PROJECT_ID",
"input":{"prompt":"a hand-painted film poster for a noir set in Tokyo"}}'- For Nano Banana, send
gemini-2.5-flash-image. - The image is saved to the project you name, so your team sees it in the app too.
- Send an Idempotency-Key header and a retry never charges twice.
