# Nano Banana Pro

> Google's top model: best quality, complex scenes, posters and infographics.

Nano Banana Pro is Google's most capable image model for complex scenes, infographics, posters and photo-realistic pictures. You can add up to 8 of your photos.

| Mode | ID | Price |
|---|---|---|
| [Edit a photo](#edit-a-photo) | `nano-banana-pro` | 1K $0.030 · 2K $0.035 · 4K $0.040 |

## Compatibility

apimart/OpenAI-style requests work too:

- `model`: `nano-banana-pro`, `google/nano-banana-pro`, `nano-banana-pro-ext`, `gemini-3-pro-image-preview`, `gemini-3-pro-image-preview-official`.
- `size` instead of `aspect_ratio`: a ratio (`16:9`) or exact pixels (`1600x1200`) — we use the closest supported ratio.
- Photos can go in `image_urls`, `image_input` or `input_urls`. Parameters may also be sent at the top level of the body, without the `input` wrapper.
- `resolution` in any case (`1k`, `2K`); `jpg` and `jpeg` are the same. `n` must be `1` (one image per request).
- `nsfw_check`, `official_fallback`, `google_search` are accepted but do not change the result.
