gemini-3-pro-image (Nano Banana Pro) on Vivgrid: Google's highest-quality image generation and editing model, with per-image token pricing.

`gemini-3-pro-image`, also known as **Nano Banana Pro**, is Google's highest-quality image generation and editing model. It applies Gemini 3 reasoning to image work, which makes it the strongest option for complex, multi-turn generation and editing, accurate text rendering inside images, and high-fidelity design output.

On Vivgrid, `gemini-3-pro-image` runs as a globally centralized model reachable through the same OpenAI-compatible endpoint and unified key as every other model in the catalog.

## Image token conversion

Images are billed as tokens, so the per-image cost follows the resolution you ask for:

| Item              | Tokens | Cost per image |
| ----------------- | ------ | -------------- |
| Input image       | 560    | \$0.0011       |
| Output image (1K) | 1,120  | \$0.134        |
| Output image (2K) | 1,120  | \$0.134        |
| Output image (4K) | 2,000  | \$0.240        |

Text and thinking tokens are billed at the text output rate of \$12.00 per 1M tokens.

## Ideal use cases

- Complex graphic design and marketing assets
- High-fidelity product mockups
- Infographics and data visualizations that require accurate text rendering
- Multi-turn, conversational image editing
