# Pricing

> AI Image Generation pricing per engine and resolution

AI Image Generation pricing varies by engine and resolution. View current pricing at [bunny.net/pricing](https://bunny.net/pricing).

## Pricing per image

| Engine                            | Code         | Resolution | Price/Image |
| :-------------------------------- | :----------- | :--------- | :---------- |
| **DALL-E 2 (256px)**              | `dalle-256`  | 256x256    | **\$0.016** |
| **DALL-E 2 (512px)**              | `dalle-512`  | 512x512    | **\$0.018** |
| **DALL-E 2 (1024px)**             | `dalle-1024` | 1024x1024  | **\$0.020** |
| **Stable Diffusion v1.5 (512px)** | `sd15-512`   | 512x512    | **\$0.001** |
| **Stable Diffusion v2.1 (512px)** | `sd21-512`   | 512x512    | **\$0.001** |
| **Stable Diffusion v2.1 (768px)** | `sd21-768`   | 768x768    | **\$0.030** |

## Cost optimization

### Caching

Generated images are cached at the edge for up to 3 months. The same prompt, seed, and parameters count as one generation:

* First request: Generates and caches the image (billed)
* Subsequent requests: Served from cache (free)

### Blueprint reuse

Using consistent blueprints minimizes unique generations. Design your blueprints to maximize cache hits across your application.

### Engine selection

For high-volume use cases, Stable Diffusion engines are significantly cheaper:

* **DALL-E 2**: $0.016-$0.020 per image
* **Stable Diffusion**: $0.001-$0.030 per image

Choose Stable Diffusion v1.5 or v2.1 at 512px for the most cost-effective generation at \$0.001 per image.

## What's included

* **No minimum commitment**
* **Pay only for generations** (cached requests are free)
* **Token authentication** included at no extra cost
* **Global CDN delivery** for cached images
