Upscale image with minimal alterations to 4K resolution. This node uses Stability AI's conservative upscaling to increase image resolution while preserving the original content and making only subtle changes.

## Inputs

| Parameter         | Data Type | Required | Range        | Description                                                                                                                                                                     |
| ----------------- | --------- | -------- | ------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `image`           | IMAGE     | Yes      | -            | The input image to be upscaled                                                                                                                                                  |
| `prompt`          | STRING    | Yes      | -            | What you wish to see in the output image. A strong, descriptive prompt that clearly defines elements, colors, and subjects will lead to better results. (default: empty string) |
| `creativity`      | FLOAT     | Yes      | 0.2-0.5      | Controls the likelihood of creating additional details not heavily conditioned by the init image. (default: 0.35)                                                               |
| `seed`            | INT       | Yes      | 0-4294967294 | The random seed used for creating the noise. (default: 0)                                                                                                                       |
| `negative_prompt` | STRING    | No       | -            | Keywords of what you do not wish to see in the output image. This is an advanced feature. (default: empty string)                                                               |

## Outputs

| Output Name | Data Type | Description                         |
| ----------- | --------- | ----------------------------------- |
| `image`     | IMAGE     | The upscaled image at 4K resolution |
