# WavespeedImageUpscaleNode - ComfyUI Built-in Node Documentation

> Complete documentation for the WavespeedImageUpscaleNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The WaveSpeed Image Upscale node uses an external AI service to increase the resolution and quality of an image. It takes a single input photo and upscales it to a higher target resolution, such as 2K, 4K, or 8K, producing a sharper and more detailed result.

## Inputs

| Parameter           | Description                                                                                            | Data Type | Required | Range                          |
| ------------------- | ------------------------------------------------------------------------------------------------------ | --------- | -------- | ------------------------------ |
| `model`             | The AI model to use for upscaling. "SeedVR2" and "Ultimate" offer different quality and pricing tiers. | STRING    | Yes      | `"SeedVR2"`<br />`"Ultimate"`  |
| `image`             | The input image to be upscaled. Exactly one image is required.                                         | IMAGE     | Yes      |                                |
| `target_resolution` | The desired output resolution for the upscaled image.                                                  | STRING    | Yes      | `"2K"`<br />`"4K"`<br />`"8K"` |

**Note:** This node requires exactly one input image. Providing a batch of images will result in an error.

## Outputs

| Output Name | Description                                 | Data Type |
| ----------- | ------------------------------------------- | --------- |
| `image`     | The upscaled, high-resolution output image. | IMAGE     |
