# ImageUpscaleWithModel - ComfyUI Built-in Node Documentation

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

This node is designed for upscaling images using a specified upscale model. It efficiently manages the upscaling process by adjusting the image to the appropriate device, optimizing memory usage, and applying the upscale model in a tiled manner to prevent potential out-of-memory errors.

## Inputs

| Parameter       | Comfy dtype     | Description                                                                                                                   |
| --------------- | --------------- | ----------------------------------------------------------------------------------------------------------------------------- |
| `upscale_model` | `UPSCALE_MODEL` | The upscale model to be used for upscaling the image. It is crucial for defining the upscaling algorithm and its parameters.  |
| `image`         | `IMAGE`         | The image to be upscaled. This input is essential for determining the source content that will undergo the upscaling process. |

## Outputs

| Parameter | Data Type | Description                                                                                                                                              |
| --------- | --------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `image`   | `IMAGE`   | The upscaled image, processed by the upscale model. This output is the result of the upscaling operation, showcasing the enhanced resolution or quality. |
