# Sd4xupscaleConditioning - ComfyUI Built-in Node Documentation

> Complete documentation for the Sd4xupscaleConditioning node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node specializes in enhancing the resolution of images through a 4x upscale process, incorporating conditioning elements to refine the output. It leverages diffusion techniques to upscale images while allowing for the adjustment of scale ratio and noise augmentation to fine-tune the enhancement process.

## Inputs

| Parameter            | Description                                                                                                                                                             | Comfy dtype    |
| -------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------- |
| `images`             | The input images to be upscaled. This parameter is crucial as it directly influences the quality and resolution of the output images.                                   | `IMAGE`        |
| `positive`           | Positive conditioning elements that guide the upscale process towards desired attributes or features in the output images.                                              | `CONDITIONING` |
| `negative`           | Negative conditioning elements that the upscale process should avoid, helping to steer the output away from undesired attributes or features.                           | `CONDITIONING` |
| `scale_ratio`        | Determines the factor by which the image resolution is increased. A higher scale ratio results in a larger output image, allowing for greater detail and clarity.       | `FLOAT`        |
| `noise_augmentation` | Controls the level of noise augmentation applied during the upscale process. This can be used to introduce variability and improve the robustness of the output images. | `FLOAT`        |

## Outputs

| Parameter  | Description                                                                                                                  | Data Type      |
| ---------- | ---------------------------------------------------------------------------------------------------------------------------- | -------------- |
| `positive` | The refined positive conditioning elements resulting from the upscale process.                                               | `CONDITIONING` |
| `negative` | The refined negative conditioning elements resulting from the upscale process.                                               | `CONDITIONING` |
| `latent`   | A latent representation generated during the upscale process, which can be utilized in further processing or model training. | `LATENT`       |
