# SD_4XUpscale_Conditioning - ComfyUI Built-in Node Documentation

> The SD4XUpscaleConditioning node prepares conditioning data for upscaling images with diffusion models.

The SD\_4XUpscale\_Conditioning node prepares conditioning data for upscaling images with diffusion models. It scales the input images by a chosen ratio, adds optional noise augmentation, and returns modified positive and negative conditioning together with an empty latent for the upscaled size.

## Inputs

| Parameter            | Description                                                                                                          | Data Type    | Required | Range                  |
| -------------------- | -------------------------------------------------------------------------------------------------------------------- | ------------ | -------- | ---------------------- |
| `images`             | Input images to be upscaled.                                                                                         | IMAGE        | Yes      | -                      |
| `positive`           | Positive conditioning data that guides the generation toward desired content.                                        | CONDITIONING | Yes      | -                      |
| `negative`           | Negative conditioning data that steers the generation away from unwanted content.                                    | CONDITIONING | Yes      | -                      |
| `scale_ratio`        | Multiplier applied to the input image dimensions when preparing the upscaled conditioning and latent (default: 4.0). | FLOAT        | Yes      | 0.0 - 10.0 (step 0.01) |
| `noise_augmentation` | Amount of noise to add during the upscaling process (default: 0.0).                                                  | FLOAT        | Yes      | 0.0 - 1.0 (step 0.001) |

Note: `noise_augmentation` is an advanced parameter, shown in the node interface under the "Advanced" toggle.

## Outputs

| Output Name | Description                                                                                        | Data Type    |
| ----------- | -------------------------------------------------------------------------------------------------- | ------------ |
| `positive`  | Modified positive conditioning with the scaled image data and noise augmentation settings applied. | CONDITIONING |
| `negative`  | Modified negative conditioning with the scaled image data and noise augmentation settings applied. | CONDITIONING |
| `latent`    | Empty latent representation matching the upscaled dimensions.                                      | LATENT       |
