## Overview

This node adjusts the noise scale used during model sampling. It allows you to set a specific noise scale value, which controls the amount of noise applied to the model's sampling process.

## Inputs

| Parameter     | Data Type | Required | Range                    | Description                                                                               |
| ------------- | --------- | -------- | ------------------------ | ----------------------------------------------------------------------------------------- |
| `model`       | MODEL     | Yes      | -                        | The model to apply the noise scale adjustment to.                                         |
| `noise_scale` | FLOAT     | Yes      | 0.0 to 64.0 (step: 0.01) | Absolute training noise scale. For example HiDream-O1 base: 8.0, dev: 7.5. (default: 1.0) |

## Outputs

| Output Name | Data Type | Description                                          |
| ----------- | --------- | ---------------------------------------------------- |
| `MODEL`     | MODEL     | The modified model with the new noise scale applied. |
