# CFGOverride - ComfyUI Built-in Node Documentation

> The CFG Override node overrides the CFG (Classifier-Free Guidance) scale to a fixed value over a percentage (sigma) range of the sampling process.

The CFG Override node overrides the CFG (Classifier-Free Guidance) scale to a fixed value over a percentage (sigma) range of the sampling process. When multiple CFG Override nodes are used, the override nearest the sampler wins on overlapping ranges.

## Inputs

| Parameter       | Description                                                                                     | Data Type | Required | Range                    |
| --------------- | ----------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------ |
| `model`         | The model to apply the CFG override to.                                                         | MODEL     | Yes      |                          |
| `cfg`           | The fixed CFG scale value to use during the override range. Default: 1.0.                       | FLOAT     | Yes      | 0.0 to 100.0 (step: 0.1) |
| `start_percent` | The starting point of the override range as a percentage of the sampling process. Default: 0.0. | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.001) |
| `end_percent`   | The ending point of the override range as a percentage of the sampling process. Default: 1.0.   | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.001) |

## Outputs

| Output Name | Description                                      | Data Type |
| ----------- | ------------------------------------------------ | --------- |
| `MODEL`     | The model with the CFG override wrapper applied. | MODEL     |
