# CFG Override

The CFG Override node allows you to set a fixed CFG (Classifier-Free Guidance) scale value for a specific range of the sampling process, defined as a percentage of the total steps. When multiple CFG Override nodes are connected, the one closest to the sampler in the chain takes priority for 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 |
| `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   |
| `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   |

## Outputs

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