# Dual Model CFG Guider

This node allows you to use two different models during the guided CFG sampling process: one model for the positive (conditional) pass and a separate model for the negative (unconditional) pass. When no negative model is provided, it behaves like a standard CFG guider using a single model.

## Inputs

| Parameter        | Description                                                                                                         | Data Type    | Required | Range                    |
| ---------------- | ------------------------------------------------------------------------------------------------------------------- | ------------ | -------- | ------------------------ |
| `model`          | Model used for the positive (conditional) pass.                                                                     | MODEL        | Yes      |                          |
| `model_negative` | Model used for the negative (unconditional) pass. Use the same model for ordinary CFG.                              | MODEL        | No       |                          |
| `positive`       | The positive conditioning input.                                                                                    | CONDITIONING | Yes      |                          |
| `cfg`            | The CFG scale value (default: 4.0).                                                                                 | FLOAT        | Yes      | 0.0 to 100.0 (step: 0.1) |
| `negative`       | Negative conditioning run on the negative model. Leave unconnected for a text-free (image-only) unconditional pass. | CONDITIONING | No       |                          |

## Outputs

| Output Name | Description                                                                                | Data Type |
| ----------- | ------------------------------------------------------------------------------------------ | --------- |
| `GUIDER`    | A guider object configured with the specified models and conditioning for use in sampling. | GUIDER    |
