# DualCFGGuider - ComfyUI Built-in Node Documentation

> The Dual CFG Guider node creates a guidance system for sampling that uses two conditioning inputs together with one negative conditioning input.

The Dual CFG Guider node creates a guidance system for sampling that uses two conditioning inputs together with one negative conditioning input. It applies two separate guidance scales to control how strongly each conditioning influences the generated result, and it supports two ways of combining those scales: "regular" and "nested".

## Inputs

| Parameter            | Description                                                                                                                | Data Type    | Required | Range                   |
| -------------------- | -------------------------------------------------------------------------------------------------------------------------- | ------------ | -------- | ----------------------- |
| `model`              | The model to use for guidance                                                                                              | MODEL        | Yes      | -                       |
| `cond1`              | The first positive conditioning input                                                                                      | CONDITIONING | Yes      | -                       |
| `cond2`              | The second conditioning input, used as the reference between the first positive conditioning and the negative conditioning | CONDITIONING | Yes      | -                       |
| `negative`           | The negative conditioning input                                                                                            | CONDITIONING | Yes      | -                       |
| `cfg_conds`          | Guidance scale applied to the first positive conditioning (default: 8.0)                                                   | FLOAT        | Yes      | 0.0 - 100.0             |
| `cfg_cond2_negative` | Guidance scale applied between the second conditioning and the negative conditioning (default: 8.0)                        | FLOAT        | Yes      | 0.0 - 100.0             |
| `style`              | The guidance style to apply (default: "regular"). When set to "nested", the guidance is applied in a nested fashion        | COMBO        | Yes      | "regular"<br />"nested" |

Note: In `regular` style, `cfg_cond2_negative` is applied between `cond2` and `negative`, and `cfg_conds` is applied between `cond1` and `cond2`. In `nested` style, `cfg_conds` is applied first between `cond1` and `cond2`, and the resulting prediction is then guided away from `negative` using `cfg_cond2_negative`.

Note: In `regular` style, when `cfg_cond2_negative` is equal to 1.0 the negative conditioning is skipped, and when `cfg_conds` is also equal to 1.0 the second conditioning is skipped as well. This reduces the number of model evaluations performed.
