DualModelGuider - ComfyUI Built-in Node Documentation

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
