DualCFGGuider - ComfyUI Built-in Node Documentation

The DualCFGGuider node creates a guidance system for dual classifier-free guidance sampling.

The DualCFGGuider node creates a guidance system for dual classifier-free guidance sampling. It combines two conditioning inputs with one negative conditioning input and applies two separate guidance scales to control how strongly each conditioning influences the generated output. It supports two styles of combining these guidance 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" "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.

Outputs
