CFGOverride - ComfyUI Built-in Node Documentation - ComfyUI

The CFG Override node overrides the CFG (Classifier-Free Guidance) scale to a fixed value over a percentage (sigma) range of the sampling process. When multiple CFG Override nodes are used, the override nearest the sampler wins on 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 (step: 0.1)
`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 (step: 0.001)
`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 (step: 0.001)

Outputs

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