CFGOverride - ComfyUI Built-in Node Documentation

The CFG Override node allows you to set a fixed CFG (Classifier-Free Guidance) scale value for a specific range of the sampling process, defined as a percentage of the total steps. When multiple CFG Override nodes are connected, the one closest to the sampler in the chain takes priority for 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
`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
`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
