CFGGuider - ComfyUI Built-in Node Documentation

The CFG Guider node creates a guidance system for controlling the sampling process in image generation. It takes a model along with positive and negative conditioning inputs, then applies a classifier-free guidance scale to steer the generation toward desired content while avoiding unwanted elements. This node outputs a guider object that can be used by sampling nodes to control the image generation direction.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The model to be used for guidance	MODEL	Yes	-
`positive`	The positive conditioning that guides the generation toward desired content	CONDITIONING	Yes	-
`negative`	The negative conditioning that steers the generation away from unwanted content	CONDITIONING	Yes	-
`cfg`	The classifier-free guidance scale that controls how strongly the conditioning influences the generation (default: 8.0)	FLOAT	Yes	0.0 to 100.0
