SkipLayerGuidanceDiT - ComfyUI Built-in Node Documentation

Enhances guidance towards detailed structure by using another set of CFG negative with skipped layers. This generic version of SkipLayerGuidance can be used on every DiT model and is inspired by Perturbed Attention Guidance. The original experimental implementation was created for SD3.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The model to apply skip layer guidance to	MODEL	Yes	-
`double_layers`	Comma-separated layer numbers for double blocks to skip (default: “7, 8, 9”)	STRING	Yes	-
`single_layers`	Comma-separated layer numbers for single blocks to skip (default: “7, 8, 9”)	STRING	Yes	-
`scale`	Guidance scale factor (default: 3.0)	FLOAT	Yes	0.0 - 10.0
`start_percent`	Starting percentage for guidance application (default: 0.01)	FLOAT	Yes	0.0 - 1.0
`end_percent`	Ending percentage for guidance application (default: 0.15)	FLOAT	Yes	0.0 - 1.0
`rescaling_scale`	Rescaling scale factor to adjust the output magnitude (default: 0.0, meaning no rescaling)	FLOAT	Yes	0.0 - 10.0

Note: If both double_layers and single_layers are empty (contain no layer numbers), the node returns the original model without applying any guidance.
