SkipLayerGuidanceDiT - ComfyUI Built-in Node Documentation

Complete documentation for the SkipLayerGuidanceDiT node in ComfyUI. Learn its inputs, outputs, parameters and usage.

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.

Outputs

Output Name	Description	Data Type
model	The modified model with skip layer guidance applied	MODEL
