CLIPMergeSubtract - ComfyUI Built-in Node Documentation

The CLIPMergeSubtract node performs model merging by subtracting the weights of one CLIP model from another. It creates a new CLIP model by cloning the first model and then subtracting the key patches from the second model, with an adjustable multiplier to control the subtraction strength. This allows for fine-tuned model blending by removing specific characteristics from the base model.

Inputs

Parameter	Description	Data Type	Required	Range
`clip1`	The base CLIP model that will be cloned and modified	CLIP	Yes	-
`clip2`	The CLIP model whose key patches will be subtracted from the base model	CLIP	Yes	-
`multiplier`	Controls the strength of the subtraction operation (default: 1.0)	FLOAT	Yes	-10.0 to 10.0 (step: 0.01)

Note: The node excludes .position_ids and .logit_scale parameters from the subtraction operation, regardless of the multiplier value.

Outputs

Output Name	Description	Data Type
`clip`	The resulting CLIP model after subtracting the second model’s weights from the first	CLIP
