ModelMergeSubtract - ComfyUI Built-in Node Documentation

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

This node is designed for advanced model merging operations, specifically to subtract the parameters of one model from another based on a specified multiplier. It enables the customization of model behaviors by adjusting the influence of one model’s parameters over another, facilitating the creation of new, hybrid models.

Inputs

Parameter	Data Type	Description
model1	MODEL	The base model from which parameters will be subtracted.
model2	MODEL	The model whose parameters will be subtracted from the base model.
multiplier	FLOAT	A floating-point value that scales the subtraction effect on the base model’s parameters.

Outputs

Parameter	Data Type	Description
model	MODEL	The resulting model after subtracting the parameters of one model from another, scaled by the multiplier.
