ModelMergeBlocks - ComfyUI Built-in Node Documentation

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

ModelMergeBlocks is designed for advanced model merging operations, allowing for the integration of two models with customizable blending ratios for different parts of the models. This node facilitates the creation of hybrid models by selectively merging components from two source models based on specified parameters.

Inputs

Parameter	Data Type	Description
model1	MODEL	The first model to be merged. It serves as the base model onto which patches from the second model are applied.
model2	MODEL	The second model from which patches are extracted and applied to the first model, based on the specified blending ratios.
input	FLOAT	Specifies the blending ratio for the input layer of the models. It determines how much of the second model’s input layer is merged into the first model.
middle	FLOAT	Defines the blending ratio for the middle layers of the models. This parameter controls the integration level of the models’ middle layers.
out	FLOAT	Determines the blending ratio for the output layer of the models. It affects the final output by adjusting the contribution of the second model’s output layer.

Outputs

Parameter	Data Type	Description
model	MODEL	The resulting merged model, which is a hybrid of the two input models with patches applied according to the specified blending ratios.
