ModelMergeSD35_Large - ComfyUI Built-in Node Documentation - ComfyUI

The ModelMergeSD35_Large node merges two Stable Diffusion 3.5 Large models by blending specific internal components of the second model into the first. Each component has an independent blend value, giving fine-grained control over how strongly that component contributes to the resulting merged model.
