ModelMergeCosmosPredict2_14B - ComfyUI Built-in Node Documentation - ComfyUI

The ModelMergeCosmosPredict2_14B node combines two AI models into one by blending their matching internal components. It lets you control how much of the second model is mixed into the first by adjusting a separate weight for each embedder, block, and the final layer.
