# ModelMergeLTXV - ComfyUI Built-in Node Documentation

> The ModelMergeLTXV node merges two LTXV models by blending their matching components.

The ModelMergeLTXV node merges two LTXV models by blending their matching components. Each model part — such as transformer blocks, projection layers, and the scale shift table — can be blended separately with its own weight, giving fine control over how the two models are combined.
