The workflows are based on the extracted models from https://huggingface.co/Kijai/LTXV2_comfy The extracted models runs easier on the computer (as separate files), as well as GGUF support etc
(but you can easily swap out the model loader for the ComfyUI default model loader if you want to load the checkpoint with "all in one" vae built-in etc)
