| The workflows are based on the extracted models from https://huggingface.co/Kijai/LTX2.3_comfy |
| The extracted models might run easier on your computer (as separate files). |
| (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) |
