22th February 2026: Model loading change
See more here: https://huggingface.co/Kijai/LTXV2_comfy Will update the workflows asap to reflect the changes in ComfyUI model loader logic.
And if you have some experience with nodes, see the link above on what to change, if you want to do yourself. (basically just swapping out the main model loader with a new one)
Update: ComfyUI made a temporary "fix" so that the old workflows still work for now. Eventually you will need to use the new updated workflows though with new model loaders. https://github.com/Comfy-Org/ComfyUI/pull/12605
In process of updating my workflows to reflect the changes
The workflows are based on the extracted models from https://huggingface.co/Kijai/LTXV2_comfy The extracted models might run easier on your 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)

Main split models used in these workflows (LTX-2 dev & distilled safetensor and GGUF, embeddings, audio and video vae): https://huggingface.co/Kijai/LTXV2_comfy

Needed nodes:
https://github.com/kijai/ComfyUI-KJNodes (NB! Must be up to date for LTX-2 support)
https://github.com/city96/ComfyUI-GGUF (NB! Must be up to date for LTX-2 support)
ComfyUI itself must be updated to very latest
