This is a direct GGUF conversion of the LTXV-13B-0.9.8-dev variant from Lightricks/LTX-Video.
The model files can be used in ComfyUI with the ComfyUI-GGUF custom node. Place the required model(s) in the following folders:
| Type | Name | Location | Download |
|---|---|---|---|
| Main Model | LTXV-13B-0.9.8-dev | ComfyUI/models/diffusion_models | GGUF (this repo) |
| Text Encoder | T5-V1.1-XXL-Encoder | ComfyUI/models/text_encoders | Safetensors / GGUF |
| VAE | LTXV-13B-0.9.8-dev-VAE.safetensors | ComfyUI/models/vae | Safetensors |
The old example workflow from last version should still work, youll just need to switch the vae and the gguf. Example workflow - based on the official example workflow
Notes
As this is a quantized model not a finetune, all the same restrictions/original license terms still apply.
Comfyui now supports the ggufs natively, so you just need to update comfyui to the latest version and if some issues persist update all the nodes in the workflow
Other T5 clips will probably work as well, just use one that you like, you can get them as safetensors or ggufs. The best I tried was the t5 v1.1 xxl one
Loras do work, but you need to follow the steps in the example workflow and dont use torchcompile with loras!
Teacache works with ltx but atm not really good. The rel_l1_thresh only seems to work at 0.01 in my testing and even that causes some noticable quality drops, best leave it disabled.
