This model does not work with native ComfyUI INT8, and will need to be converted with this tool.
Unless you already downloaded this model, I recommend finding a more recent INT8 quant from Silveroxides to avoid having to do this.
INT8 ConvRot checkpoints for use with https://github.com/BobJohnson24/ComfyUI-INT8-Fast
Quick quality comparison with https://huggingface.co/Winnougan/Sulphur-2-LTX-2.3 against BF16
Beware of low sample size (8 samples), this just exists to show its very roughly in the same-ish ballpark.
