 I reccomend using an up-to-date ComfyUI. As of https://github.com/comfyanonymous/ComfyUI/commit/8b275ce5be29ff7d847c3c4c2f3fea1faa68e07b ComfyUI will also automatically detect that the model is V-Prediction/ZSNR and set it for you.
 If for some reason the autodetection doesn't work or you are on an older ComfyUI, use the ModelSamplingDiscrete node to set V-Prediction and ZSNR.
 Alternatively your option is an up-to-date Forge/ReForge as they automatically detect the `vpred` and `tznsr` key I've added to the state_dict of both models and inference as V-Prediction/ZSNR. Forge currently doesn't have a RescaleCFG extension built in, but ReForge does. However I have included a backport of RescaleCFG for Forge in this repo that may work unless the code has changed since creating it. Extract it into extensions-builtin.
+Another option is A1111's dev branch, as it also has auto-detection of V-Prediction SDXL checkpoints from my understanding.
