This is meant for testing only, with the ability to use same models and python env as ComfyUI, it is NOT a proper ComfyUI implementation!

• As this is only a wrapper, it's not compatible with anything else in ComfyUI, besides input preprocessing and being able to load and convert most models for the Diffusers pipeline
• Ohe ratio between 1.5 and SDXL resolution also has to be exactly 1:2
• Some ControlNets/LoRAs won't load, and results with some combos seem broken

This repository is the official implementation of X-Adapter.

X-Adapter: Adding Universal Compatibility of Plugins for Upgraded Diffusion Model
Lingmin Ran, Xiaodong Cun, Jia-Wei Liu, Rui Zhao, Song Zijie, Xintao Wang, Jussi Keppo, Mike Zheng Shou

X-Adapter enable plugins pretrained on old version (e.g. SD1.5) directly work with the upgraded Model (e.g., SDXL) without further retraining.
