> [!CAUTION]
> **NOT WORKING — Work in progress.** The paper's algorithm was designed for DiffSynth-Studio and does not translate directly to ComfyUI's k-diffusion sampling framework. Images are corrupted or artifacted at high CFG scales (e.g. cfg=12 on SDXL). Do not use this node in production workflows until this notice is removed.
