fruesome · reddit · 2026-09-24
Alibaba's PAI team has released Qwen-Image-2.1-Fun-ControlNet-Union on Hugging Face, a ControlNet-Union branch for Qwen-Image 2.1 (a flow-matching text-to-image DiT).
Key points:
- A single checkpoint drives 8 structural control conditions — Canny, Depth, Grayscale, HED, Lineart, MLSD, Pose, Scribble — plus image inpainting, with no per-condition weights
- The checkpoint holds only the control branch (controlimgin plus 16 control blocks, 7.0 GB), loaded on top of the base Qwen-Image 2.1 transformer
- ComfyUI support is in progress: Kijai has an open PR (Comfy-Org/ComfyUI#16519)
