This is a mixed FP8/BF16 quantized release of Alibaba PAI's FLUX.2-dev-Fun-Controlnet-Union-2602, prepared for practical use with FLUX.2-dev in ComfyUI.

It preserves the Union ControlNet's multi-purpose conditioning capabilities—including OpenPose, depth, edge/HED, and other control inputs—while substantially reducing the model's storage and memory footprint. The quantization was calibration-based and validated against the original model with visually indistinguishable output in our test workflows.
