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.<h3 id="comfyui">ComfyUI</h3>Use with the JLC Flux2 ControlNet custom nodes:GitHub: <a target="_blank" rel="ugc" href="https://github.com/Damkohler/JLC-Flux2-ControlNet">https://github.com/Damkohler/JLC-Flux2-ControlNet</a>The model should be placed in:<code>ComfyUI/models/controlnet/</code>For technical details, validation information, and provenance, see the accompanying Hugging Face model page.
