ControlNet Models (ConvRot INT8)
High-fidelity ConvRot INT8 quantized weights for multi-condition ControlNet models across diverse generative architectures (Illustrious-XL / SDXL, SDXL 1.0, Qwen-Image, and FLUX.1-dev).
🌟 Model Overview
This repository hosts high-quality ConvRot INT8 quantized weights for all-in-one ControlNet Union models. By applying orthogonal Hadamard rotation prior to per-channel INT8 quantization, these models effectively eliminate activation outlier distortion and drastically reduce VRAM and disk footprint while preserving precise structural control fidelity:
- CN-anytest4_illustrious2 (Variants A & B): Multi-purpose all-in-one Anytest v4 ControlNet models fine-tuned for Illustrious-XL / SDXL by 2vXpSwA7, offering high-precision anime and illustration structure guiding.
- controlnet-union-pro-max-sdxl-1.0: The comprehensive all-in-one ControlNet Union model for SDXL 1.0 by xinsir, supporting 10+ control conditions in a single compact file.
- Qwen-Image-2512-Fun-Controlnet-Union-2602: Multi-condition ControlNet Union model (5 layer blocks) for the Qwen-Image-2512 architecture.
- FLUX.1-dev-ControlNet-Union-Pro-2.0: Next-generation unified 7-in-1 ControlNet for the FLUX.1-dev architecture by Shakker Labs.

🛠️ Key Features
- All-in-One Multi-Condition Control: Unified architectures enabling single or blended conditioning inputs (Pose, Depth, Lineart, Canny, Tile, etc.) without switching heavy checkpoints during workflow execution.
- ConvRot INT8 Precision: Leverages orthogonal Hadamard rotations to redistribute channel-wise outlier spikes uniformly across dimensions, preventing quantization error buildup in deep control layers.
- VRAM & Storage Optimization: Slashes VRAM consumption and disk footprint by ~50% to 70% compared to unquantized FP16 checkpoints, allowing seamless multi-ControlNet workflows on consumer GPUs.
