MiniMax H3 VDN INT8 ConvRot (ComfyUI Version)
This repository provides the INT8 ConvRot quantized linear branch weights for OpenVDN/vdn-minimax-h3.
🚀 Key Improvements:
- ~46% Smaller File Size: Reduced from ~4.3 GB down to ~2.10 GB.
- Lower VRAM: Saves ~4.7 GB of peak VRAM during model loading.
- Near-Lossless Quality: Uses Hadamard Convolutive Rotation (ConvRot group 256) to prevent quantization noise while maintaining original BF16 visual accuracy.
- Fully Compatible: Native support in ComfyUI and
RT Minimax H3 VDN.
