Wan2.2 I2V 14B: HiFi Surgical FP8 & BF16 (ComfyUI Optimized) This model follows the Wan AI Software License Agreement. Please refer to the original repository for usage restrictions. This repository provides two high performance versions of Wan2.2 I2V 14B , meticulously optimized for the ComfyUI ecosystem. We offer a standard BF16 version and a specialized HiFi Surgical FP8 mixed precision version. Original Project : Video Reason Wan2.2 Original Weights : HuggingFace VBVR Wan2.2 💎 The HiFi Surgical Optimization Strategy Unlike generic "one click" quantization scripts that often cause visual degradation in Wan2.2, our HiFi Surgical FP8 version uses a data driven, diagnostic led approach to preserve cinematic quality. 1. Layer Wise SNR Calibration We performed a deep medical grade scan on all 406 linear weight tensors of the FP32 Master. Only layers maintaining an SNR (Signal to Noise Ratio) 31.5dB were converted to FP8. This ensures that the mathematical "soul" of the model remains intact. 2. High Outlier Protection Wan2.2 weights are notoriously "fragile" with sharp numerical peaks. Our strategy identifies layers with a high Outlier Index (Max/Std deviation 12) and locks them in B…
