使用方法
需要搭配插件 eastmoe/Comfyui-Hunyuan-Image3 使用。
- 将
diffusion_models/hunyuan_image_3_instruct_moe_w4a8.safetensors放入ComfyUI/models/diffusion_models/ - 将
vae/hunyuan_image_3_vae_fp32.safetensors放入ComfyUI/models/vae/
量化精度
相对 RMSE（按专家/层统计的百分位分布）：
| 指标 | p50 相对 RMSE | p95 | p99 | 最大值 |
|---|---|---|---|---|
| Gate/Up 权重 | 7.314% | 7.316% | 7.316% | 7.318% |
| Down 权重 | 7.312% | 7.315% | 7.315% | 7.317% |
| 完整专家前向 | 12.547% | 13.028% | 13.192% | 13.370% |
最差完整专家的余弦相似度为 0.99102。
详细逐层数据见 hyi3_w4a8_checkpoint_error.json，可通过 evaluate_hyi3_expert_quant.py 复现。
