WAN 2.2 I2V A14B - LightX2V 4-Step Distillation LoRAs (Rank-Reduced)
SVD rank-reduced versions of the lightx2v/Wan2.2-Distill-Loras I2V A14B 4-step LoRAs.
Variants
| Rank | Avg Reconstruction Error | Energy Retained | Size (HN/LN) | Speed |
|---|---|---|---|---|
| 32 | ~40% | ~83% | 307 / 358 MB | ~2-3 min (matches Comfy-Org) |
| 48 | ~27% | ~93% | 455 / 532 MB | ~4-5 min |
| 64 (original) | 0% | 100% | 606 / 706 MB | ~6-11 min |
Processing
- Rank reduction via exact SVD (QR + inner matrix SVD)
- Stripped non-standard keys:
.diff_m,norm_k_img,.diff(1D norm),.diff_b - Compatible with WGP / mmgp LoRA loader
Usage
Each variant has high_noise and low_noise LoRAs for the two-phase distillation schedule.
