Accelerating Wan 2.2 video generation by 16.8× via 4-step diffusion distillation
Reducing Wan 2.2 A14B video generation latency from 809 seconds to 48 seconds per 5-second clip on an NVIDIA A100 GPU. Evaluates 4-step Phased-DMD distillation LoRA adapters across 13 test scenes without quality loss or custom CUDA kernels.
