Peking University, Tsinghua and Alibaba Open-Source SparkDiffusion for Up to 265x Faster Wan Video Generation

Researchers from Peking University, Tsinghua University, and Alibaba have launched SparkDiffusion, an acceleration framework for video models. In tests, generating a five-second video dropped from 4,769 seconds to 18 seconds on an RTX 5090, achieving a 265-fold speedup. On an H100, the same task fell from 1,757 seconds to 8 seconds, a 220-fold improvement.
