What it is
A streaming video generation system that pipelines chunk denoising and cache refresh to emit one chunk per forward round after fill, while preserving long-video quality and motion. Instead of serial chunk denoising plus a separate cache-refresh pass, it lets newer chunks attend to earlier cleaner-but-unfinished chunks and pipelines denoise/store across model replicas for 1F1C continuous output.
Key results
- 134.8 end-to-end FPS and 147.6 DiT FPS on 8 H200s with 4-step WF
- 5-step WF: 81.64 VBench Total vs 81.15 for Rolling Forcing
- Long-video Dynamic 91.45 vs 36.63 for Rolling Forcing; Subject 97.10 vs 92.75
Shows streaming video generation can reach near-real-time throughput without giving up long-horizon motion or subject consistency.
