Wave Forcing targets one chunk per concurrent round

Wave Forcing (WF) combines chunk-wise causal attention with a staggered denoising pipeline to generate streaming video at one output chunk per concurrent forward round after pipeline fill. On Wan2.1-T2V-1.3B, its five-step version reaches VBench Total 81.64, compared with 81.15 for five-step Rolling Forcing, while substantially increasing measured motion.

The efficiency problem WF addresses comes from the clean-history caching convention used in the study: each chunk needs denoising passes and a separate store pass to refresh its key/value history. That makes even one-step generation require two forward rounds per chunk when executed serially.…
