Video generation gets 120x faster on one GPU, inside Nvidia's hybrid attention breakthrough
Nvidia Research's SANA-Video 2.0 combines linear and periodic softmax attention in a 3:1 ratio to run 120x faster than Wan 2.2 on one H100. The hybrid design recovers full-rank expressiveness while keeping inference at 13 seconds for a 720p clip. The caveats: the benchmarks stop at 720p and bundle the attention change with proprietary optimizations.
