SANA-Video 2.0 发布

Emad (@EMostaque) 转发了 Enze Xie (@xieenze_jr) 的帖子： 🚀 SANA-Video 2.0 is here! A full-stack optimized video model designed for efficiency — while still delivering high quality. We combine a hybrid architecture closely related to the recent Kimi K3 design, adopt Self-Flow from FLUX 3, and further accelerate it with our own Sol-Engine. Key technical ingredients: 🧠 Hybrid Linear–Softmax Attention 3 gated linear layers + 1 gated-softmax anchor (75% linear / 25% softmax) 🧱 Block Attention Residuals (AttnRes) Boosts deep-layer effective rank by ~12% 🏗️ Unified 5B & 14B models Trained from scratch under very limited resources: • 5B → only 16 nodes of H100 • 14B → 48 nodes of B200 Results 📊 • 84.30 VBench Total • 3.2× faster DiT forward than matched full-softmax at 720p/60s • 720p/5s in 13.06s on a single H100 with Sol-Engine • 120× faster than Wan 2.2-A14B under the same one-H100 setup SANA-Video 2.0 shows that high-quality 720p video generation can be both efficient and practical on a single GPU. 🎬 Project: https://t.co/40uvReE9oE 📄 Paper: https://t.co/cmJZhU64pp 💻 Code: https://t.co/3UlHHqdv0Y Proud of the team! 🎉 More details below 🧵 https://video.twimg.com/amplify_video/2080515508412256256/vid/avc1/1280x720/JRNaonM3vhC0NEeX.mp4?tag=29
