SANA-Video 2.0 Generates 720p Video on One GPU with Linear‑Softmax Attention
SANA-Video 2.0 uses a hybrid linear‑softmax attention scheme to produce 720p, 5‑second clips on a single H100 GPU in under 14 seconds. The 5B and 14B models match full‑softmax video diffusion quality while cutting latency by up to 120×, opening high‑resolution video generation to far smaller hardware.
