NVIDIA Releases SANA-WM: 2.6B Open-Source World Model Achieves Minute-Scale Video at 36× Efficiency Gain

NVIDIA has released SANA-WM, a 2.6-billion-parameter open-source world model capable of generating one-minute videos at 720p resolution, delivering a 36× throughput advantage over previous open-source baselines while running on a single consumer GPU. Unveiled in May 2026 through a collaboration with MIT and Tsinghua University, the model represents a significant step forward in making advanced video generation accessible to researchers and developers without proprietary dependencies.
