NVIDIA appears to have released SANA-WM, a 2.6B-parameter open-source world model for generating controllable, physics-rich, high-fidelity worlds, according to Brian Roemmele (@BrianRoemmele) in a post on X.

Roemmele characterized SANA-WM as "a blazing-fast 2.6B-parameter open-source world model that does not just generate video... it creates controllable, physics-rich, high-fidelity worlds on demand." The post includes a short demo clip. RuntimeWire has not independently verified the release details.
The post did not include links to a code repository, paper, model card, or license, and it did not specify hardware requirements or an availability timeline. We will update if NVIDIA publishes official documentation.
If accurate, an open-source, small-footprint world model with controllability could be significant for simulation and content workflows, from game prototyping and synthetic data to robotics sim-to-real and VFX previz, especially if it runs efficiently on commodity GPUs.
