Viggle unveils JST-2, a world model built in 3D
Viggle AI released JST-2, which it calls “the world’s first full-stack physics-native world foundation model.” Rather than learning from pixels or video like many world models, Viggle says it built the entire model stack in 3D. According to the company, JST-2 can “generate a 3D scene in seconds” and expand it in real time and also create animation ready characters. Viggle says scene collisions still use rule based physics, with learned physics planned for a future JST-3. These are Viggle’s own claims.
