willeastcott · x · 2026-10-20
Viggle AI released JST-2, which it calls the world's first full-stack physics-native world foundation model.
- Unlike most world models that learn in pixel/video space, the team says it built the entire model stack natively in 3D from first principles.
- It can generate a 3D scene in seconds and expand it in real time, and create characters with built-in motion, all through one general architecture.
- Demos and viewers are powered by PlayCanvas for real-time in-browser exploration.
