Summary Report

Viggle's JST-2 generates 3D scenes and moving characters natively in 3D from one architecture.

  • 01. Built in 3D rather than pixel or video space
  • 02. Scenes in seconds, real-time expansion, characters with motion, language control
Viggle has released JST-2, which it calls the first full-stack physics-native world foundation model. Rather than learning from pixels and video like most world models, it's built in 3D from the ground up, generating actual scenes rather than flat frames. It creates a 3D scene in seconds, expands it in real time, and generates characters with motion built in, directed in plain language. There's no technical paper or independent benchmark yet.
