Instead of generating videos, Viggel’s JST-2 outputs 3D characters that move in their environment. It combines character, motion, and scene generation into a single model: • Upload a photo and it creates the character • Describe how you want it to move, or upload a reference video • Generate the world around it from text or a photo
Today we are releasing JST-2, the world's first full-stack physics-native world foundation model. Many world models learn in pixel/video space. We went back to first principles and built the entire model stack in 3D. Generate a 3D scene in seconds and expand it in real time. Create characters with motion built in, all through one general architecture.
