Viggle's JST-2 builds explorable 3D worlds from a single prompt
Viggle just introduced JST-2, a physics-native world model that turns text prompts or images into interactive 3D scenes in about one second. It tracks persistent physical tokens across space, allowing generated characters to deform and move naturally without manual rigging. It renders directly in the browser via 3D Gaussian splatting, putting full 3D environment generation within reach for everyone.
