JST-2

Viggle's second-generation "physics-native" world foundation model, announced 19 October. JST (Joint Space-and-Time) represents a world as persistent 3D atoms, each with an xyz position plus learned attribute and dynamics vectors, decoded to images or 3D Gaussian splats. It builds a 3D scene in about one second on an NVIDIA B200 for under $0.01, takes up to 64 input views, and generates animation-ready characters and full-body motion from text or video. In blind human tests Viggle reports wins over Meshy 7.1, Tripo H3.1, Cartwheel and DeepMotion (self-reported). It is free to try in PINOC and available by API and MCP; JST-3 with learned physics is in development.
