Viggle JST-2

Viggle JST-2 is a physics-native world foundation model that generates 3D scenes, characters, and full-body motion within one shared world. Scenes can be created in about a second, characters are generated from a single image or text prompt with motion built in, and motion can be driven by text or video. It is available through the free PINOC browser app, an API, or MCP integration with agents like Claude Code.
