Hi Jon, thank you for your interest! The project is essentially two parts: a low level physics engine that integrates a wide range of solvers for simulating materials with different physical properties, and a upper level LLM/VLM agent that uses the physics engine as tools to compose worlds and generate other modalities of data. The generative agent incorporates multiple generative modules handling different modalities in a modular way, and the high-level goal is instead of generating everything end-to-end, we generate them in a structured way and all of them collectively form a physical world :) Let me know if you want to dive deeper
