Fysics launches differentiable physics engine and Physical-AI stack
Fysics released its differentiable physics engine with MoziSim training software, the OmniFysics model and evaluation benchmarks for embodied-AI development.

Evidence notes
- The engine supports coupled rigid-body, soft-body and fluid simulation with differentiable optimisation across the simulation and training loop.
- MoziSim covers scene construction, robot and sensor simulation, training and sim-to-real workflows for humanoids, quadrupeds and robot arms.
- OmniFysics, FysicsWorld and FysicsEval add model and benchmark layers around the simulation stack.
Company context
