Zenithon raises $10M for physics world models

Zenithon raised $10 million for world models targeting extreme physics, including fusion reactors, rockets, and semiconductor manufacturing. The London lab says its models could explore one million design points in the time a conventional simulation explores one, while the round funds hiring and compute for releases every three months. For teams running expensive physics workloads, file this as a specialized-model bet—not a solver replacement—until local error and uncertainty tests show the speedup preserves design rankings; AMD’s World Labs deal makes portability a separate buying question.
