Tsinghua's Zhao Hao: The Key to Physical AI Lies in 4D Controllable World Models

In an interview, Tsinghua University assistant professor Zhao Hao argues that true world models for autonomous driving and robotics must be native 4D, integrating space, time, physics, and interaction. He outlines the evolution of multimodal models from language to 4D and highlights recent team achievements including Dexora and Trellis.2.
