During the opening ceremony of the General World Model Beijing Key Laboratory, GigaAI founder and CEO Huang Guan said artificial general intelligence must go beyond language intelligence and also understand, generate, predict, and act in physical 3D space, which depends on breakthroughs in general world models. He introduced GigaAI's L1-L5 tiered system for general world models and noted that world models are relatively mature at L1 and show promise at L2 but have not yet broken through, still lagging language models overall.
