Meta’s star AI scientist Yann LeCun plans to leave for own startup

Meta's chief AI scientist, Yann LeCun, is leaving the company to start his own startup focusing on "world models" AI, which aims to understand the physical world through video and spatial data. This move comes as Meta CEO Mark Zuckerberg revamps the company's AI operations due to falling behind competitors like OpenAI and Google. LeCun believes world models could revolutionize AI by enabling machines to reason and plan like animals. His departure follows Meta's struggles with AI projects like Llama 4 and the AI chatbot, which have faced challenges and controversies.
