Meta’s AI Chef Yann LeCun Cooks Up New Brainy Mess

KEY POINTS

•Yann LeCun announced on Facebook that he is leaving Meta to start his own AI company focused on world-model research.
•Meta confirmed the departure and said it will continue collaborating with LeCun on his new venture without revealing details.
•The exit follows Meta’s big AI reorganization under Alexandr Wang and growing tensions between new hires and existing researchers.
•Meta’s recent Llama 4 release had muted reactions, and PyTorch founder Soumith Chintala left Meta for Thinking Machines Lab.

Yann LeCun, the big cheese of Meta AI and self-declared AI renaissance man, is ghosting his Facebook overlord to birth a new AI startup obsessed with ‘world-model research’—code for thinking AI should watch the world, not just chat its guts out. His exit ships amid Meta’s latest AI cluster shuffle headed by Alexandr Wang, ex-Scale CEO, who’s apparently playing musical chairs with top AI talent so hard some threatened to quit. Meanwhile, Meta's Llama 4 drop performed at a ‘meh’ level, Soumith Chintala (PyTorch founder) jumped ship to Thinking Machines Lab, and LeCun’s anti-LLM stance spells ‘gone fishing’ from Meta’s cash-frenzied scale-up party.
