Yann LeCun Leaves Meta for World Models
13 Nov 2025- Yann LeCun plans to leave Meta to launch a startup building video/spatial world models, fundraising underway, amid Meta’s AI reorganization and internal tensions over technical direction.
13 Nov 2025
Longtime Meta Chief AI Scientist and Turing Award winner Yann LeCun is reportedly planning to leave Meta in the coming months to launch a startup focused on “world models,” with fundraising talks already underway. According to the Financial Times (as reported by The Rundown), LeCun intends to build models that learn from video and spatial data rather than the text-centric systems dominating much of the current AI landscape. LeCun has led Meta’s FAIR research arm since 2013 and recently began reporting to Alexandr Wang following Meta’s major AI reorganization.
The move follows a summer of internal friction: Meta has restructured its AI teams and cut roughly 600 positions across its AI divisions (excluding the new TBD Lab overseen by Wang). LeCun’s departure would turn an internal debate over technical direction into a public test between competing visions for AI — spatial/video-based world models versus the prevailing text-based approaches. The story frames his exit as both unsurprising given ongoing tensions and consequential, since it will pit a high-profile researcher’s independent effort directly against Meta’s newly prioritized strategy.
