Yann LeCun Leaves Meta to Build AMI Labs on ‘World Models,’ Says LLMs Are a Dead End

He labels large language models a dead end following a leadership shake-up at Meta.

Overview

  • The former chief AI scientist argues advanced intelligence requires systems that learn predictive world models from video and spatial data rather than relying on language alone.
  • He departed in November after being reassigned to report to Alexandr Wang, who joined through Meta’s $14.3 billion Scale AI deal to help lead Meta Superintelligence Labs.
  • He criticized Wang as young and inexperienced and said researchers of his stature should not be directed on what to study.
  • He tied Llama 4’s weak reception to internal pressure for rapid progress and alleged that some benchmark results were manipulated, a claim not independently verified in the articles.
  • He has launched Advanced Machine Intelligence Labs and is seeking funding, with reports indicating a target valuation of about $3 billion.
