Yann LeCun, Meta's pioneering Chief AI Scientist and Turing Award winner, left the company after over a decade to launch his own venture. In explosive interviews, he warned the tech industry that obsession with large language models (LLMs) represents a "dead end" for true superintelligence. His departure highlights deepening rifts over AI's future direction.
LeCun departed in November 2025 amid tensions with CEO Mark Zuckerberg, who lost faith in Meta's generative AI team after they allegedly "fudged" Llama 4 benchmarks in April 2025. He described a shift from open research freedom pre-ChatGPT to pressure for profitable products, sidelining his preferred "world models" that learn from video and spatial data. Despite personal goodwill with Zuckerberg, LeCun predicted mass exits from Meta's GenAI organization.
LeCun sharply criticized Meta's hire of 28-year-old Alexandr Wang from Scale AI, calling him "young and inexperienced" in research despite quick learning. He argued Wang's team is "completely LLM-pilled," ignoring broader AI paths like objective-driven systems that understand physics and plan hierarchically. LeCun emphasized researchers resist top-down directives, stating, "You certainly don't tell a researcher like me what to do."
LeCun urges the industry to abandon LLM hype, which he views as statistically clever but incapable of real-world reasoning without massive, inefficient scaling. His new startup, Advanced Machine Intelligence Labs (AMI Labs), targets $3 billion valuation by building world models for human-level AI. Meta will partner with AMI, signaling LeCun's influence endures.
LeCun's outspokenness challenges Big Tech's AGI race, echoing skeptics like Gary Marcus who back his non-LLM path but doubt quick success. As Meta invests billions in superintelligence via Wang, LeCun's exit could spur talent shifts toward diverse AI paradigms. Bitcoin markets, already volatile from Venezuela rumors, face indirect ripples if AI leadership instability erodes investor confidence in tech giants.
