Yann LeCun, one of the 'godfathers of AI' and Meta's Chief AI Scientist, is departing the company to create a startup focused on Advanced Machine Intelligence (AMI) and world models. His exit follows internal tensions over AI direction and resource allocation at Meta.

The Departure of an AI Pioneer

Yann LeCun, one of the most influential figures in artificial intelligence and Meta's Chief AI Scientist for over a decade, announced his departure from the company to launch an independent AI research startup

LeCun's announcement comes just weeks after receiving recognition from King Charles for his contributions to artificial intelligence, highlighting his continued prominence in the field

. His departure marks the end of a significant era at Meta, where he founded and led the Fundamental AI Research (FAIR) laboratory since joining the company in 2013.

Vision for Advanced Machine Intelligence

The new startup will focus on what LeCun calls Advanced Machine Intelligence (AMI), representing his vision for the next generation of AI systems. "The goal of the startup is to bring about the next big revolution in AI: systems that understand the physical world, have persistent memory, can reason, and can plan complex action sequences," LeCun wrote in his announcement

This approach diverges significantly from the current industry focus on large language models (LLMs). LeCun has been openly critical of the prevailing wisdom that scaling LLMs will lead to human-level AI, stating during a podcast appearance that "we are not going to get to human-level AI by just scaling LLMs"

. His research centers on "world models" - AI systems trained on visual data from the physical world rather than text, designed to understand cause and effect in real-world interactions

Internal Tensions at Meta

LeCun's departure occurs amid significant upheaval within Meta's AI division. The company has undergone dramatic restructuring following lukewarm reception of its Llama 4 model, prompting CEO Mark Zuckerberg to invest heavily in new AI talent

. This included a $14.5 billion investment in Scale AI to recruit 28-year-old CEO Alexandr Wang as Meta's new Chief AI Officer, and hiring ChatGPT co-creator Shengjia Zhao as Chief AI Scientist of the newly formed Meta Superintelligence Labs

Reports suggest LeCun faced challenges securing resources for his projects as Meta shifted focus toward competing directly with OpenAI, Google, and Anthropic

. The company also cut "several hundred" jobs from its Superintelligence group, including positions within FAIR, further indicating the organizational changes affecting LeCun's work

Partnership and Future Collaboration

Despite his departure, LeCun's new startup will maintain a partnership with Meta, though specific details remain undisclosed

. LeCun emphasized that while some research applications will overlap with Meta's commercial interests, many will not, making an independent entity the optimal approach to "maximize broad impact"

.

This arrangement reflects broader trends in AI industry partnerships, where tech giants maintain strategic relationships with key researchers and startups. LeCun will continue his professorial role at New York University, where he has taught since 2003, allowing him to maintain academic connections while pursuing commercial applications of his research
