Yann LeCun, one of the most influential figures in artificial intelligence and a pioneer often referred to as a “godfather of AI,” has announced he will step down from Meta at the end of the year to launch a new machine learning company. The move marks the end of a 12-year tenure during which he played a central role in shaping Meta’s AI research efforts.
In a message posted on LinkedIn on Wednesday, LeCun said his departure follows five years as the founding director of Meta’s AI research lab, FAIR, and seven years as the company’s chief AI scientist. He said the time had come to pursue an independent path focused on advancing research he believes will drive the next major leap in artificial intelligence.
LeCun has been increasingly outspoken about what he sees as the limitations of large language models, the technology behind systems such as ChatGPT and Meta’s Llama. Despite Meta investing billions of dollars in LLM development, he has argued that these models will not lead to true machine intelligence.
“LLMs are great, they’re useful, we should invest in them — a lot of people are going to use them,” he said during an event on Sunday. “They are not a path to human-level intelligence. They’re just not.” He added that the dominance of LLM-focused research had drained resources from exploring alternative approaches, which he considers essential for long-term progress.
LeCun has long advocated for “world models,” a different form of AI that learns using visual data such as videos. Unlike language models that predict the next word in a sequence, world models attempt to predict what happens next in a physical environment, allowing systems to develop an understanding of cause-and-effect. He views this approach as key to building machines capable of reasoning, planning, and interacting more naturally with the real world.
His new company will focus on developing the Advanced Machine Intelligence (AMI) program he had been working on at FAIR and New York University. LeCun said the goal is to create systems that can understand the physical world, maintain persistent memory, and plan complex actions. The start-up, called AMI — also the French word for “friend” — will pursue applications across multiple industries.
While the company’s work may intersect with Meta’s interests in some areas, LeCun noted that many applications will fall outside Meta’s commercial scope. He said launching AMI as an independent venture would allow the research to have wider impact. He also expressed appreciation to Meta CEO Mark Zuckerberg, adding that Meta will serve as a partner in the new venture, though he did not detail the specifics of that partnership.
