Why Yann LeCun left Meta, and what it means for AI's next frontier

"When one of the founders of modern AI walks away from one of the world's most powerful tech companies to start something new, the industry should pay attention. Yann LeCun's departure from Meta after more than a decade shaping its AI research is not just another leadership change. It highlights a deep intellectual rift about the future of artificial intelligence: whether we should continue scaling large language models (LLMs) or pursue systems that understand the world, not merely echo it."

"LeCun is a French American computer scientist widely acknowledged as one of the "Godfathers of AI." Alongside Geoffrey Hinton and Yoshua Bengio, he received the 2018 Association for Computing Machinery's A.M. Turing Award for foundational work in deep learning. He joined Meta (then Facebook) in 2013 to build its AI research organization, eventually known as FAIR (Facebook/META Artificial Intelligence Research), a lab that tried to advance foundational tools such as PyTorch and contributed to early versions of Llama."

"Over the years, LeCun became a global figure in AI research, frequently arguing that current generative models, powerful as they are, do not constitute true intelligence. LeCun's decision to depart, confirmed in late 2025, was shaped by both strategic and philosophical differences with Meta's evolving AI focus."
