Yann LeCun Raises $1 Billion for AI Startup to Challenge Silicon Valley's Chatbot Obsession

Advanced Machine Intelligence (AMI), a Paris-based startup cofounded by Meta's former chief AI scientist Yann LeCun, has raised more than $1 billion to develop AI world models. The financing values the startup at $3.5 billion and was co-led by investors including Cathay Innovation, Greycroft, Hiro Capital, HV Capital, and Bezos Expeditions. LeCun argues that most human reasoning is grounded in the physical world, not language, calling the idea that large language models will achieve human-level intelligence "complete nonsense." AMI aims to work with companies in manufacturing, biomedical, and robotics industries, potentially building realistic world models of systems like aircraft engines to optimize efficiency and reliability. AMI marks LeCun's first commercial venture since departing Meta in November 2025. The startup represents a contrarian bet against the LLM-dominated AI industry.
