Yann LeCun’s new startup just closed Europe’s largest-ever seed round — $1.03 billion — to build AI world models as an alternative to large language models.
Yann LeCun has a problem with large language models. And now he has $1 billion to do something about it.
Advanced Machine Intelligence Labs — AMI Labs — the Paris-headquartered startup co-founded by LeCun, the former Meta chief AI scientist and Turing Award winner, has closed a $1.03 billion seed round at a $3.5 billion valuation. It is Europe’s largest seed round on record, and one of the largest anywhere. The company is less than six months old.
“We just completed our seed round, one of the largest seeds ever, probably the largest for a European company,” LeCun said in announcing the raise.

A Different Bet on What AI Should Be
The core premise of AMI Labs directly challenges the architecture that currently dominates the AI industry. Rather than building large language models — the approach that underpins OpenAI, Anthropic, Google, and xAI — the company is developing what it calls AI world models: systems designed to understand physical reality by predicting how the world actually behaves.
Where LLMs consume vast quantities of text data and generate outputs based on patterns in that data, world models attempt to construct an internal representation of how things work — cause and effect, physical consequence, the underlying logic of the real world rather than statistical patterns in language.
It is an approach that LeCun has been publicly arguing for years. Now he has institutional backing to build it.
Who’s Writing the Checks
The round was co-led by Paris-based Cathay Innovation alongside Greycroft, Hiro Capital, and HV Capital, with participation from Jeff Bezos’ Bezos Expeditions. Former Google chief executive Eric Schmidt and web inventor Tim Berners-Lee are also among the backers. NVIDIA and Samsung have joined the round as strategic investors — a signal that the hardware and device ecosystems are watching the world model approach closely.
Alexandre LeBrun, former chief executive of French health AI startup Nabla, is serving as CEO. LeCun, who departed Meta last year, takes the role of executive chair.

The Geography of the Bet
The size and composition of the round carry a significance beyond the technology itself. A $1 billion seed — raised in Europe, for a company building an explicit alternative to Silicon Valley’s dominant AI paradigm — is a statement about where the next chapter of AI competition might be written. AMI Labs is building teams in Paris, New York, Montreal, and Singapore, a footprint that reflects both its international ambitions and its deliberate distance from the Bay Area’s center of gravity.
Whether world models can deliver on the promise LeCun has long attached to them remains the open question. LLMs, for all their limitations, have proven stubbornly capable and commercially entrenched. Displacing that consensus will take more than a compelling theory and a well-capitalized team — though AMI Labs is arriving with both.
