There's a particular kind of audacity required to walk away from one of the world's premier AI research labs, declare you're starting fresh, and then—within months—announce you've raised more than a billion dollars. Before shipping anything. Before, really, proving much of anything at all.
Yann LeCun did exactly that. On March 10, the veteran AI researcher disclosed that Advanced Machine Intelligence—AMI Labs, for short—had closed a $1.03 billion seed round. The financing, among the largest ever at that stage in Europe, values the Paris-based startup at $3.5 billion before the money even hits the bank. It's the kind of number that used to be reserved for companies with revenue, customers, maybe even profits. Now? Ten employees and a vision apparently suffice.
The cast of backers is impressive, bordering on improbable. Cathay Innovation, Greycroft, Hiro Capital, HV Capital, and Bezos Expeditions co-led. Then came the parade: NVIDIA, Samsung, Toyota Ventures, Temasek. Eric Schmidt wrote a check. So did Mark Cuban, Jim Breyer, and Tim Berners-Lee. It's the sort of investor syndicate that seed-stage founders hallucinate about, the kind that usually emerges only when someone with LeCun's résumé comes calling.
Leaving Meta, Taking a Bet
LeCun publicly announced on November 19 that he would leave Meta at the end of 2025, a quiet end to a tenure that reshaped how the company—and much of the industry—thinks about AI. He'd founded Facebook AI Research back in 2013, building it into what became one of the field's most influential labs. The timing of his exit, though, raised eyebrows. Meta had just committed $14.3 billion to Scale AI, including the recruitment of its CEO, Alexandr Wang, to spearhead a new superintelligence initiative. A shift in strategic priorities, perhaps. Or maybe just a signal that LeCun's vision no longer aligned neatly with Meta's roadmap.
In interviews with Le Monde and the Associated Press, LeCun framed the move as intellectual restlessness, not corporate disaffection. He's after something specific: AI systems that "understand the physical world, have persistent memory, can reason, and can plan complex action sequences." Meta, he noted, would remain a collaborator—just not an investor.
That distinction isn't trivial. LeCun is 65, old enough to have earned his Turing Award already (shared in 2018 with Geoffrey Hinton and Yoshua Bengio for foundational work on neural networks). His contributions to computer vision date back to AT&T Bell Labs in the late '80s and early '90s, when convolutional neural networks were still exotic. He's spent years arguing, sometimes testily, that the industry's obsession with scaling language models is missing the point. The next breakthrough, he believes, won't come from bigger transformers. It'll come from machines that learn how the world actually works.
What "World Models" Actually Mean

AMI's technical thesis revolves around what LeCun calls world models—a framework he detailed in a 2022 position paper titled "A Path Towards Autonomous Machine Intelligence." The core idea: train AI systems to predict future states of the world not pixel-by-pixel, but in abstract representation space. It's built around something called Joint Embedding Predictive Architecture, or JEPA, which sounds arcane until you consider what it's trying to do. Rather than brute-forcing predictions from raw data, the system learns compressed, high-level representations of how things move, change, and interact.
Weeks after the funding announcement, researchers published a paper on arXiv describing LeWorldModel as "the first JEPA that trains stably end-to-end from raw pixels." Coincidence? Unlikely. AMI appears to be moving quickly—perhaps more quickly than typical academic timelines would suggest—from theoretical frameworks to working implementations.
CEO Alexandre LeBrun, who previously sold Wit.ai to Facebook in 2015 and later co-founded healthcare AI startup Nabla, told TechCrunch that AMI intends to "publish papers and make a lot of code open source." That tracks with LeCun's long-standing commitment to open research, though it leaves the commercial model somewhat nebulous. Le Monde reported the company is exploring dual paths: a paid API and a downloadable version for on-premises deployment. Classic enterprise hedging.
A Global Lab, a Narrow Team
From the start, AMI planted flags in Paris, New York, Montreal, and Singapore. Laurent Solly, Meta's former VP for Europe, signed on as COO. Saining Xie took the role of Chief Scientific Officer; Pascale Fung became Director of Research & Innovation; Michael Rabbat leads world models as VP. It's a geographically distributed operation, which makes sense for an AI lab trying to recruit top-tier talent in a brutally competitive market.
According to Le Monde, the company had around 10 employees at launch, with plans to scale to 30-50 within six months. For a billion-dollar seed round, that's... lean. But perhaps appropriate. Early-stage AI research isn't a headcount game. The first dozen hires will set the technical direction, define the culture, establish the pace. Better to move slowly there than flood the org chart prematurely.
LeBrun named Nabla—the digital health startup he co-founded—as AMI's first partner, which has a certain circularity to it. The company has also signaled interest in collaborations with Toyota and Samsung, both of which participated in the funding. Target sectors include industrial automation, robotics, healthcare, and wearable devices. Broad strokes, but the connective tissue is clear: anywhere machines need to operate in the physical world.
The Crowded Frontier

AMI isn't pioneering this space alone. Fei-Fei Li's World Labs reportedly raised $1 billion in February, valuing the company north of $4 billion, to pursue what it calls "spatial intelligence." LeBrun predicted to TechCrunch that "world models" would become the next buzzy term in AI—the successor to "transformers" or "large language models." If he's right, that means the category is about to get very crowded, very fast.
The real question is execution. LeCun told Wired he expects to release initial models quickly, though with limited public visibility at first, working toward what he termed a "universal world model." That's a multi-year horizon. Maybe longer. Yet investors committed over a billion dollars at seed stage, betting not on traction or revenue or even a finished prototype, but on the strength of LeCun's track record and the coherence of his technical vision.
The funding buys time—years of it, probably—to pursue that vision without the immediate pressure to monetize or justify quarterly metrics. Whether it produces the kind of paradigm shift LeCun has been advocating for remains an open question. For now, though, he's assembled the capital, the team, and the mandate. What comes next is the hard part.
