Yann LeCun Raises  Billion to Build AI That Understands the Physical World

Yann LeCun Raises $1 Billion to Build AI That Understands the Physical World

Advanced Machine Intelligence (AMI), a new Paris-based startup cofounded by Meta’s former chief AI scientist Yann LeCun, announced Monday it has raised more than $1 billion to develop AI world models.

LeCun argues that most human reasoning is grounded in the physical world, not language, and that AI world models are necessary to develop true human-level intelligence. “The idea that you’re going to extend the capabilities of LLMs [large language models] to the point that they’re going to have human-level intelligence is complete nonsense,” he said in an interview with WIRED.

The financing, which values the startup at $3.5 billion, was co-led by investors such as Cathay Innovation, Greycroft, Hiro Capital, HV Capital, and Bezos Expeditions. Other notable backers include Mark Cuban, former Google CEO Eric Schmidt, and French billionaire and telecommunications executive Xavier Niel.

AMI (pronounced like the French word for friend) aims to build “a new breed of AI systems that understand the world, have persistent memory, can reason and plan, and are controllable and safe,” the company says in a press release. The startup says it will be global from day one, with offices in Paris, Montreal, Singapore, and New York, where LeCun will continue working as a New York University professor in addition to leading the startup. AMI will be the first commercial endeavor for LeCun since his departure from Meta in November 2025.

LeCun’s startup represents a bet against many of the world’s biggest AI labs like OpenAI, Anthropic, and even his former workplace, Meta, which believe that scaling up LLMs will eventually deliver AI systems with human-level intelligence or even superintelligence. LLMs have powered viral products such as ChatGPT and Claude Code, but LeCun has been one of the AI industry’s most prominent researchers speaking out about the limitations of these AI models. LeCun is well known for being outspoken, but as a pioneer of modern AI that won a Turing award back in 2018, his skepticism carries weight.

LeCun says AMI aims to work with companies in manufacturing, biomedical, robotics, and other industries that have lots of data. For example, he says AMI could build a realistic world model of an aircraft engine and work with the manufacturer to help them optimize for efficiency, minimize emissions, or ensure reliability.

AMI was cofounded by LeCun and several leaders he worked with at Meta, including the company’s former director of research science, Michael Rabbat; former vice president of Europe, Laurent Solly; and former senior director of AI research, Pascale Fung. Other cofounders include Alexandre LeBrun, former CEO of the AI health care startup Nabla, who will serve as AMI’s CEO, and Saining Xie, a former Google DeepMind researcher who will be the startup’s chief science officer.

The Case for World Models

LeCun does not dismiss the overall utility of LLMs. Rather, in his view, these AI models are simply the tech industry’s latest promising trend, and their success has created a “kind of delusion” among the people who build them. “It’s true that [LLMs] are becoming really good at generating code, and it’s true that they are probably going to become even more useful in a wide area of applications where code generation can help,” says LeCun. “That’s a lot of applications, but it’s not going to lead to human-level intelligence at all.”

LeCun has been working on world models for years inside of Meta, where he founded the company’s Fundamental AI Research lab, FAIR. But he’s now convinced his research is best done outside the social media giant. He says it’s become clear to him that the strongest applications of world models will be selling them to other enterprises, which doesn’t fit neatly into Meta’s core consumer business.

As AI world models like Meta’s Joint-Embedding Predictive Architecture (JEPA) became more sophisticated, “there was a reorientation of Meta’s strategy where it had to basically catch up with the industry on LLMs and kind of do the same thing that other LLM companies are doing, which is not my interest,” says LeCun. “So sometime in November, I went to see Mark Zuckerberg and told him. He’s always been very supportive of [world model research], but I told him I can do this faster, cheaper, and better outside of Meta. I can share the cost of development with other companies … His answer was, OK, we can work together.”

For some social media users, Facebook may feel like an app left behind in an online era of the past. However, for others, Facebook has reinvented itself as the modern-day Craigslist with Facebook Marketplace.

Meta seems to have taken notice and is now releasing a standalone app for the Facebook Marketplace power users who keep the platform going: It’s sellers.

The new app, aptly named Seller, launched on Friday and provides Facebook Marketplace sellers with tools to list their wares and manage their current listings. 

Like Facebook Marketplace itself, the Seller app is free for users. Meta monetizes Facebook Marketplace with ads and does not take any percentage of its users’ sales. Users will be able to download the app and login with their Facebook account starting today.

Seller provides a tool to post new listings, a dashboard to manage their existing ones, an in-app inbox to reply to prospective buyers, and analytics for all of their old listings. Seller also introduces a few new tools for sellers as well. According to Facebook, Seller users will be able to scan their products with their smartphone, and AI will fill-out the listing details automatically.In an interview with the New York Times, Facebook head Tom Allison said that the app would be the Marketplace seller equivalent of a video editing tool for content creators. Allison also explained how Meta is experimenting with more standalone products for Facebook’s power users, which include Marketplace Sellers and Facebook Groups administrators.
As social media users move to competing platforms like TikTok and Meta’s own Instagram, Facebook has found new life within specific, once-niche features on the platform. In May, Facebook launched a standalone app called Forum for its Facebook Groups power users. Now, the company is doing the same for Facebook Marketplace sellers.Meta says that one-third of young adults who use Facebook also use Marketplace. And, every month, more than 420 million items are listed on the Marketplace platform.
