AMD buys Fei-Fei Li's World Labs for $8.2 billion to challenge Nvidia in world models and physical AI

Ars Technica reports that AMD will acquire World Labs in a deal valued at $8.2 billion, expected to close by the end of the year pending regulatory approval. Fei-Fei Li founded World Labs in 2024 with Justin Johnson, Christoph Lassner and Ben Mildenhall, backed by $230 million in funding that included investment from AMD.

Li will become AMD's executive vice president and chief scientist, while Johnson and Mildenhall will continue to lead the World Labs team inside AMD. The structure suggests AMD is buying both research talent and a product line, and keeping the founding team in charge of the work it started. AMD's earlier investment in World Labs means the companies already had a relationship before the acquisition.

World Labs develops world models, AI systems that predict and simulate physical environments. Its Marble tool generates 3D spaces as exportable Gaussian splats for use in film and games, and later tools such as Atlas extended the lineup. A core part of the investment thesis is synthetic data for training robots, letting machines learn in simulated worlds before acting in real ones.

That is an area where Nvidia leads with its Cosmos platform and broader physical AI work, such as Skild AI teaching robots from a single video. Nvidia executives have argued that robots are waiting for a ChatGPT moment, and both chipmakers see simulation as a driver of compute demand.

The deal is part of a wave of large AI acquisitions by chipmakers. Nvidia agreed to buy Hugging Face for $12.9 billion earlier in September. For AMD, World Labs offers a software and research foothold in physical AI that could make its hardware more attractive to robotics and simulation customers.

Open questions include whether World Labs' public tools, such as Marble and Atlas, remain broadly available or become tied to AMD hardware, and whether regulators impose conditions given growing concentration in AI. AMD's roadmap language connecting World Labs to future silicon will indicate how central the acquisition is to its strategy. More in our robotics coverage and startups coverage.
