AMD has agreed to acquire Fei-Fei Li's World Labs for about $8.2 billion in stock, making it the chipmaker's second-largest acquisition and giving it a major foothold in "world models" that simulate 3D environments for robotics and other physically grounded AI. CNBC reports: AI researchers expect world models will be able to help develop robots and other physically-grounded artificial intelligence applications. AMD plans to keep World Labs separate from its chipmaking business until the transaction closes later this year. The lab's research on next-generation models will allow AMD to plan for what its AI chips need to be capable of years in advance. World Labs was founded by AI researcher Fei-Fei Li, who is widely seen as an AI pioneer as a Stanford professor, and who previously worked for Google leading AI research. Li will become an AMD's chief scientist and an executive vice president at the company. In a demo presented by Li and AMD CEO Lisa Su earlier this year, the two executives showed a World Labs model called Marble creating a three-dimensional scene out of a few images. "Intelligent agents, whether it's robots or vehicles or even tools, can learn inside very-rich physics-aware digital worlds before they even need to be deployed into the real one, making them much safer," Li said at the presentation.

Meta has hired MongoDB CEO Chirantan "CJ" Desai to lead a new enterprise AI business aimed at turning Meta's models, agents and tools into products companies can deploy themselves. Reuters reports: Desai, a veteran technology executive, took over the role from Dev Ittycheria. MongoDB has appointed Ittycheria as interim CEO as it searches for a permanent replacement. "While the departure is disappointing, we believe MongoDB remains well-positioned strategically and view the share-price reaction as overdone," brokerage Piper Sandler said in a note. [...] Desai will directly report to Meta CEO Mark Zuckerberg in the newly created role of chief enterprise platform officer and will focus on turning the company's AI stack into products and services that companies can deploy for their own businesses. Before joining MongoDB, Desai led product and engineering at Cloudflare and spent nearly eight years at ServiceNow, including as president and chief operating officer.
