At the All In conference, a panel on world models highlighted the secrecy surrounding the field, with major players Yann LeCun’s AMI Labs and Fei-Fei Li’s World Labs ranking low on the trying-to-make-money scale despite buzz and funding. World models automate spatial intelligence, with potential in robotics, interactive video, and self-driving systems. Michael Rabbat, co-founder and VP of World Models at AMI Labs, was cagey when pressed on the company’s work, saying, “We’ll talk about it when we’re ready to talk about it,” and clarifying by email, “We’re still in a research and building phase, so we’re not talking publicly about any product plans or timeline.” AMI is less than a year old. World Labs’ Marble is probably the most fully developed product, with demos for media creation, explorable video game environments, and CGI effects, plus robotics use cases, but the platform seems designed to demonstrate capabilities. Secrecy extends to suppliers: Alex de Vigan, CEO of Physicl, a data supplier, said he knows his data has been useful but remains in the dark about what is being built, adding, “I wish they would tell us more. We could build more useful data if we knew what they were working on.” The mystery stems from world models’ versatility, from navigable maps like self-driving car models to humanoid robots or turning video into explorable
