World Labs co-founder Fei-Fei Li shows off Marble

Dr. Fei-Fei Li, co-founder and CEO of World Labs and arguably one of the most influential researchers in AI, was another guest during AMD chair and CEO Lisa Su’s keynote during CES.

The conversation touched on all the promises of AI, especially when it comes to creating worlds. Li showed off the capability of her company’s first product Marble, which uses generative 3D world models to bring spatial intelligence to life. World Labs is backed by AMD’s venture arm.

Li demonstrated how Marble was able to quickly create a 3D world that still obeys the laws of physics. Marble can be used to create imaginary worlds or using photos of, say, Vegas to re-create it in a digital 3D model.

“What you don’t see here behind the scene is how much computation and why inference speed really matters,” Li said. The faster we can run these models, the more responsive the world becomes. Instant camera moves, instant edits, and a scene that stays coherent as you actually navigate and explore and that’s what’s really important.”
