World Labs

World Labs is a leading spatial intelligence company, building frontier world models that can perceive, generate, reason, and interact with the 3D world.

World Labs was founded by visionary AI pioneer Fei-Fei Li along with Justin Johnson, Christoph Lassner, and Ben Mildenhall, each a world-renowned technologist in machine learning, generative AI, computer vision, and graphics. It brings together a world-class team, united by a shared curiosity, passion, and deep backgrounds in technology — from AI research to systems engineering to product design — creating a tight feedback loop between our cutting-edge research and products that empower our users. Its first product, Marble, is powered by best-in-class generative 3D world models and enables anyone to create spatially cohesive, high-fidelity, and persistent 3D worlds from just a single image, video or text prompt.
