World Labs is a spatial intelligence company founded by AI pioneer Fei-Fei Li, building frontier models that can perceive, generate, reason about and interact with the 3D world. The company frames spatial intelligence as the next step beyond language models, turning seeing into doing and imagining into creating, with applications spanning gaming, simulation, storytelling, design and eventually science.
Its first commercial product, Marble, generates persistent, interactive 3D worlds from text, image, video or panorama inputs. Rather than rendering scenes on the fly as a user explores, Marble produces downloadable, spatially consistent environments and includes AI-native editing tools, a hybrid 3D editor and a Chisel feature that decouples spatial structure from visual style. Generated worlds can be navigated, modified and exported into existing creative and game workflows.
World Labs emerged from stealth in 2024 with roughly 230 million dollars in funding and, per 2026 reporting, raised about 1 billion dollars to advance its world models, backed by investors including Nvidia, AMD, Fidelity, Autodesk, Emerson Collective and Sea. Led by one of the most influential figures in computer vision, the company is a closely watched contender in the race to build world models, serving 3D creators, game developers, designers and researchers who need to generate and work within virtual environments.
