What does World Labs do?

World Labs is a spatial intelligence company based in Stanford, California, founded in 2024. It specializes in generative AI through Large World Models (LWMs), which allow AI systems to perceive and interact with 3D environments using various inputs like text, images, and videos. Co-founded by AI researcher Fei-Fei Li, World Labs aims to redefine how AI understands 3D spaces, creating immersive virtual worlds for applications in storytelling and simulation. The company's flagship product, Marble, launched in limited beta in September 2025, generates high-fidelity, photorealistic 3D worlds that can be explored in-browser. Key features include multimodal world creation, interactive editing, and the ability to expand and combine worlds. Marble supports industries such as gaming, AR/VR, film, robotics, and manufacturing, providing tools for advanced 3D simulation and content creation. World Labs also offers resources like case studies and tutorials to assist users in leveraging their technology effectively.
