World Labs
AI pioneer Fei-Fei Li's spatial-intelligence startup, building world models that generate navigable 3D environments from images, video or text. World Labs raised $1 billion in February 2026 (bringing total funding to $1.23 billion) with Autodesk investing $200 million alongside Andreessen Horowitz, NVIDIA and AMD, and launched its first product, Marble, which creates exportable 3D meshes and video from simple prompts, targeting storytelling, creativity, robotics and scientific-discovery applications.

World Labs's Timeline
A sourced, dated history of World Labs's key moments — founding to present.
Jan 2024 · Founded
World Labs was founded by Fei-Fei Li to build world models advancing spatial intelligence.
Jan 2026 · Launches RTFM real-time generative world engine
World Labs introduced RTFM (Real-Time Frame Model), a system capable of generating and rendering video in real time as users explore virtual spaces, powered by an H100; unlike Marble, which creates persistent, downloadable 3D environments, RTFM generates worlds on-the-fly as users move through them, and Marble Studio added a new Level-of-Detail splat-rendering backend supporting significantly larger, editable composed worlds.
Feb 2026 · Raises $1B, launches Marble
World Labs raised $1 billion (total funding $1.23 billion) with Autodesk contributing $200 million alongside Andreessen Horowitz, NVIDIA and AMD, and launched Marble, its first product for generating 3D worlds from images, video or text.
