# World Labs

> World Labs builds AI models that generate and reconstruct navigable 3D environments. Its Marble application, World API and open-source Spark renderer serve creators and developers, while Atlas and its SceniX robotics work extend the research toward simulation. In September 2026, AMD agreed to acquire the San Francisco company in an approximately $8.2 billion all-stock transaction, expected to close by year-end.

- **Founded:** 2024
- **Headquarters:** San Francisco, United States
- **Founders:** Fei-Fei Li (Co-founder and CEO), Justin Johnson (Co-founder), Christoph Lassner (Co-founder), Ben Mildenhall (Co-founder)
- **Products:** Marble, Chisel, World API, Spark, Atlas
- **Notable:** Launched Marble publicly on November 12, 2025., Released World API on January 21, 2026., Announced $1 billion in new funding in February 2026, bringing announced financing to $1.23 billion.

## Products & services

- **Marble** — Browser application for creating, editing, expanding and exporting persistent 3D worlds from multimodal inputs.
- **Chisel** — Experimental Marble editing mode that uses coarse 3D layouts to control scene structure separately from visual style.
- **World API** — Public asynchronous world-generation API for embedding Marble capabilities in software.
- **Spark** — Open-source MIT-licensed Gaussian splat renderer for Three.js; version 2.0 adds streaming and level-of-detail management.
- **Atlas** — Multimodal model for generation, reconstruction and simulation; announced September 2026 in early access with select partners.
- **RTFM** — Research preview of interactive real-time video world generation.
- **Real-to-sim-to-real engine** — SceniX-derived technology for reconstructing robotic tasks, varying simulations and evaluating policies against real-world outcomes.
