World Labs develops Large World Models, AI systems capable of generating and rendering interactive three-dimensional environments in real time from diverse inputs. Its core product, Marble, utilizes a Real-Time Frame Model to create persistent, photorealistic virtual worlds that users can explore directly within a browser. This technology aims to streamline complex 3D content creation and simulation workflows by automating the generation of entire environments rather than isolated assets.
The company was founded in January 2024 by a team of distinguished AI researchers: Fei-Fei Li, Justin Johnson, Christoph Lassner, and Ben Mildenhall. Fei-Fei Li, renowned as the "Godmother of AI" and inventor of ImageNet, serves as CEO, driven by an insight that spatial intelligence is the next foundational challenge for artificial intelligence. Johnson contributed expertise in generative modeling, while Lassner's work on Pulsar and Mildenhall's co-creation of Neural Radiance Fields (NeRF) established critical advancements in 3D rendering and neural scene representation.
World Labs' technology serves a broad spectrum of industries, including AR/VR, content creation, gaming, visual effects, robotics simulation, and digital twin applications. The company envisions providing the foundational infrastructure for scalable 3D content production, empowering creators and developers to translate their creative intent directly into immersive 3D realities. This approach addresses the escalating demand for advanced 3D environments, supporting the evolution of interactive digital experiences.

World Labs is a spatial intelligence company building Large World Models (LWMs), frontier AI systems that perceive, generate, reason, and interact with 3D environments from text, images, videos, or 360 panoramas.[1][2] Its flagship product, Marble, launched in limited beta in September 2025, enables users to create persistent, photorealistic 3D worlds explorable in-browser with six degrees of freedom navigation, interactive editing, and exports in various 2D/3D formats.[1][2] World Labs serves creators in gaming, AR/VR, film/VFX, robotics simulation, architecture, and digital twins, solving the scalability bottleneck of manual 3D modeling by automating world-building for real-time, immersive content at unprecedented speed.[1][2]
The company addresses exploding demand for 3D content in AI-driven applications, where traditional workflows fail to keep pace, positioning Marble as foundational infrastructure for spatial AI use cases from storytelling to simulation.[1][2]
World Labs was founded in January 2024 by AI luminaries Fei-Fei Li (Co-Founder and CEO, pioneering computer vision expert known for ImageNet), Justin Johnson (Co-Founder, AI researcher), Christoph Lassner (Co-Founder, 3D modeling specialist), and Ben Mildenhall (Co-Founder, computer vision innovator).[1] The idea emerged from their expertise in vision and generation models, evolving from projects like "Marble" to tackle 3D environment generation with real-time simulation capabilities.[1]
Early traction built on this foundation, culminating in Marble's September 2025 beta launch, which introduced RTFM (Real-Time Frame Model) for browser-based exploration and generation, marking a pivotal shift from static assets to dynamic, explorable worlds.[1][2]
World Labs stands out in spatial AI through these key strengths:
These features deliver AI-native scalability, distinguishing World Labs from manual tools or narrower reconstruction models.[1]
World Labs rides the spatial intelligence wave, a next frontier in generative AI where models evolve from 2D pixels to interactive 3D worlds, fueled by AR/VR proliferation, robotics, and digital twins.[1][2][3] Timing is ideal amid surging demand for scalable 3D content—manual processes can't match AI speed—aligning with market forces like Cisco's investment signaling enterprise validation for human-like 3D interaction.[3]
By providing foundational infrastructure, World Labs influences the ecosystem, empowering gaming immersion, VFX efficiency, simulation accuracy, and immersive media, while accelerating AI's shift from perception to creation in physical-digital convergence.[1][2]
World Labs is poised to dominate spatial AI with LWMs, expanding Marble beyond beta to full production and new models for advanced reasoning and multi-agent simulation.[1][2] Trends like edge AI deployment, metaverse revival, and embodied robotics will propel growth, amplified by backers like Cisco enhancing network effects.[3]
As 3D becomes the default for AI agents and creators, World Labs' infrastructure could redefine content pipelines, evolving from world-builder to ecosystem orchestrator—transforming "seeing into doing" across industries.[2] This positions it as a cornerstone in the shift to truly interactive digital realities, building on its mission to make spatial intelligence ubiquitous.[1][2]
World Labs has raised $230.0M across 1 funding round. Most recently, it raised $230.0M Series U in September 2024.
