Marble by World Labs – Founded by AI visionary Fei-Fei Li, World Labs introduces Marble, a breakthrough multimodal world model that generates persistent, editable 3D environments from text prompts, images, videos, or layouts. As the first commercial product from the $230M-funded startup, Marble advances spatial intelligence—enabling creators to build immersive, navigable worlds for gaming, VFX, design, robotics, and more.
What Is Marble by World Labs?
Marble is a frontier multimodal world model from World Labs that creates high-fidelity, persistent 3D worlds. Unlike video generators with inconsistencies, Marble produces stable, explorable environments exportable as Gaussian splats, meshes, or videos.
For beginners, Marble is intuitive: Visit marble.worldlabs.ai, enter a text prompt or upload an image/video, and generate a walkable 3D scene in minutes—no expertise required.
Intermediate users combine inputs (multi-images, videos) for richer reconstructions or use Chisel for hybrid editing.
Advanced creators leverage AI-native tools to expand scenes, edit styles, or integrate into pipelines like Unreal Engine.
Marble supports diverse styles (photorealistic to anime) and is available via freemium tiers.
The Evolution of Marble
World Labs emerged in 2024 with a focus on Large World Models (LWMs) for spatial intelligence.
Previews in September 2025 showcased single-image 3D generation.
Full launch in November 2025 introduced commercial access, editing tools, and Marble Labs hub.
As of January 2026, Marble continues refinements in fidelity, expansion, and exports, with community-driven case studies.
This trajectory positions Marble as a foundational tool for the spatial AI era.
