🟣 Fei-Fei Li’s World Labs Launches Marble 3D World Model — The First Commercial 3D World Model

World Labs logo featured in NewBits Digest article on the Marble 3D world model and next-generation spatial intelligence.

AI legend Fei-Fei Li — co-creator of ImageNet, a pioneer of modern computer vision, and co-director of Stanford’s Human-Centered AI Institute — has a new company, World Labs, which just released Marble, a groundbreaking 3D world model that turns text, images, video, or 3D layouts into persistent 3D environments, leapfrogging rivals like Google’s Genie. The Marble 3D world model is designed to move AI beyond flat text into fully interactive spatial environments.


📌 Key Points About the Marble 3D World Model


  • 🌍 Generate brand-new 3D worlds using text, images, videos, or layout sketches.


  • 🎛️ Edit, combine, expand, or make pixel-level changes to existing environments.


  • 🧱 Export as Gaussian splats, meshes, or video, ready for games, VFX, VR, robotics, architecture, and more.


  • 💳 Now broadly available with freemium + paid tiers starting at $20/mo.


  • 🧠 Launch aligns with Fei-Fei Li’s essay arguing that spatial intelligence models will define the next era of AI beyond text-only LLMs.


⭐ Why It’s Important


World models unlock the ability for AI to understand, simulate, and inhabit space — a massive leap beyond language-only intelligence.

Marble will quickly become part of workflows across gaming, robotics, film, education, architecture, simulation, and world-building, enabling creators to generate entire universes with a prompt.
