Atlas opens to everyone: generate a 3D world from one image, export video and Gaussian splats

On November 12, Fei-Fei Li announced on X that World Labs' Atlas is open to everyone. World Labs calls Atlas its latest world model.

Atlas's outputs are very concrete: keyframes, video clips, and 3D Gaussian splats. 3D Gaussian splats are a way of representing a 3D scene with Gaussian point clouds that can be rendered from new viewpoints. For developers, the API endpoints carry more weight than demo videos.

World Labs has also opened three entry points. Viewfinder turns images into worlds: a single image generates a complete world, and up to 64 inputs can reconstruct a real environment, exporting spatially consistent images, videos, or splats.

Chisel focuses on explicit 3D geometry around agentic workflows: text prompts or reference images go in, a 3D world comes out, then it renders images/video or exports splats, with the ability to change visual style.

All API endpoints are released, and developers and agents can call them directly. Build your own tools, or let agents interact with the model.

The sign-up entry point is atlas.worldlabs.ai. Some users posted the registration prompt "Please fill in the remaining details" and replied "NO." Another user asked whether splats in VR have higher resolution than conventional methods; this question has no answer yet.

Only when a world model can export assets and plug into existing pipelines does it turn from a demo into a tool. Atlas provides the API and export formats together, and the direction is clear. The entry point is open; what remains is to see what users do with it.
