World Labs opens Atlas world model and API to everyone

World Labs has opened Atlas, its world model, to everyone, with apps and API endpoints that return keyframes, video clips or 3D Gaussian splats (announcement). Atlas was introduced in September behind an early-access request. According to the company's Atlas post, it takes one or more reference images and generates new views of the scene from any camera position and angle the user specifies, filling in parts the inputs never showed, and it can reconstruct a real place from a handful of photos. Giving it more images means it imagines less and reconstructs more.

The three output types matter because they lead to different uses. Images and video come straight from the camera-controlled generation. A Gaussian splat is a 3D scene representation that World Labs' earlier model, Marble, produced for every request. In an a16z interview, the company explained that splats render efficiently on phones and VR headsets and can be brought into game and simulation engines, but forcing every output through them had been a bottleneck. Atlas was redesigned around predicting new views, and splats are generated from those views only when a 3D asset is actually needed. The Atlas product page lists the launch tools: Viewfinder for rebuilding a scene from photos and rendering camera paths, Chisel for blocking out a scene, converters from splats to meshes for games, relighting, and integrations including Blender.

The announcement itself does not say what open access costs or what usage limits apply, and its demo video was not transcribed, so output quality and pricing are not covered here. What has changed is that a model previously reached through a waitlist can now be called from developers' own software, with a choice between flat video and an exportable 3D world.
