Li Feifei's Atlas is now fully open, enabling generation of 3D worlds from photos, as well as model export and API access.

Beating AI News: World Labs, founded by Fei-Fei Li, announced that its world model Atlas is now fully open to all users. Previously, Atlas was only available to invited testers; now regular users can create and edit virtual worlds via web tools, while developers can integrate the model through its API. The Viewfinder tool lets users upload one or more images, prompting Atlas to fill in the space outside the uploaded visuals, then freely adjust camera positions to generate perspective-specific images and videos. Another tool, Chisel, allows users to build simple 3D scenes, adjust room layouts and object positions, and have AI generate visuals based on those structures. Generated outputs can be saved as 3D Gaussian Splatting scenes, further converted to 3D mesh models with actual geometric structures, and imported into software like Blender and game engines for further use. World Labs has also opened related APIs, enabling developers to integrate scene generation, video production, and 3D reconstruction capabilities into their own products. Atlas launched in September this year, and last week the company rolled out Frameboy, a tool for real-time exploration of virtual worlds. At that time, the public version only allowed users to experience pre-made official scenes; creating custom scenes still required applying for Viewfinder test access. Now Viewfinder is also officially open: users can upload their own assets to build virtual worlds, then explore them in real time via Frameboy.
