World Labs opens Atlas world model to the public with developer API

World Labs announced on November 12, 2026 that Atlas, its world model pretrained natively on text, images, video and 3D, is now open to the public through web tools and a developer API. The news came in a post titled Atlas: Releasing our next generation world model, which expands on the research preview the company first shared on September 1, 2026.

What changed in this release

• Atlas is pretrained from scratch to operate natively on text, images, video and 3D, built as a multimodal autoregressive diffusion transformer that uses shared spatial context.
• The model can now be tried through web apps and through developer API endpoints at atlas.worldlabs.ai/developers.
• Outputs can be saved as 3D Gaussian Splatting scenes or exported as meshes for use in Blender and other game engines.
• Developers can render splats directly on the web with sparkjs.dev, one of the tools World Labs lists alongside the API.
• World Labs has not disclosed pricing for Atlas on the announcement page.

What it means for people building with AI

A public API turns Atlas from a limited early access tool into a product that developers and creative AI builders can call programmatically for scene reconstruction and game asset pipelines. That shift matters for teams that want to generate usable 3D scenes or splats without waiting for manual access, since the model now has a defined API surface to build around.

Availability and pricing

Company co-founder Fei-Fei Li said on X the same week that Atlas is now available to everyone. World Labs has not published pricing for the API or web apps, so builders who want to use Atlas will need to check the developer page for current terms.
