Overview

World Labs' first commercial product and, in its own words, a frontier multimodal world model. Text prompts, photos, videos, panoramas or coarse 3D layouts become persistent, editable 3D environments that export as Gaussian splats, meshes or video. The distinction from frame-by-frame world generators is that the scene geometry is fixed once generated: a world can be revisited, edited and walked through again instead of being re-dreamed on every move. Available to everyone from launch in free and paid tiers; Marble 1.1 later added auto-expanding worlds, and the World API followed in January 2026.

Benchmarks

No established, comparable metric exists for world models yet. A video model goes from prompt to clip; a world model goes from an image or scene to a navigable space with camera control, which no video or image board measures. No scores and no crown until one exists.
