Marble (World Labs)

Marble, World Labs' first product, is a multimodal world model that generates persistent, editable, downloadable 3D worlds from text, images, video, panoramas, or coarse 3D, viewable in VR.

Marble generates high-fidelity 3D worlds from multiple input types, including natural-language descriptions, single or multiple images, panoramas, short videos, and rough 3D structures. Unlike single-view image-to-3D tools, it aims for persistent, coherent environments you can move through, edit, and export, backed by World Labs' research into large-scale world models. Every world can be viewed in VR, and the outputs are downloadable for use in other pipelines. As a debut product from a heavily funded lab, Marble is early but ambitious, positioning itself for uses from creative worldbuilding and game prototyping to robotics and embodied-AI training. It launched as a freemium platform with several subscription tiers, from a free entry point to a higher-priced plan with commercial rights. The category is nascent, so expectations should be calibrated: it is a frontier tool showing what generative world models can do, not yet a mature production pipeline.
