Marble is available on a freemium model. The free tier provides access to core world generation features with a limited credit allocation for experimentation. Paid plans unlock higher-volume generation and additional capabilities. Specific plan pricing and credit details are listed on the official Marble website.
Quick Summary
Marble is a multimodal world model developed by World Labs, the spatial intelligence startup founded by Stanford AI researcher Fei-Fei Li, that generates persistent, navigable, and exportable 3D environments from text prompts, single or multiple images, videos, 360-degree panoramas, or coarse 3D layouts. It is designed for game developers, VFX artists, architects, robotics researchers, and interactive content creators who need to produce complete 3D scenes without manual modeling. Marble became generally available in November 2025 and is the first commercial product from World Labs, which raised $230 million in funding before launch.
