Marble

Marble is a groundbreaking large spatial generation model from World Labs, the team co-founded by Dr. Fei-Fei Li, the "godmother of AI." It pushes the boundary of generative AI from 2D pixels firmly into 3D physical space: with a simple text or image input, users can instantly build immersive virtual worlds with real geometric structure and depth, delivering an unprecedented three-dimensional imagination loop for creators.

Core Capabilities

• Multimodal scene generation: Accepts natural language text descriptions, a single image, a 360° panorama, or a short video as prompt input, generating persistent, freely explorable 3D virtual spaces within minutes.
• Chisel deep layout editing: Provides a powerful built-in 3D whitebox building editor. Creators use basic geometric shapes to precisely control a scene's spatial layout, then hand it to the AI for high-quality style rendering and material filling.
• Highly stable physical space experience: It thoroughly solves the physical collapse problem of traditional AI video generation during viewpoint movement — Marble's scenes have strict geometric consistency and support realistic first-person roaming.
• Industrial-grade workflow export: Natively supports exporting generated scenes as Gaussian Splats, textured meshes, and panorama video formats, connecting perfectly with professional development engines such as Unreal Engine 5 and Unity.
• Infinite environment expansion and stitching: Breaks the capacity limit of a single scene, using the Studio module to seamlessly stitch multiple generated virtual worlds, helping developers build extremely large macro digital environments.

Who It's For This tool is tailor-made for concept designers, game environment artists, pre-vis teams in film VFX, and VR/AR immersive content creators. It also gives architects and interior set designers the best way to complete spatial validation and high-fidelity presentation of their plans in very little time.

Unique Advantages Completely unlike current mainstream AI tools that can only generate standalone objects or topological characters (such as Luma AI and Meshy), Marble owns the niche of scene-level Gaussian splat generation. It focuses intensely on building grand physical environments, and with outstanding spatial stability and a professional asset export pipeline, it is the closest to commercially deployable scene-building AI on the market.

Editor's Review Marble is unquestionably a stunning paradigm shift, truly breaking the wall between 2D concept art and 3D physical space. Although limited by the early-stage nature of Gaussian splatting technology, with room for improvement in fine edge details and complex dynamic physical interactions, the extreme immersion and ultra-fast workflow it provides already hold revolutionary potential to reshape the pre-production pipelines of the film and game industries — a spatial intelligence pioneer tool we highly recommend.
