"The launch of the generative world model, first released in limited beta preview two months ago, comes a little over a year after World Labs came out of stealth with $230 million in funding, and puts the startup ahead of competitors building world models. World models are AI systems that generate an internal representation of an environment, and can be used to predict future outcomes and plan actions."
"Startups like Decart and Odyssey have released free demos, and Google's Genie is still in limited research preview. Marble differs from these - and even World Labs's own real-time model, RTFM - because it creates persistent, downloadable 3D environments rather than generating worlds on-the-fly as you explore. This, the company says, results in less morphing or inconsistency, and lets users export worlds as Gaussian splats, meshes or videos."
"Marble is also the first model of its kind to offer AI-native editing tools and a hybrid 3D editor that lets users block out spatial structures before AI fills in the visual details. "This is a brand new category of model that's generating 3D worlds, and this is something that's going to get better over time. It's something we've already improved quite a lot," Justin Johnson, co-founder of World Labs, told TechCrunch."
Marble is a commercial generative world model that transforms text prompts, photos, videos, 3D layouts and panoramas into persistent, editable, downloadable 3D environments. The product is available via freemium and paid tiers and supports export as Gaussian splats, meshes or videos. Persistent environment generation reduces morphing and inconsistency compared with on-the-fly world rendering and enables full exports for offline use. Marble introduces AI-native editing tools and a hybrid 3D editor that lets users block out spatial structures before AI fills in visual details. The launch follows a limited beta preview and comes after World Labs raised $230 million and exited stealth.
