World Labs Unveils Marble 3D Multimodal Model and Marble Labs Workspace
When I first saw the demo, the thing that stuck with me was the way Marble turns a simple sketch into a walk-through scene. Fei-Fei Li’s World Labs just rolled out this multimodal model, letting developers and artists spin up three-dimensional environments from text, images or even rough drawings. The twist?
It’s not locked behind a research-only API - it’s meant for anyone to try, which nudges the tech out of the lab and into everyday creative tools. Alongside Marble, the team is launching Marble Labs, a sort of curated hub where users can poke around workflows, read case studies and grab documentation - stuff that could shave weeks off the learning curve. At the same time, startups like Decart and Odyssey are already playing with similar 3D tricks, so the pressure to build a helpful ecosystem feels real.
I’m not sure yet whether World Labs will become the go-to spot for artists, engineers and designers to push boundaries and swap results, but that’s the promise they’re putting on the table. In their own words, they summed it up pretty plainly:
Alongside the launch, World Labs introduced Marble Labs, a workspace for creators to explore workflows, case studies, and documentation. "It is where artists, engineers, and designers push the boundaries of world models," the company said. There are many other startups like Decart and Odyssey building world models and putting out free demos, and Google's Genie is still only in a research preview.
Marble supports text-to-world and image-to-world generation, as well as multi-image and video inputs for greater control over scene structure. Worlds can be exported as Gaussian splats, triangle meshes, collider meshes, or videos with pixel-level camera control. Marble now includes AI-native world editing tools, enabling object removal, style changes, and structural modifications.
World Labs also unveiled Chisel, an experimental 3D sculpting mode that lets users design coarse layouts and apply styles through prompts. "Chisel decouples structure from style," according to the company. Users can expand worlds through one-step enlargement or compose multiple worlds to build large spaces.
Marble’s hype is big, but does it deliver? World Labs claims the system can spin up 3D scenes from a line of text, a sketch, a video clip, or a rough layout, and lets users tweak the world in real time. The tool just left beta after two months with a handful of early users, yet they haven’t published any hard performance numbers.
The startup pulled in $230 million last September, so cash isn’t the bottleneck - the question is how fast creators will actually fold Marble into their workflows and whether the price tag makes sense. Marble Labs, the companion workspace, ships case studies and docs and markets itself as a sandbox for artists, engineers and designers to play with world models. That sounds ambitious, but we’ve yet to see solid examples of the output quality.
Meanwhile, rivals like Decart and Odyssey are also rolling out multimodal 3D kits, so the market is already busy. It’s hard to say if Marble will carve a niche or just become another option on the shelf. For now it’s publicly available; its real impact will hinge on how smoothly it slots into existing creative pipelines.

Common Questions Answered
What input modalities does the Marble multimodal model accept for generating 3D environments?
Marble can generate three‑dimensional worlds from text prompts, static images, video clips, and rough layout sketches. This multimodal capability lets developers and artists choose the most convenient medium for their creative workflow.
How does the Marble Labs workspace support creators using the Marble model?
Marble Labs provides a dedicated workspace that includes curated workflows, case studies, and extensive documentation. It is designed for artists, engineers, and designers to experiment with world‑building, share best practices, and accelerate integration of the model into production pipelines.
What is known about Marble's performance metrics after its two‑month beta period?
The model completed a two‑month beta with early adopters, but the company has not disclosed specific performance metrics such as generation speed or fidelity. As a result, potential users must rely on qualitative feedback until quantitative data is released.
In what ways does Marble differ from competing world‑model projects like Decart, Odyssey, and Google's Genie?
Unlike Decart and Odyssey, which offer free demos, and Google's Genie, which remains in a research preview, Marble is launched for public use with a full commercial offering. This positions Marble as a more production‑ready solution, though its cost and adoption rate are still uncertain.
