Generating Bigger and Better Worlds

Today we're sharing an update on our quest to push the frontier of spatial intelligence and generate persistent, navigable, and controllable 3D worlds. We are also introducing Marble, a limited access beta preview of our model today at marble.worldlabs.ai, where users can view and create 3D worlds.

Given an image or text prompt, our model generates a 3D world that you can explore for as long as you wish — no time limits, no morphing, no inconsistency. Compared to our previous results, our generated worlds are bigger, more stylistically diverse, and have cleaner 3D geometry.

Marble makes our model available for users to start viewing and building worlds today. Enthusiasts and builders can export generated worlds as Gaussian splats and use them in downstream projects. This is particularly easy to do with our open‑source rendering library Spark which seamlessly integrates Gaussian splats into Three.js for building web‑based 3D experiences, and renders efficiently on desktops, laptops, mobile devices, and VR headsets.

Our model's consistency and style adherence now make it possible to build out large worlds by composing individual generations, as shown in the banner video above and the examples at the end of this post.

Better geometry

The ability to navigate and interact with a consistent 3D world lies at the heart of many workflows and use cases for visual creators. Our generated 3D worlds allow for free viewpoint navigation, in the user's browser, at zero cost. In contrast to the limited 3D experience provided by depth maps or point clouds, our worlds have richer geometric complexity and produce more complete 3D worlds, allowing users to look behind and beyond what is visible in the input view.

Our current model is designed to create 3D environments rather than focusing on isolated or central objects, such as people or animals. Sorry to disappoint selfie enthusiasts or loving pet owners — for now.

More diverse styles

One of the most exciting aspects of working with generative AI is the ability to freely iterate over look and feel as part of the creative process. Our model can lift inputs of many varying styles into 3D, from flat and colorful cartoons to realistic and richly detailed imagery, allowing for exploration and iteration to find just the right world for the job.

A glimpse of bigger scenes

Room-sized worlds are a great start, but creators' imagination often extends beyond these boundaries. We want to share a glimpse of what's possible as users compose their generated spaces together to build out much larger environments. Given the stylistic coherence and geometric consistency achieved by our model, it's already fun to be able to navigate, browse, and imagine many use cases for larger worlds like those shown here.

An invitation

We are still in the early days of this journey. What truly excites us is when our users let us know how Marble can supercharge their creativity and productivity by providing the power of world‑building at their fingertips. Some of our early users are already giving us encouraging feedback, and we're eager to hear from more of you as we continue to improve our technology and product.

We invite you to explore worlds on Marble, and sign up to build your own worlds.

Last but not least: if you're excited to help us advance this vision, join us!
