World Labs is a frontier AI research and product company focused on spatial intelligence. It builds foundational world models that can perceive, generate, reason, and interact with the 3D world, with the goal of turning visual and textual inputs into explorable spatial environments. Its positioning sits at the intersection of generative AI, computer vision, graphics, and simulation.
World Labs is commercializing that research through products for both creators and developers. Marble is its first product, and the company has expanded that foundation with the World API for programmatic access and Spark for web-native rendering. Together, these offerings position World Labs as a platform builder for applications that need persistent, high-fidelity, navigable 3D worlds across creative, immersive, and simulation-oriented workflows.
Offerings, Capabilities, and Integrations
World Labs enables multimodal 3D world creation from text, images, video, panoramas, and coarse 3D layouts. Its capabilities span world generation, targeted editing, world expansion, multi-world composition, cinematic recording, and export of spatial assets for downstream production and development workflows.
The company supports both no-code and developer-led adoption. Its stack covers browser-based creation, programmable world generation, and web rendering for Gaussian splatting experiences. World Labs also supports handoff into game engines, digital content creation tools, VR experiences, and simulation environments, making its spatial outputs usable beyond a standalone app.
Products and Services
- Marble: World Labs’ first product for creating spatially cohesive, high-fidelity, and persistent 3D worlds from text prompts, images, video, panoramas, and coarse 3D structures, with editing, expansion, sharing, and export workflows.
- World API: A public API for generating explorable 3D worlds from text, images, panoramas, multi-image inputs, and video, allowing developers to embed world generation into applications, tools, and simulation pipelines.
- Spark: An advanced 3D Gaussian Splatting renderer for THREE.js and WebGL2 that lets developers render dynamic splat-based scenes in web browsers, including desktop, mobile, and WebXR environments.
- Chisel: Built-in 3D layout control tools that let users block out geometric layouts and architectural structures as a foundation for more controlled world generation inside Marble.
- Studio: Advanced creation tools for composing multiple worlds into larger environments, arranging scenes, and producing cinematic camera animations and recorded flythroughs.
- World Labs Platform: The company’s developer-facing platform for accessing the World API, managing API keys, purchasing credits, monitoring usage and billing, and working from documentation and sample projects.
Target Customers
World Labs targets creative professionals and studios working in art, film, VFX, virtual production, gaming, AR/VR, and immersive media. Its products fit teams that need faster ways to generate, refine, and reuse consistent 3D environments without relying entirely on manual modeling workflows.
It also serves developers, robotics and embodied AI teams, architects and designers, and research-oriented organizations that need photorealistic, editable 3D environments for simulation, prototyping, visualization, walkthroughs, or evaluation. The mix of web app, API, and rendering tooling gives World Labs relevance for both individual creators and technically sophisticated product or R&D teams.
