World Labs

What World Labs does

World Labs Technologies, Inc. is a San Francisco-based spatial intelligence company founded in early 2024 by Fei-Fei Li, Justin Johnson, Christoph Lassner, and Ben Mildenhall. It builds Large World Models (LWMs), a family of proprietary multimodal AI systems that perceive, generate, reason about, and interact with three-dimensional environments, anchored on 3D Gaussian Splatting, Neural Radiance Fields, and learned rendering techniques. The commercial flagship is Marble, launched in November 2025, which generates spatially consistent, persistent, navigable 3D worlds from text, images, video, 360 panoramas, or coarse 3D layouts and exports them as Gaussian splats, meshes, or video. The platform is augmented by Spark, an open-source 3DGS renderer for the web (Spark 2.0 with Level-of-Detail streaming), and by RTFM, a research-preview real-time generative world model running on a single H100 GPU.

World Labs monetizes through a freemium and tiered subscription model on the Marble web app (free personal tier plus paid Standard, Pro, Max tiers topping out at $95/month), a Pay-As-You-Go developer API at platform.worldlabs.ai using Service Credits, and custom multi-year enterprise Order Forms with commits and sublicensing rights. Go-to-market blends product-led growth (self-serve Marble web app, Discord developer community, open-source Spark) with enterprise distribution via a strategic Autodesk advisory partnership (integrating into AutoCAD, Revit, Maya, Fusion) and an NVIDIA Isaac Sim co-marketed workflow for robotics simulation customers. Reported paying use cases span virtual film production, architectural design, and robotics training.

The company has raised approximately $1.23 billion across a September 2024 seed round ($230M at a $1B valuation), a November 2025 Cisco strategic investment via Convertible Preferred Stock, and a February 2026 $1B round at an approximately $5B valuation anchored by a $200M Autodesk investment with participation from AMD, NVIDIA, a16z, Emerson Collective, Fidelity, and Sea. It employs 11-50 people and operates globally subject to standard U.S. export controls and age-of-majority restrictions.

Revenue model

1. Marble Subscription Tiers: Tiered monthly recurring subscriptions (e.g., Standard, Pro, Max) that allocate monthly Service Credits for use of Marble; unused credits expire at the end of each billing period and do not carry forward, with overage charges billed at next cycle.
2. API Pay-As-You-Go: Usage-based API consumption billed via Service Credits purchased independently of subscriptions; includes minimum initial purchase, rate limiting, concurrency limits, and credit expiration within one year of purchase.
3. Marble Free Tier: Free account access to Marble for personal, non-commercial use of generated outputs; provides top-of-funnel acquisition and usage data for AI Model training under World Labs' non-exclusive license.
4. Top-Up Credits: One-time purchases of additional Service Credits beyond subscription allocations; remain valid for one year (Top-Up Period), carry over month-to-month, and are consumed after subscription-allocated credits are exhausted.
5. Enterprise Order Form Licensing: Custom Order Forms for Paid Account Users and API integrations granting commercial rights to Outputs, sublicensing rights for downstream applications, and bespoke commitments/renewal terms with annual or multi-year cadences.

Core offering

World Labs builds and sells Large World Models (LWMs) and related tools that generate spatially consistent, persistent, navigable 3D worlds from multimodal inputs. Its flagship commercial product, Marble, is offered through a self-serve web app with tiered subscriptions and a free tier, alongside a pay-as-you-go developer API that exposes the models programmatically. The offering is completed by Spark, an open-source 3D Gaussian Splatting renderer for the web, and RTFM, a research-preview real-time generative world model.

Product overview

World Labs offers a spatial-intelligence platform centered on Marble, its flagship multimodal world model that generates persistent, navigable 3D worlds from text, images, video, 360 panoramas, or coarse 3D layouts, with interactive editing, world expansion, and export to Gaussian splats, meshes, and video. The platform is augmented by Spark, an open-source 3D Gaussian Splatting renderer built on Three.js with WebGL2 (currently Spark 2.0 with Level-of-Detail streaming) used to render Marble outputs on the web, and by RTFM, a research-preview generative world model that produces video in real time as users interact with generated scenes. The World Labs API exposes these proprietary AI Models to developers under PAYG billing with rate limiting and concurrency controls, enabling integration of spatial intelligence into customer-facing applications.

Products and services

• Marble World Labs' flagship multimodal Large World Model that generates spatially consistent, high-fidelity, and persistent 3D worlds from text, images, videos, 360 panoramas, or coarse 3D layouts. Supports interactive editing, world expansion and composition, and export to Gaussian splats, meshes, and video for downstream tools, with outputs compatible with Unreal Engine, Unity, and CAD/BIM pipelines. Available through marble.worldlabs.ai to creators, studios, and developers.
• Spark Open-source dynamic 3D Gaussian Splatting (3DGS) renderer built on Three.js with WebGL2 for the web, distributed via sparkjs.dev and GitHub. Spark 2.0 streams and renders very large 3DGS scenes (100M+ splats) interactively across desktop, iOS, Android, and VR browsers, and is the standard rendering layer for Marble outputs in third-party applications.
• RTFM (Real-Time Frame Model) Research-preview real-time generative world model that generates video frames in real time as users interact with generated 3D scenes. Implemented as an autoregressive diffusion transformer trained end-to-end on large-scale video data, running inference on a single H100 GPU with unbounded persistence via posed-frame spatial memory.
• World Labs API Developer API exposing World Labs' AI Models, including Marble, for programmatic access. Operates on a pay-as-you-go basis using Service Credits with rate limiting, concurrency limits, usage quotas, and API-credential authentication, enabling integration of world models into customer-facing applications and downstream pipelines.

• Blockade Labs: Blockade Labs (Skybox AI) generates 3D environments and 360° worlds from text prompts, directly overlapping Marble's text-to-3D-world use case for creators, games, and VFX.
• Tripo3D: Tripo3D offers AI-driven 3D model and scene generation from text and images, a directly comparable service to Marble for rapid 3D asset and world creation targeting game developers and creators.
• Meshy: Meshy provides AI text/image-to-3D model generation with an API and creator tooling, serving the same creator and developer segments as Marble for fast 3D content production.

Broad incumbents

• NVIDIA (Cosmos): NVIDIA's Cosmos world foundation models and Isaac Sim platform are a direct overlap in robotics simulation and world models; NVIDIA is also a strategic investor and partner, making it both a competitor and an enabler for World Labs.
• Google DeepMind (Genie): DeepMind's Genie interactive world-generation models target the same spatial intelligence frontier as World Labs, with substantially larger research and compute resources, positioning it as a formidable frontier-model competitor.
• Unity: Unity operates the dominant real-time 3D engine used for games and simulation, integrating generative AI for world and asset creation, and serves many of the same downstream customers as World Labs in gaming, AEC, and digital twins.
