The team is headed to LA next week for SIGGRAPH. Excited for the Worlds in Action Hackathon this weekend and a week of conversations with world builders, creators, and researchers. If you'll be around, we'd love to meet you. See you soon! 👋 Events below.

Join us at Worlds in Action Hackathon during SIGGRAPH 2026! From multiplayer games to immersive interactive experiences, here's a look at what's possible with Marble across Unity, Unreal Engine, and the web with three.js Los Angeles • July 18–19

The future of AI should be grounded in human agency, creativity, and understanding. @FastCompany explores the rise of world models and features insights from World Labs cofounder @drfeifei: "Her vision for World Labs—and its human-centered future—is both consistent and persistent. It's like a simulation in her world model. Once in place, it stays put." Read the full article here ↓

Today we are sharing three new research papers, each exploring a new way to generate 3D content by leveraging large-scale generative models and 2D priors. These projects were led by our incredible interns @HaoZhang623 @BDuisterhof @DrTunnels [1/4]

OpenArt now lets you turn a single image into a persistent 3D world creators can direct with precise control. Wide shots, top-down views, over-the-shoulder framing. All from the same environment, acting like a permanent virtual set. Powered by the World Labs API. Learn more ↓

Generate an interactive 3D world ✨ I opened this project in Cursor and uploaded an image of a cozy bookstore. The agent then generated the environment, chose objects to turn into 3D meshes, added colliders, and created sound effects 🤯

Turn a single image into a fully meshed 3D world in minutes 👀 Built by a World Labs team member, image-blaster combines Marble + Claude skills + @fal to generate 3DGS environments, meshes, interactive physics objects and SFX from one image. learn more + try it yourself ↓

Dormant Memories — a gallery regrouping my recent experiments built from real-world captures, reconstructed as 3D Gaussian Splats, and in many cases manipulated using @theworldlabs' Marble. Everything is built with Spark, the 3D Gaussian splat renderer released by World Labs. It runs in the browser and can be experienced across devices: desktop, mobile, and headsets like Apple Vision Pro and Quest 3. This work comes out of something I've been exploring for a few years now: capturing fragments of the world (places, objects, moments...) and turning them into spaces that can then be revisited, manipulated, and explored in real time. What particularly interests me here is the process of creating alternate versions of the same place; starting from something that physically exists and using it as a base to explore variations, instead of generating from scratch. These explorations are part of what we do at @bonjourdpt... same tools, same curiosity, same collaborative energy that shape the studio's work on interactive and immersive experiences. Some of these experiments were featured as part of the Spark 2.0 release by World Labs. Their technical blog post is a must-read; link in the thread ↓ These are experiments. They aren't fully optimized, they aren't bug-free, and the UX has rough edges. The goal is to explore, test, and learn. #GaussianSplatting# #3DGS# #pointcloud# #WorldModels# #sparkjs# #threejs#

2 Weeks. New Tools. Infinite Worlds🚀 The World Jam is LIVE. Build the future of interactive 3D with Marble 1.1 + Spark LoD. Join our Discord to start building. More info below 👇

We built Spark 2.0 to bring the most ambitious 3DGS worlds to the web🌍 Making high-fidelity 3D accessible on any device is a big step for spatial storytelling. We’re proud to share this open-source renderer capable of streaming 100M+ 3DGS to unlock a new era of world building!
