3D is an exciting area where we are still figuring out the right tasks, problem formulations, architectures, and the best ways to scale.
We're sharing some of our ideas here in our first-ever papers from @theworldlabs, led by an awesome set of interns.
Jun 12
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

Scientific research is fundamental to advancing civilization and helping people globally to solve the most critical problems, from medicine to materials, from brain science to physics, and much beyond. This is only possible when scientists have access to the best tools of the time to conduct scientific research, including having access to AI-based tools.

Hadamard thought in image space
World Labs CEO Dr. Fei-Fei Li: "The world is not made of words."
"Language models have given machines an extraordinary command of concepts, vocabulary, and reasoning, but the physical world, virtual or real, runs on a different substrate."
"Where language models learn the statistical structure of text, world models learn the statistical structure of space and time: how light falls on a surface, how a garden looks from an angle no camera has captured, how objects respond to force and follow the laws of physics."
"Language gave machines a way to talk about that world. World models are how machines will finally come to understand, imagine, reason and interact with it."

Excited to introduce StereoPolicy, led by @EvansXuHan.
📷📷🤖StereoPolicy is an effective way to add geometric cues to modern robot policy models while keeping the strengths of pretrained 2D encoders.
⁉️Why stereo for robot manipulation?
Monocular RGB often lacks the depth cues needed for precise manipulation, while RGB-D and point clouds can be noisy or brittle, especially on reflective and transparent objects in real-world deployment.
Instead of explicitly reconstructing disparity, depth, or point clouds, StereoPolicy directly fuses synchronized left/right RGB views to learn implicit stereo cues, avoiding extra reconstruction latency that can make real-time manipulation difficult.

GPIC should be the new standard benchmark for generative modeling. Training 1 epoch on GPIC is the same cost as 100 epochs on ImageNet, but is a much better proxy for real-world problems. If you work in generative modeling, try GPIC for your next project!
1/ Introducing GPIC: a Giant Permissive Image Corpus and benchmark for visual generation!
🚀100M VLM-captioned image-text pairs for training
📊1M image-text pairs for benchmarking
🖼️~28 trillion pixels
🤗Centrally Hosted
✅Fully permissive for research commercial use
Dataset, benchmark and models🧵👇
Co-led with @KyleSargentAI

It’s a real honor to receive an honorary doctorate of science from @BrownUniversity . 😍
May 24
At its 258th Commencement on Sunday, Brown conferred honorary doctorates on six candidates who have achieved great distinction in a variety of fields, including economics, civil rights, artificial intelligence, national security, business and community leadership. buff.ly/cSP89Ff

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.

Summer vibes ☀️🍃🐱
Built with Marble, Spark, and Three.js. Persistent World Models let you design for cohesive spaces instead of isolated frames.
World Jam ends this weekend! There’s still time to build something magical with Marble. More info 👇

We raised $56M to help build the next era of interactive entertainment. Series B led by @sequoia, Series A led by Sea.
Astrocade lets anyone create games with AI, play them with friends, and share them with millions.
But this isn’t about replacing creativity. It’s about giving more people the tool to bring their taste, humor, stories, and craft to life.
Today, the fun goes public.

Really cool we’re at the point where you can build custom, personalized tools for your own niche 3D workflows.
Built this with GPT-5.5, Spark, and Marble yesterday to get better precision control for creating collider meshes for 3DGS experiences.
