This seems like by far the best model yet for reconstructing 3D spaces from sparse images. It looks like you could reconstruct your whole house with pretty good fidelity from a dozen or so images taken on your phone. They show it working with videos that have motion, but it seems like time is always frozen while the camera is moving, and they always return to a ground truth camera view before advancing time again. Maybe the temporal consistency isn't very good? This surprises me given how well it understands space. I guess modeling physics and time is the next step in the development of this kind of model.
- jcjohns 1mo ago
  In addition to frozen time, Atlas can handle some scene motion - see for example the candy New York City in the Camera-Controlled Generation section where cars are moving, or some subtle motion of the waves toward the end of the 1-minute video example. But this is certainly one area we plan to improve going forward.

What exactly does world model mean? Ive seen it used so many times in so many ways to just describe SOTA anything its lost its meaning.
- KaiserPro 1mo ago
  It means everything to everyone. However essentially a world model is something that has the understanding of 3d world and can generate novel view point given either text or image input. The use I have seen is for robotics. You feed in the current view and describe the action you want it to do, and then it plans the arm movements. (really useful for softbody manipulation. There are other meanings. but essentially a world model is able to reason in 3d, rather than text.
- bluecalm 1mo ago
  It means it builds internal representation of the world it understands (can do physics on/predict/modify) and then renders it.
- CSMastermind 1mo ago
  It's an overloaded term for AI models that have spatial reasoning LLMs currently lack. Best definition I've heard is: AI systems that can build an internal map of their surroundings to anticipate what happens next and make decisions based on their predictions about the consequences the different actions they can take would have. There's a bunch of different approaches people are trying: - World labs (linked in this post) is going down the route of neural 3D representation work (NeRFs, 3D Gaussian Splatting) - Yann LeCun is pretty famously betting on JEPA architectures (check out the excellent Welch Labs videos for more) - Google is betting on generative video - Karl Friston was pursuing 'active interference,' which is just traditional RL techniques with different reward functions
  - jcjohns 1mo ago
    Small correction, World Labs isn't betting exclusively on explicit 3D -- many of the Atlas results in this post are generated frames without any explicit underlying 3D representation. But Atlas can (optionally) output explicit 3D for the cases where you know you want it.
- jcjohns 1mo ago
  It's an overloaded term that different people use for different things. At World Labs we think about three major categories of world models: - Renderers output pixels or views of a world, either the real world or a generated world - Simulators predict how the world responds to actions - Planners predict actions for an agent to make to affect some change in the world Under this taxonomy, Atlas is somewhere between renderer and simulator. It predicts high-quality views of a consistent 3D world (renderer) but it can also predict explicit 3D to aid in simulation. Atlas doesn't currently predict actions to directly drive a robot, so it isn't natively a planner; but its simulation abilities can help train another model to be planner.

> For robotics, reconstruction is only half the job: as a simulated robot moves through space, Atlas also generates the RGB and depth data its sensors would observe along the way. The world and the robot's view of it come from the same model. Potentially very significant for accelerating the data flywheel challenge for robotics

Any ideas if it keeps continuity - when you turn around, is the invented chair still there, or does everything shift like in a dream?
- dmarcos 1mo ago
  I believe so. This is not a model that generates pixels frame by frame from user input like genie 3. Instead, there’s an actual 3D scene / structure generated (point cloud, 3dgs) from the input images.

    Wrong, it does go straight to generating images.
    - dmarcos 1mo ago
      From blog post: “It generates both image frames from novel views and explicit 3D outputs” Model can indeed generate novel views but I don’t think in real time (I could be wrong). If you want to navigate a space in real time as user above was asking gotta rely on the 3D output and the explicit representation will provide continuity. User likely was referring to the limitations we’ve seen on video-style world models like genie and precursors.
- jcjohns 1mo ago
  Yes, one of the main goals of this model was to keep 3D consistency as the camera moves around; it can do this even without relying on an explicit 3D point cloud or Gaussian splat representation of the scene.
  - exe34 1mo ago
    Amazing! Thanks for explaining!

I'm a cofounder at World Labs - happy to answer questions about Atlas!
- stranded-man 1mo ago
  spacial context feature is cool - what are the limitations, if any? What would it take to geo and rotation tag every photo ever taken , combine it into a mass spatial context, run it through atlas and build an entire 3D model of the world?
  - keunhong 1mo ago
    Atlas project lead here. Atlas is an auto-regressive diffusion model, so context length limitations apply similar to LLMs and video models. Where Atlas has an edge is that its context comprised of an arbitrary sequence of images with camera poses, which lends itself to managing the context in creative ways (we called this "context juggling" in our RTFM blog, https://www.worldlabs.ai/blog/rtfm https://www.worldlabs.ai/blog/rtfm). So yes through clever context management you could potentially build an entire 3D model of the world.
    - stranded-man 1mo ago
      can atlas also generate 3D without pose information attached to the input images?
      - jcjohns 1mo ago
        Yes, as long as the input images are "poseable" -- if they were taken in the same space they need to have some overlap, where the same object or part of the scene is visible in multiple views so the pose can be predicted. You can also manually position the input images in 3D space to create scenes generatively; we show examples of this in the "generating with spatial context" section
    - cman1444 1mo ago
      Would it be more reasonable to take images from movies and create worlds of various IPs? My first thought is a detailed Hogwarts that is fully explorable using scenes from the movies (or even descriptions from the books?)
megaman821 1mo ago
Can a reconstruct distinct areas of a larger area with a "fog of war" in between, or will it hallucinate the unknown areas?
- jcjohns 1mo ago
  It can operate in different modes for different applications. If you only want to reconstruct the content in the input images without any imagination, Atlas can do sparse 3D reconstruction where it predicts a depth map for each input pixel, without predicting anything occluded or not visible in the input views. This could be used to implement your "fog of war" view. But sometimes you want the model to stitch together views and imagine a coherent completion; this is a powerful tool for building and authoring generative worlds. For example the 1 minute video we show in the post was built by positioning seven unrelated input images in space and prompting the model to interpolate between them along a hand-specified camera path.
Vakaiser 1mo ago
This is incredible. One potential application that I'm thinking about already is the rapid iteration of video-game map blocking. Being able to drop in some 'initial state' configuration and then have it procedurally generate a handful of alternative configurations could make rapid prototyping a significantly quicker experience, especially if you wanted to see what a potential end result could look like. Furthermore, being able to extract and process world geometry and 3D objects from Atlas could reduce friction in the early stages of indy development, where developer time is stretched thinner. I'm very excited about AI tooling moving forward if this is a glimpse into the future.
- soundworlds 1mo ago
  Yeah where I've been previously skeptical for using AI in creative ways, basically when these tools get to the point where you have a tight iteration loop, it enables a great creative flow. You still need the technical proficiency to be able to make edits beyond that, but I think studios would be foolish to let go of their experts in the first place.
  - chriswen 1mo ago
    Atlas will complement Marble, our current product that can be used for applications like this nicely :) These are indeed great applications for the model. Atlas gives us unprecedented levels of control as well as generative capabilities and is 3d consistent.
- Stevvo 29d ago
  This is completely useless for video game map blockout. You need collisions for level blockout, which this does not provide. It makes gaussian splats, not geometry.
  - Vakaiser 29d ago
    3DGS to Mesh conversion does exist: https://www.kiriengine.app/blog/what-is-3dgs-to-mesh https://www.kiriengine.app/blog/what-is-3dgs-to-mesh Furthermore, AI can be used to generate 3D primitives from Gaussian splats and point clouds. Sure, it would require an intermediary stage should the Atlas team not build it into a first-class offering, but the process is not exactly untenable.
teraflop 1mo ago
The blog post doesn't seem to mention what strikes me as the most interesting application of a model like this, namely extracting semantic information from its latent space. It mentions robotics applications, but only in the context of generating realistic world models for simulation. If you have a robot deployed in an environment, generating synthetic views of the environment you're in doesn't have any obvious value. What does have obvious value is the latent knowledge that the model could have used to generate those synthetic views. For instance, the fact that Atlas is capable of identifying regions of the input images that look like "floors", and smoothly interpolating them and filling in gaps with more floor, suggests that it has a concept of "floor-like walkability" which it's learned from the examples in its training data. And being able to identify the regions of 3D space that correspond to that semantic label would obviously be useful for robot path planning. There's plenty of literature about e.g. using neural networks to estimate walkable areas from a point cloud. And you could imagine just bolting one of those methods to the front of Atlas, using the synthesized point cloud (instead of traditional photogrammetry or LIDAR) as input. But that seems like it's throwing away a lot of potentially useful semantic information, on top of being needlessly inefficient.
- iandanforth 1mo ago
  What is the scenario you're thinking about? This is kinda what happens with VLAs, the latent knowledge of an LLM can help in action generation pipelines, but it's also kinda slow.
- JohnnyAPI 1mo ago
  As a World Labs customer, I suspect they are using existing 3D assets when creating their environments. For one thing, a vendor of 3d models for AI mentioned Word Labs as a customer on a webinar. I don't know if that undercuts what you're saying entirely. But if they're just protecting the splat in real-time based on the camera path through a 3d world, would the model truly understand that it's a floor?
- chriswen 1mo ago
  Sounds like something Atlas probably is a great base model for.
xyzsparetimexyz 1mo ago
How fast can it generate a frame? If its fast enough for real time then you wouldn't need to pipe the outputs to a different novel view synthesis method like Gaussian splats.
ACCount37 1mo ago
It's a promising approach - and the demo goes to show just how advanced and robust "3D from 2D" reconstruction is now. Dedicated depth sensors used to be a must on advanced robotics platforms - the only way to get anything close to reliable 3D point clouds was to spin a LiDAR. But by now, I wouldn't be surprised to see more and more robots ship with smartphone-like camera blocks - varying FoVs and focal depths, but not a lot of explicit depth sensing, if any at all. Also, I wonder if this very model can be retrofit into a true robotics VLA? If it already takes text and image guidance, performs autoregressive diffusion of novel views, and handles temporal dynamics - why not diffusion of actions too?

ecthiender 29d ago
Looks very very interesting. For my immediate use-case to simulate a real-world 3D space, would it work with exact dimensions? Like can I give it exact dimensions and then can it render it truthfully? For example, I want to say I have walls of 8ftx5ft, and I have N paintings of so-and-so specific sizes (I have the exact sizes), is it able to use the dimensions exactly?
RALaBarge 29d ago
Assuming you had a 1:1 scale, what would be the difference between you taking a camera of an environment and measuring everything the same way vs. it being generated artificially in a 3d space? Wouldn't the inputs be more or less the same wrt training a model with the synthetic data vs live video and the data captured there?
