VGGT-1B

VGGT-1B

Infers a scene's 3D structure from one, a few or hundreds of images in a single forward pass, including camera parameters and depth maps. It suits computer vision developers and researchers.

About

What it is: VGGT, the Visual Geometry Grounded Transformer, is an image-to-3D model from Meta AI Research and the University of Oxford's VGG group. It is a feed-forward neural network that reads images of a scene and infers its key 3D attributes directly. The work was presented at CVPR 2025.

It reports the cameras' settings and positions, then adds point maps, a depth map for each view and tracks of 3D points. The input can be one view, a few views or hundreds, and the answer arrives within seconds.

Who it suits: Computer vision developers and researchers who need 3D facts about a scene from ordinary pictures suit it best. You work with it in Python.

Industry | Who uses it | How they use it | Example
3D and graphics | Computer vision engineers | Recover scene geometry from a set of photos | Get depth maps and a point map from a few views
Robotics | Robotics researchers | Estimate camera parameters for images of a space | Read the extrinsic and intrinsic camera parameters
Academic research | Research students | Study feed-forward 3D reconstruction | Follow 3D points across several views

Anyone who wants a finished 3D app can skip it, because this page holds a model and not a ready-made tool.

Where to use it: You run it yourself in Python, using the code that the model page points to.

• Windows, macOS or Linux with Python installed
• The project's own code repository on GitHub, named on the model page
• The Hugging Face demo page, which the model page links to

Use case | Who | What they get back
Scene geometry from photos | Computer vision engineers | Depth maps and point maps for each view
Camera estimation | Researchers | Camera parameters that place each image in the scene
Point tracking | Research students | 3D point tracks across the views you give it

How to set it up: You need Python and the project's code, since the model page defers its run steps to the code repository.

• Python on Windows, macOS or Linux
• Enough disk space for weights of about 5 GB in F32
• The project's code repository, for the run instructions

1. Install Python.
2. Install the Hugging Face hub tools with pip.
3. Download the model files with the hf command.
4. Follow the quick start in the project's code repository.

pip install -U huggingface_hub
hf download facebook/VGGT-1B

How to use it: The model page shows no commands of its own and sends you to the project's code repository for the quick start. You give the model one image, a few or hundreds of a scene. It answers with the cameras' settings and positions, point maps, depth maps and tracks of 3D points.

Example: You give the model a handful of photos of one scene. It returns where each camera sat, a depth map for each view, a point map of the scene and tracks of 3D points, all within seconds.

For newcomers and experts: Think of the model as something that looks at several pictures of a place and works out its 3D shape and where each camera stood. Your first small try is to download the files, then open the quick start in the code repository.

Under the hood, one feed-forward pass infers every key 3D attribute at once, so there is no separate step for each output. It accepts anything from a single view to hundreds, which makes the number of images a choice you make. The record lists 1.3B parameters.

One, a few or hundreds of images go in
A feed-forward transformer reads the views
Camera parameters, point maps and depth maps
3D point tracks come out too

Good to know: The license limits the model to non-commercial use.
