# Matrix-Game 3.5

Matrix-Game 3.5 adds patch memory to keep long 720p rollouts consistent, in first-person and third-person views. You drive it with an anchor image, a camera trajectory and a text prompt.

Organization: Riemann Dynamics. Released: 15 July 2026. Kind: Games.

## What you control

- An anchor image
- A camera trajectory
- A text prompt
- First- or third-person mode

## License

Weights: Available (https://huggingface.co/RiemannDynamics/Matrix-Game-3.5-Distilled). Declared license: Apache-2.0.
The weights' model card declares Apache-2.0, a permissive license that allows commercial use. Check what the model was built on, because a base model's terms can still apply.

## Real-time

Real-time, per authors. 20 fps at 720p, from the paper.

## How to run it

1. Clone the Matrix-Game-3.5 repository, create a Python 3.10 conda environment, and install PyTorch for your CUDA version and requirements.txt.
2. Download Matrix-Game-3.5-Base (and Matrix-Game-3.5-Distilled for the distilled first-person model) from Hugging Face.
3. Also download Wan2.2-TI2V-5B, which supplies the text encoder and VAE, and Depth-Anything-3, which the memory uses.
4. Run infer.py with --person first or --person third; third-person mode can take reference crops to fix the protagonist's look.

## Where to try

No hosted destination verified.
