+
+This repository hosts the **model weights** for PhysRVG (ECCV 2026). PhysRVG leverages a unified reinforcement learning framework with verifiable rewards to improve rigid-body motion generation in video synthesis.
+
+> 📌 Demos, training, and inference code are in the [**GitHub repository**](https://github.com/ant-research/PhysRVG). This page only provides the checkpoints.

+```
+
+## Usage
+
+Download the weights into the `./models` directory of the [code repository](https://github.com/ant-research/PhysRVG):
+
+```bash
+huggingface-cli download HappyP4nda/PhysRVG --local-dir ./models
+```
+
+Then run inference (see the GitHub README for setup):
+
+```bash
+python inference.py --video_path data/example_videos/2/video.mp4
+```
