# Model Card for InternVideo2 (Vision-Only)

This model card describes the **vision encoder** component extracted from the InternVideo2 foundation model series.

## Model Details

This checkpoint contains only the vision backbone parameters, suitable for video or image feature extraction tasks. It was obtained by filtering a multimodal InternVideo2 checkpoint (e.g., S2_6B).

### Model Sources

- **Original Project Repository:** [InternVideo2](https://github.com/OpenGVLab/InternVideo/tree/main/InternVideo2)
- **Original Paper:** [2403.15377](https://arxiv.org/abs/2403.15377)
- **Original Point of Contact:** mailto:[InternVideo Group](gvx-sh@pjlab.org.cn)

### Uploader

- **This specific vision-only checkpoint uploaded by:** [qingy2024](https://huggingface.co/qingy2024)

## How to Use

This file (`InternVideo2_S2_6B_vision.pt`) is a standard PyTorch state dictionary containing only the vision encoder weights. It can be loaded into a compatible vision model architecture using `model.load_state_dict()`.

```python
import torch

vision_state_dict = torch.load("InternVideo2_S2_6B_vision.pt", map_location='cpu') # or 'cuda'
```

## Limitations

This model contains only the vision encoder. It **does not** include the text or audio encoders and cannot perform tasks requiring multimodal inputs unless combined with separate models for those modalities.
