## 😮 Highlights
Video-LLaVA exhibits remarkable interactive capabilities between images and videos, despite the absence of image-video pairs in the dataset.
### 💡 Simple baseline, learning united visual representation by alignment before projection
- With **the binding of unified visual representations to the language feature space**, we enable an LLM to perform visual reasoning capabilities on both images and videos simultaneously.
### 🔥 High performance, complementary learning with video and image
- Extensive experiments demonstrate **the complementarity of modalities**, showcasing significant superiority when compared to models specifically designed for either images or videos.
## 🤗 Demo
### Gradio Web UI
