This demo allows users to manually select which visual tokens to send to the LLM to observe how different visual tokens impact the final response.

### Instructions:
1. Upload an image.
2. Select the visual tokens.
3. Generate the answer.

For a step-by-step guide, refer to the [Usage Video](https://youtu.be/9GNIJy4U6-k?si=jcWIJ2O0IjB4aamm).
