This PR significantly enhances the model card by:
- Linking the model to its official Hugging Face paper page at https://huggingface.co/papers/2507.03112.
- Adding the `text-generation` pipeline tag, which helps users discover the model at https://huggingface.co/models?pipeline_tag=text-generation.
- Specifying `transformers` as the compatible library, enabling the "Use in Transformers" widget.
- Including relevant `tags` such as `dialogue`, `empathy`, `reinforcement-learning`, and `qwen` for better discoverability.
- Providing a direct link to the GitHub repository.
- Incorporating the full paper abstract and a key framework image.
- Providing a comprehensive usage example for inference with the `transformers` library, including handling the Qwen2 chat template.
- Adding a BibTeX citation.
These changes aim to greatly improve the model's visibility, usability, and documentation for the community.
