Here are some example URLs that should open in new tabs:

- [Hugging Face Homepage](https://huggingface.co)
- [GitHub Repository](https://github.com/ggml-org/llama.cpp)
- [OpenAI Website](https://openai.com)
- [Google Search](https://www.google.com)

You can also test inline links like https://example.com or https://docs.python.org.

All links should have \`target="_blank"\` and \`rel="noopener noreferrer"\` attributes for security.`,
