Model selection exchange

[pszwan84]

Hello, I’m Zhantao Wang, currently working/studying at Digital China. I have experience in AI. I am passionate about open-source projects and hope to contribute to the community through this PR.

In this PR, my main goal is to implement functionality that allows users to select different models, enabling flexible switching between models from various vendors based on their needs. This will enhance the project's scalability and user experience. I look forward to your feedback and hope to contribute to the further development of the project.

Thank you for taking the time to review my PR!
