Hi @markpollack , sorry to bother you, I noticed there have been some recent refactorings to the code. Do these model client PRs also need to be adjusted accordingly?

@tzolov hi, sorry to bother you, it seems Mark is on vacation...
this PR has completed the refactoring, has been squashed and force pushed again, and also added support for function calls.

I sent the API keys for Moonshot and others model provider's key to Mark via email before.
I'm not sure if Mark has shared them with you.
If you need them, please contact me and I can provide them again, including QianFan on #751 and DeepSeek #702

Wow, welcome back, I just checked the emails, and the API keys for Deepseek and Moonshot were sent before.
I noticed that i haven't sent the API key for Qianfan, so I just sent you a new email with it.
but the balance in it is not very much, but it should be enough for testing, If the balance is insufficient, please contact me.

Merged in d5b8123 made a few minor changes. Note that BeanOutputParser is deprecated, so the tests should use BeanOutputConverter and other similar OutputConverter classes.

The api keys you sent worked!
