想要加入OPENAI assistant API与fine tuning API的支持,通过对代码的阅读,发现可能要修改bridge_all.py和bridge_chatgpt.py.但这样会破坏整体的统一性.由于对工程代码整体熟悉度不高,可能理解有误.请教作者是否有更好的思路完成该功能,感激不尽

Start by reading bridge_all.py and bridge_chatgpt.py, the files named in the issue, and trace how existing model APIs are unified. Before coding, clarify the intended Assistant API and fine-tuning API scope with the maintainer; done would mean supported workflows that preserve the project's existing abstraction.
