[Request] 增加兼容OpenAI的自定义模型

[goodtime123456]

🥰 Feature Description

比如这个https://github.com/LLM-Red-Team/kimi-free-api 如果把转换的key和代理填到第一个OpenAI的位置，那原本自带的默认的ChatGPT就用不了。

🧐 Proposed Solution

希望再增加一个模型选项，可以叫自定义模型（兼容OpenAI接口）。 这个模型的作用就是用来填通过各种方式转换成兼容OpenAI接口的代理地址和API Key。这样的话，就可以既保留原生的ChatGPT，又可以在对话中随时切换用其他的兼容模型。
