Title: [Feature Request]: Select the request format based on the model service provider + model name, rather than simply relying on the model name

Problem Description

There are the following scenarios:
Get the gemini-pro model of the openai request format through one-api, that is, the request format is similar:

POST {{one_base}}/v1/chat/completions
Content-Type: application/json
Authorization: Bearer {{one_key}}

{
  "model": "gemini-pro",
  "messages": [
    {
      "role": "system",
      "content": "You are a helpful assistant."
    },
    {
      "role": "user",
      "content": "hello"
    }
  ],
  "stream": true
}

If you fill in one_base as the custom endpoint of openai, fill in one_key, and the custom model gemini-pro, you will still be prompted to configure Google as the model service provider.

I believe there are many similar situations. In fact, if you transfer the API through one_api, you can easily implement multi-endpoint and multi-key polling using the openai API client. Just make sure that the API format that makes the request is not simply distinguished by the model name.

Solution Description

My solution to this problem is:

1. Differentiate custom model settings. Each model service provider can configure corresponding custom models.
2. Use model service provider + model name to uniquely describe the request format allowed by a model.
3. The existing image recognition function can distinguish based on the model name, and the model service provider only distinguishes the request format.
4. Determine the model name and request format (OpenAI/Google/Azure, etc.) based on the model name (service provider) selected by the user

可以one-api里设置别名，next-web里再设置回显示名。

You can set the alias in one-api, and then set the display name back in next-web.
