This function allows users to interact with a model and receive responses based on a series of historical messages.
If `stream` is set to True (by default), the response will be streamed in chunks, mimicking the OpenAI-style API.
Set `stream` to False explicitly, the response will be returned in a single complete answer.
Reference:
- If `stream` is True, the final answer and reference information will appear in the **last chunk** of the stream.
- If `stream` is False, the reference will be included in `choices[0].message.reference`.
Example usage:
curl -X POST https://ragflow_address.com/api/v1/chats_openai/<chat_id>/chat/completions \
