[redreamality]

load_dotenv(".env")

OPENAI_API_BASE is for Azure right? I don't know whether openai also needs to set this parameter..
The environment variables here are all configured by the user through the client, and then I will store them in the corresponding database, and finally store them in the python environment variables

[redreamality]

you can set it either for openai.
This is an approach to supporting calling openai API behind an enterprise gateway.
