Hi @QuarkBS2, I believe that there is more refactoring to the codebase required to bump the openai version to the updated functiond.

Hi, you mean specifying the OpenAI version into the requirements.txt file?

Hi, thanks for providing me with more context.
I have checked the documentation, and as you can see here: Create OpenAPI Reference
The code is still pretty much the same to what is already in the current main branch, the main difference is the function with which you call the endpoint, but they do work the same way.
And is the same thing with the Error handling as you can check here: API error handling
I could definitely try to optimize some pieces of the code, or add new exceptions, but I'm not sure if that would be what you expect or if it would be out of the scope for this issue.
