openai.BadRequestError: Unrecognized request argument supplied: response_format

Question

Following Python example in Learn How to use JSON docs, returns the following error -

openai.BadRequestError: Error code: 400 - {'error': {'message': 'Unrecognized request argument supplied: response_format', 'type': 'invalid_request_error', 'param': None, 'code': None}}

It seems like the argument does get recognised because when changing "json_object" to "asd", API returns a different kind of error -

openai.BadRequestError: Error code: 400 - {'error': {'message': "'asd' is not one of ['json_object', 'text'] - 'response_format.type'", 'type': 'invalid_request_error', 'param': None, 'code': None}}

Is this a potential bug or documentation is incorrect?

Answer 1

Hi @Ruslan Levond Welcome to Microsoft Q&A! Thanks for posting the question. I have tried the Python example code you are referring to and got the results correctly with GPT-4-1106 preview model version. (see screenshot below) Which model you are trying to use? Also, which openai package version you are using? I have tried with openai version 1.9.0.

Thanks

Answer 2

Thanks Saurabh, I was using the wrong deployment which had the old version of the model.
