Invalid Purpose Error when Using file.create in OpenAI Azure

I’m attempting to use file.create to feed a CSV file of data to an assistant I’m creating. The idea is that the assistant would leverage the data provided for analysis. I’ve been unable to do this both via the Python API and the openai CLI due to HTTP 400 Error response codes, Error code: 400 - {‘error’: {‘code’: ‘invalidPayload’, ‘message’: ‘Invalid value for purpose.’}}.

Example of how I’m running cli:

$ openai -k “$OPENAI_API_KEY” -t azure --api-version “2023-07-01-preview” --azure-endpoint hxxps:// api files.create -f …\results.csv -p answers

Example of Python code:

import coloredlogs
import csv
import http.client
import logging
import os
import sys
import time
from openai import AzureOpenAI
from openai._exceptions import BadRequestError, AuthenticationError, PermissionDeniedError, NotFoundError
from openai._exceptions import ConflictError, UnprocessableEntityError, RateLimitError, InternalServerError
from openai._exceptions import APIConnectionError, APIStatusError
from pathlib import Path

http.client.HTTPConnection.debuglevel = 1
requests_log = logging.getLogger(“http.client”)
coloredlogs.install(level=“DEBUG”, logger=requests_log)

client = AzureOpenAI(
api_version = “2023-12-01-preview”,
azure_endpoint = “hxxps://”,
api_key = os.getenv(“OPENAI_API_KEY”)

def set_assistant_file():
file = client.files.create(
return file
except APIConnectionError as err:
print(f"APIConnectionError: {str(err)}“)
except APIStatusError as err:
print(f"APIStatusError: {str(err)}”)
except BadRequestError as err:
print(f"BadRequestError: {str(err)}“)
except TypeError as err:
print(f"TypeError: {str(err)}”)

if name == “main”:

Output is as follows:

Hmm, it would seem that this being a beta API feature, it’s not available currently in OpenAI Azure APIs: Looking there, I see that file upload is available, but only for fine-tune purpose and only for jsonl files. Can anyone in community point me to where I would need to go to request access to the beta API version that provides ability to create assistants based upon uploaded files?

I am not able to replicate the file upload using Azure OpenAI. The code:
file = client.files.create(file=open(“…/…/data/input.pdf”, “rb”), purpose=“assistants”)
works in openAI but fails to work under AzureOpenAI. Like the previous comment, I am using it as an upload for retrieval not for finetuning.

It seems that the assistants purpose should only be recognized in versions 2024-02-15-preview or later. However, even when using these versions I can’t complete an upload at the thread level. Has anyone figured this out?

Figured it out, for anyone that finds this. For me it was a region issue. I manage several different regions in my application so the region must be Assistants compatible: Azure OpenAI Service models - Azure OpenAI | Microsoft Learn
