How to do function calling using Azure OpenAI

Question

Here is my code

response = openai.ChatCompletion.create(
    engine="XXX", # The deployment name you chose when you deployed the ChatGPT or GPT-4 model.
    messages=[
        {"role": "system", "content": "Assistant is a large language model trained by OpenAI."},
        {"role": "user", "content": "Calculate the circumference of circle with radius 5?"}
    ],
    functions=[{'name': 'circumference_calc', 'description': 'Calculate the circumference of circle given the radius', 'parameters': {'type': 'object', 'properties': {'radius': {'description': 'The radius of the circle', 'type': 'number'}}}, 'required': ['radius']}]
)

Results in :

InvalidRequestError: Unrecognized request argument supplied: functions

UPDATE (13. July 2023): Azure now supports function calling in API version 2023-07-01-preview on these models:

• gpt-4-0613
• gpt-4-32k-0613
• gpt-35-turbo-0613 (thanks Joel)
• gpt-35-turbo-16k-0613

---

Previous answer:

Only version gpt-3.5-turbo-0613 and gpt-4-0613 has function calling (ref), and Azure OpenAI Services only supports these for now (ref):

• gpt-3.5-turbo-0301
• gpt-4-0314
• gpt-4-32k-0314

Hopefully, the Azure OpenAI Service team will support the 0613 version soon.

UPDATE (3. July 2023): Even though 0613 is out now, it seems like they still don't support functions as a parameter, as some others have pointed out here. I have tested using 2023-06-01-preview, which is supposed to be the newest API interface (according to these specs) with no luck.. I also found that version 2023-07-01-preview is working too, now, but no luck there either. (This has now changed. See update on the top^)

Answer 2

This has started working now. Make sure that your model version is 0613. I have tested with gpt-35-turbo.

import openai

openai.api_type = "azure"
openai.api_key = "XXX"
openai.api_base = "https://XXXX.openai.azure.com/"
openai.api_version = "2023-07-01-preview"

response = openai.ChatCompletion.create(
    engine="XXX",
    messages=[{"role": "user", "content": "what is current date?"}],
    functions=[
        {
            "name": "get_current_date",
            "description": "Get the current date in YYYY-MM-DD format",
            "parameters": {"type": "object", "properties": {}, "required": []},
        }
    ],
)
print(response["choices"][0])

Response:

<OpenAIObject at 0x10d2c1790> JSON: {
  "index": 0,
  "finish_reason": "function_call",
  "message": {
    "role": "assistant",

      "arguments": "{}"
    }
  },
  "content_filter_results": {}
}
