Azure completions example

In this example we'll try to go over all operations needed to get completions working using the Azure endpoints.
This example focuses on completions but also touches on some other operations that are also available using the API. This example is meant to be a quick way of showing simple operations and is not meant as a tutorial.

import os
import openai

Setup

For the following sections to work properly we first have to setup some things. Let's start with the api_base and api_version. To find your api_base go to https://portal.azure.com, find your resource and then under "Resource Management" -> "Keys and Endpoints" look for the "Endpoint" value.

openai.api_version = '2023-05-15'
openai.api_base = '' # Please add your endpoint here

We next have to setup the api_type and api_key. We can either get the key from the portal or we can get it through Microsoft Active Directory Authentication. Depending on this the api_type is either azure or azure_ad.

Setup: Portal

Let's first look at getting the key from the portal. Go to https://portal.azure.com, find your resource and then under "Resource Management" -> "Keys and Endpoints" look for one of the "Keys" values.

openai.api_type = 'azure'
openai.api_key = os.environ["OPENAI_API_KEY"]

Note: In this example, we configured the library to use the Azure API by setting the variables in code. For development, consider setting the environment variables instead:

OPENAI_API_BASE
OPENAI_API_KEY
OPENAI_API_TYPE
OPENAI_API_VERSION

(Optional) Setup: Microsoft Active Directory Authentication

Let's now see how we can get a key via Microsoft Active Directory Authentication. Uncomment the following code if you want to use Active Directory Authentication instead of keys from the portal.

# from azure.identity import DefaultAzureCredential

# default_credential = DefaultAzureCredential()
# token = default_credential.get_token("https://cognitiveservices.azure.com/.default")

# openai.api_type = 'azure_ad'
# openai.api_key = token.token

A token is valid for a period of time, after which it will expire. To ensure a valid token is sent with every request, you can refresh an expiring token by hooking into requests.auth:

import typing
import time
import requests
if typing.TYPE_CHECKING:
    from azure.core.credentials import TokenCredential

class TokenRefresh(requests.auth.AuthBase):

    def __init__(self, credential: "TokenCredential", scopes: typing.List[str]) -> None:
        self.credential = credential
        self.scopes = scopes
        self.cached_token: typing.Optional[str] = None

    def __call__(self, req):
        if not self.cached_token or self.cached_token.expires_on - time.time() < 300:
            self.cached_token = self.credential.get_token(*self.scopes)
        req.headers["Authorization"] = f"Bearer {self.cached_token.token}"
        return req

session = requests.Session()
session.auth = TokenRefresh(default_credential, ["https://cognitiveservices.azure.com/.default"])

openai.requestssession = session

Deployments

In this section we are going to create a deployment using the text-davinci-002 model that we can then use to create completions.

Deployments: Create manually

Create a new deployment by going to your Resource in your portal under "Resource Management" -> "Model deployments". Select text-davinci-002 as the model.

deployment_id = '' # Fill in the deployment id from the portal here

Completions

Now let's send a sample completion to the deployment.

prompt = "The food was delicious and the waiter"
completion = openai.Completion.create(deployment_id=deployment_id,
                                     prompt=prompt, stop=".", temperature=0)
                                
print(f"{prompt}{completion['choices'][0]['text']}.")
