Azure OpenAI with AAD Auth

This guide will show you how to use the Azure OpenAI client with Azure Active Directory (AAD) authentication.

The identity used must be assigned the Cognitive Services OpenAI User role.

Install Azure Identity client

The Azure identity client is used to authenticate with Azure Active Directory.

pip install azure-identity

Using the Model Client

from autogen_ext.models.openai import AzureOpenAIChatCompletionClient
from azure.identity import DefaultAzureCredential, get_bearer_token_provider

# Create the token provider
token_provider = get_bearer_token_provider(
    DefaultAzureCredential(), "https://cognitiveservices.azure.com/.default"
)

client = AzureOpenAIChatCompletionClient(
    azure_deployment="{your-azure-deployment}",
    model="{model-name, such as gpt-4o}",
    api_version="2024-02-01",
    azure_endpoint="https://{your-custom-endpoint}.openai.azure.com/",
    azure_ad_token_provider=token_provider,
)
