Azure OpenAI in Azure AI Foundry Models API lifecycle

v1 API

Python v1 examples

API Key:

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.getenv("AZURE_OPENAI_API_KEY"),
    base_url="https://YOUR-RESOURCE-NAME.openai.azure.com/openai/v1/"
)

response = client.responses.create(   
  model="gpt-4.1-nano", # Replace with your model deployment name 
  input="This is a test.",
)

print(response.model_dump_json(indent=2)) 

• OpenAI() client is used instead of AzureOpenAI().
• base_url passes the Azure OpenAI endpoint and /openai/v1 is appended to the endpoint address.
• api-version is no longer a required parameter with the v1 GA API.

API Key with environment variables set for OPENAI_BASE_URL and OPENAI_API_KEY:

client = OpenAI()

Microsoft Entra ID:

from openai import OpenAI
from azure.identity import DefaultAzureCredential, get_bearer_token_provider

token_provider = get_bearer_token_provider(
    DefaultAzureCredential(), "https://cognitiveservices.azure.com/.default"
)

client = OpenAI(  
  base_url = "https://YOUR-RESOURCE-NAME.openai.azure.com/openai/v1/",  
  api_key = token_provider  
)

response = client.responses.create(
    model="gpt-4.1-nano",
    input= "This is a test" 
)

print(response.model_dump_json(indent=2)) 

• base_url passes the Azure OpenAI endpoint and /openai/v1 is appended to the endpoint address.
• api_key parameter is set to token_provider, enabling automatic retrieval and refresh of an authentication token instead of using a static API key.
