Azure AI Foundry Models API ライフサイクルにおける Azure OpenAI

最終世代 API

import os
from openai import AzureOpenAI

client = AzureOpenAI(
    api_key=os.getenv("AZURE_OPENAI_API_KEY"),  
    api_version="2025-04-01-preview",
    azure_endpoint="https://YOUR-RESOURCE-NAME.openai.azure.com")
    )

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)) 

次世代 API

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() クライアントは、 AzureOpenAI()の代わりに使用されます。
• base_url は Azure OpenAI エンドポイントを渡し、 /openai/v1 はエンドポイント アドレスに追加されます。
• api-version は v1 GA API で必須のパラメーターではなくなりました。

• AzureOpenAI() は、 azure_ad_token_providerによって提供されるトークンの自動更新を利用するために使用されます。
• base_url は Azure OpenAI エンドポイントを渡し、 /openai/v1 はエンドポイント アドレスに追加されます。
• api_key パラメーターは fetch_azure_token()を呼び出し、静的 API キーを使用する代わりに認証トークンの自動取得と更新を有効にします。
