Azure OpenAI for enterprise explained

Quick answer

Azure OpenAI for enterprise provides secure, scalable access to OpenAI's large language models via Azure's cloud platform using the AzureOpenAI client. It integrates with Azure Active Directory and supports enterprise-grade compliance, enabling developers to deploy gpt-4o and other models with managed authentication and usage controls.

PREREQUISITES

Python 3.8+
Azure subscription with Azure OpenAI resource
Azure OpenAI API key and endpoint
pip install openai>=1.0

Setup

Install the openai Python package and set environment variables for your Azure OpenAI API key and endpoint. Use the AzureOpenAI client to connect securely.

bash

pip install openai>=1.0

output

Collecting openai
  Downloading openai-1.x.x-py3-none-any.whl
Installing collected packages: openai
Successfully installed openai-1.x.x

Step by step

This example shows how to call the Azure OpenAI API to generate a chat completion using the gpt-4o model. Replace environment variables with your Azure OpenAI resource values.

python

import os
from openai import AzureOpenAI

client = AzureOpenAI(
    api_key=os.environ["AZURE_OPENAI_API_KEY"],
    azure_endpoint=os.environ["AZURE_OPENAI_ENDPOINT"],
    api_version="2024-02-01"
)

response = client.chat.completions.create(
    model=os.environ["AZURE_OPENAI_DEPLOYMENT"],
    messages=[{"role": "user", "content": "Explain Azure OpenAI for enterprise."}]
)
print(response.choices[0].message.content)

output

Azure OpenAI for enterprise enables secure, scalable access to OpenAI's models through Azure's cloud platform, integrating with Azure Active Directory and providing compliance features for business use.

Common variations

Use async calls with async def and await for non-blocking requests.
Stream responses by setting stream=True in chat.completions.create.
Switch models by changing the deployment name in model= parameter.

python

import asyncio
from openai import AzureOpenAI

async def main():
    client = AzureOpenAI(
        api_key=os.environ["AZURE_OPENAI_API_KEY"],
        azure_endpoint=os.environ["AZURE_OPENAI_ENDPOINT"],
        api_version="2024-02-01"
    )
    stream = await client.chat.completions.create(
        model=os.environ["AZURE_OPENAI_DEPLOYMENT"],
        messages=[{"role": "user", "content": "Stream Azure OpenAI response."}],
        stream=True
    )
    async for chunk in stream:
        print(chunk.choices[0].delta.content or "", end="", flush=True)

asyncio.run(main())

output

Azure OpenAI for enterprise provides real-time streaming of responses for interactive applications.

Troubleshooting

If you get authentication errors, verify your AZURE_OPENAI_API_KEY and AZURE_OPENAI_ENDPOINT environment variables.
Ensure your Azure OpenAI resource is deployed and the deployment name matches AZURE_OPENAI_DEPLOYMENT.
Check network connectivity and firewall rules allowing access to Azure endpoints.

✅

Key Takeaways

Use the AzureOpenAI client with your Azure API key and endpoint for enterprise-grade access.
Set environment variables for secure authentication and specify your deployment name as the model parameter.
Leverage async and streaming features for responsive, scalable applications.
Verify Azure resource deployment and credentials to avoid common connection errors.
