Day 5: Azure OpenAI | Azure in 5 Days

Provisioning Azure OpenAI

Azure OpenAI is the enterprise version of OpenAI — same models, hosted in Azure, with compliance certifications (FedRAMP, SOC2, HIPAA). Access requires approval but is generally available now.

Azure Portal Steps

# 1. Search 'Azure OpenAI' in portal
# 2. Create resource in a supported region (East US, West Europe)
# 3. Go to Azure OpenAI Studio
# 4. Deployments → Create new deployment → Select gpt-4o
# 5. Note your: endpoint URL, API key, deployment name

Python SDK

pip install openai

Call Azure OpenAI

from openai import AzureOpenAI

client = AzureOpenAI(
    azure_endpoint='https://YOUR_RESOURCE.openai.azure.com/',
    api_key='YOUR_API_KEY',
    api_version='2024-02-01'
)

response = client.chat.completions.create(
    model='gpt-4o',  # your deployment name
    messages=[
        {'role': 'system', 'content': 'You are a helpful assistant that summarizes documents.'},
        {'role': 'user', 'content': 'Summarize this in 3 bullet points: ' + document_text}
    ],
    max_tokens=500
)

Document Summarizer App

import os
from openai import AzureOpenAI

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

def summarize(text: str) -> str:
    response = client.chat.completions.create(
        model=os.environ['AZURE_DEPLOYMENT_NAME'],
        messages=[{
            'role': 'user',
            'content': f'Summarize this document in 5 bullet points:\n\n{text}'
        }],
        temperature=0.3
    )
    return response.choices[0].message.content

# Test it
with open('document.txt') as f:
    print(summarize(f.read()))

ℹ️

Azure OpenAI uses the same SDK as OpenAI — just replace the client instantiation. This means you can switch between the two with minimal code changes. Azure adds compliance, private networking (VNet integration), and enterprise SLAs.

Day 5 Summary

Azure OpenAI = same GPT-4 models, hosted in Azure, enterprise compliance included.
The Python SDK is identical to the OpenAI SDK. Just change the client instantiation.
Store credentials in environment variables. Never hardcode API keys in source code.
Azure OpenAI is the right choice for government and healthcare apps requiring FedRAMP/HIPAA.
