Azure OpenAI Models

Advanced Language Models

Advanced language models in Azure OpenAI excel in understanding and generating complex natural language. They are designed for applications needing deep reasoning and contextual awareness. A few of the prominent models are

• GPT-4o & GPT-4o Mini : Latest models with sophisticated reasoning and multimodal abilities.
• GPT-4 Series : Powerful models for complex language understanding and generation.
• GPT-3.5-Turbo : Efficient models for a wide range of natural language tasks.

Specialized Models

These models have been specifically designed for certain tasks: generating images, speech-to-text capabilities, and more precise similarity analysis. They further support the language models because they are multimodal and domain-specific. The most specialized models in the list include:

• Embeddings : Converts text into numerical vectors for advanced similarity analysis.
• DALL-E : Generates original images from text descriptions.
• Whisper : Transcribes and translates speech to text.
• Text-to-Speech : Synthesizes spoken language from text (currently in preview).

Chat Integration with Azure OpenAI Service

This section will guide you step-by-step to authenticate and integrate Azure OpenAI in your project.

Step 1: Set Up Your Project

1. Initialize a new Python project Open your favorite development environment. We recommend Visual Studio Code.
2. Create and configure your project

• Create a new folder for your project, and open it in the editor.
• Initialize a Python virtual environment:

     python -m venv venv
     source venv/bin/activate # On Windows: venv\Scripts\activate
     pip install --upgrade pip

1. Install required packages

pip install python-dotenv openai azure-identity azure-keyvault-secrets

1. Set up environment variables

• Create a .env file in your project folder.
• Add the following environment variables:

AZURE_OPENAI_ENDPOINT=<Your Azure OpenAI endpoint>
AZURE_OPENAI_API_KEY=<Your API key> # Omit this if using Key Vault
AZURE_KEY_VAULT_URL=https://<Your-Key-Vault-Name>.vault.azure.net/

Step 2: Create an Azure OpenAI Service

1. Log in to the Azure Portal.
2. Deploy the Azure OpenAI service:
   • Search for Azure OpenAI Service and click Create.
   • Select your subscription, resource group, and region, and deploy the service.
3. Copy endpoint and keys:
   • Navigate to the Keys and Endpoint tab in your Azure OpenAI Service.
   • Copy the Endpoint and Key for later use.

Step 3: (Optional) Set Up Azure Key Vault

For added security, use Azure Key Vault to store your API keys.

1. Create a Key Vault
   1. Search for Azure Key Vault in the Azure Portal and click Create.
2. Add a new secret
   • Name: OpenAIAPIKey
   • Value: Paste your Azure OpenAI API key.
3. Use the following code to retrieve the key from Key Vault:

from azure.identity import DefaultAzureCredential
from azure.keyvault.secrets import SecretClient

# Use Azure managed credentials
credential = DefaultAzureCredential()
key_vault_url = "https://your-keyvault.vault.azure.net/"
secret_client = SecretClient(vault_url=key_vault_url, credential=credential)

# Retrieve OpenAI credentials securely
openai_key = secret_client.get_secret("OpenAIAPIKey")

Step 4: Comprehensive Chat Implementation

Use the following code to implement the chat application:

from typing import List, Dict, Optional
import os
from dotenv import load_dotenv
from openai import AzureOpenAI
import logging
from logging.handlers import RotatingFileHandler

class AzureOpenAIChat:
    def __init__ (
