Conversational AI Agents Azure OpenAI: Revolutionizing Enterprise Automation

Written by Namit Jain·April 18, 2025·8 min read

Conversational AI agents Azure OpenAI are reshaping how businesses interact with data, automate tasks, and engage with customers. The Azure AI Agent Service, now in public preview following its Ignite 2024 unveiling, extends the capabilities of the Azure OpenAI Assistants API, providing enhanced tooling and paving the way for developers to build intelligent, action-oriented applications with significantly reduced custom development effort. What was once achieved with hundreds of lines of code for client-side function calling can now be streamlined to just a few using the Azure AI Agent Service, illustrating its power and efficiency.

Understanding Conversational AI Agents in Azure OpenAI

An AI Agent within Azure AI Foundry acts as a "smart" microservice, adept at answering questions (RAG), performing actions, and fully automating workflows. This is achieved through the synergy of generative AI models and tools that enable interaction with real-world data sources. The Azure AI Agent Service maintains compatibility with the Azure OpenAI Assistants wire protocol, empowering developers to utilize either OpenAI SDKs or Azure AI Foundry SDKs for agent creation and execution with minimal code.

Creating an AI Agent with Azure AI Foundry SDK

To illustrate agent creation, consider the following example using the Azure AI Foundry SDK:

agent = project_client.agents.create_agent(
    model="gpt-4o-mini",
    name="my-agent",
    instructions="You are a helpful agent",
    tools=code_interpreter.definitions,
    tool_resources=code_interpreter.resources,
)

This code snippet defines an AI Agent by specifying the model ("gpt-4o-mini"), providing instructions for task completion ("You are a helpful agent"), and equipping it with relevant tools (code interpreter).

Initiating Agent Operations

After defining the agent, initiating its operation involves creating an activity thread, essentially a conversation between agents and users. Here's how to create a thread and a message:

thread = project_client.agents.create_thread()
message = project_client.agents.create_message(
    thread_id=thread.id,
    role="user",
    content="Could you please create a bar chart for the operating profit using the following data and provide the file to me? Company A: $1.2 million, Company B: $2.5 million, Company C: $3.0 million, Company D: $1.8 million",
)

The agent then performs work on the thread by invoking a run:

run = project_client.agents.create_and_process_run(thread_id=thread.id, agent_id=agent.id)
messages = project_client.agents.list_messages(thread_id=thread.id)
print(f"Messages: {messages}")

The Azure AI Agent Service automates the tool-calling lifecycle. It runs the model with provided instructions, invokes tools as the agent calls them, and returns the results. This automation is pivotal in streamlining complex workflows.

Why Choose Azure AI Agent Service?

Compared to developing directly with the Model Inference API, the Azure AI Agent Service offers a streamlined and secure approach to building and deploying conversational AI agents. Key benefits include:

  • Automated Tool Calling: The service automates parsing tool calls, invoking tools, and handling responses, server-side.
  • Secure Data Management: Conversation state is securely managed using threads, eliminating the need for manual management.
  • Out-of-the-Box Tools: Includes file retrieval and code interpreter tools, along with data source interaction tools (Bing, Azure AI Search, Azure Functions).

Azure Agents vs. Azure OpenAI Assistants

Both services enable agent building using the same API and SDKs. However, the Azure AI Agent Service offers added benefits for enterprise environments:

  • Flexible Model Selection: Supports Azure OpenAI models, Llama 3, Mistral, and Cohere.
  • Extensive Data Integrations: Integrates with Microsoft Bing, Azure AI Search, and other APIs for relevant enterprise knowledge.
  • Enterprise-Grade Security: Ensures data privacy and compliance through secure data handling, keyless authentication, and no public egress.
  • Choice of Storage Solution: Use your own Azure Blob storage or platform-managed storage.

Getting Started

To begin, create an Azure AI Foundry hub and an Agent project in your Azure subscription. Deploy a compatible model like GPT-4o and start making API calls using the SDKs.

Azure AI Agent Service In Action

Several real-world scenarios showcase the transformative impact of conversational AI agents powered by Azure OpenAI:

1. Contoso Retail Shopping Assistant

The Contoso Retail Shopping Assistant demonstrates the capabilities of Azure AI Agent Service through a conversational AI bot. The bot facilitates:

  • REST API Integration: Users can search and place orders using Swagger definitions, enabling the AI Agent service to dynamically identify and call APIs without custom code.
  • Azure Logic Apps: Handles shipment order creation post-purchase, using manual function calling for Logic App invocation.

This application utilizes the gpt-4o-mini model and Microsoft Bot Framework. The creation of the agent involves defining tools like OpenApiTool and FunctionTool, each designed to handle specific functionalities. For instance, the create_delivery_order function triggers an Azure Logic App via an HTTP POST request to create shipment orders.

2. Zammo.ai: Modernizing Contact Centers

Zammo.ai utilizes Azure OpenAI Service to enable automated conversations directly from customer source documents and web pages. Their Azure OpenAI Accelerator allows for rapid custom proof of concepts, demonstrating the value of automated customer conversations across voice, web, and social media. Organizations can provide multi-channel support in multiple languages. This approach helps businesses modernize contact centers by automating conversations with AI search and ChatGPT. In a success story with the City of Kelowna, Zammo helped summarize complex bylaws and permitting documents, providing vital information to citizens.

3. Moveworks: Revolutionizing Employee Support

Moveworks offers a conversational AI platform that understands employee needs and provides rapid, personalized responses. Built on large language models, NLU, and machine learning, Moveworks resolves a wide array of workplace requests. Azure OpenAI Service ensures the platform adapts to changing team dynamics, without predefined scripts. The platform addresses support requests simultaneously, anticipates employee requirements, and caters to them in their native languages. By leveraging Azure OpenAI, Moveworks delivers accurate results, understanding context, correcting typos, and decoding complex utterances.

4. Typeface: Transforming Content Creation

Typeface combines the power of Microsoft Azure OpenAI Service, Azure Machine Learning, and its own Affinity AI to boost personalized content creation. The platform ingests brand information (style guidelines, images, product details), then generates a range of suggested images and texts, predefined in templates. For small businesses like Vasanti Cosmetics, Typeface enables the creation of marketing content on par with major industry players, without large staff or expensive production studios. Typeface simplifies content creation, reduces costs, and helps businesses establish a strong presence across multiple channels.
