You have been working on chatbots for years, but suddenly your boss told you that you need to build an AI agent. At first, it sounds like the same concept with a new name, but then you do a bit of research and the confusion arises: is an agent different from a chatbot? How does it operate independently? How to build AI agents on Azure, and are you experienced enough to do it?
Yes, in the initial stages, terms like AI agents, orchestration, and multi-agent systems can feel complicated. But the good news is that you don’t have to master everything at once.
This guide gives you a practical, beginner-friendly understanding of building AI agents. It discusses the way agents actually work and how the relevant skills match the AI-103 exam syllabus.
What Are AI Agents and How Do AI Agents Work?
An AI agent is an AI-enabled tool that can do more than respond to your questions. It can understand your goals, decide the next plan of action, use different tools, and complete the task promptly. Providing more advanced services than a traditional chatbot, the agent works independently towards a goal. The idea behind using an agentic AI on Azure is to build a system that can take charge and automate business processes.
For example:
If you ask a chatbot to find out some good hotels in Goa, you will get a proper list (but that’s all).
Whereas, the AI agent might take a step further and ask about your budget, travel dates, and locality preferences to search for relevant options.
But even today, professionals use terms like AI agents, AI applications, and AI assistants interchangeably. Sure, they might overlap in practice; each serves a different role.
AI Agent vs AI Assistant vs AI Application: Key Differences
Let’s understand how the conversational AI agents differ from AI applications and assistants:
- AI agent: The agentic AI is goal-oriented and reasons through a task, uses tools, accesses information, and takes multiple steps to achieve an outcome.
- AI application: This software application uses AI for a specific function, such as analysing images or generating content.
- AI assistant: An AI system helps a user with questions or tasks, usually through a conversational interface. Some of the common tools are ChatGPT and Alexa.
However, the lines can sometimes be blurred. An AI agent can be a part of the application, or Alexa might show agent-like abilities to complete tasks. The important thing is to understand how these concepts work both individually and as a whole.
How to Build AI Agents on Azure Step by Step
Once you are familiar with how an AI agent works differently from a traditional chatbot, the next step is building the AI agent tutorial.
You don’t have to start developing complex AI agents straightaway, especially if you are new. Start by creating the agent for a basic task and give the right set of commands and information. You can gradually add more features to it to make the agent more capable for business use.
1. Build Your First AI Agent
Start by building an AI agent on the Azure AI Foundry according to your goal. For example, you can create an agent to answer every travel-related question for fellow adventurers or help hospitality professionals find information from a specific group of references.
At this point, your focus should be on defining the purpose and feeding the right set of instructions to the agent so it can do exactly what you want it to.
2. Configure Azure AI Agent Instructions and Tools
Once successfully built, you can improve the capabilities with Azure AI agent tools and a better set of instructions. This stage is where your knowledge of prompt engineering basics matters the most. You should explain the agent’s role and how it should respond to different customer queries. Tools let the agent do things beyond giving text responses, such as getting information, using an API, or connecting to another service.
So, the AI agent tool becomes more useful and can independently determine which tool should be used to fulfil each user request.
3. Connect Azure AI Agents to Data and Knowledge Sources
An agentic AI needs to access relevant information to answer questions based on your business-specific data. You can connect it to documents, databases, knowledge sources, or other information sources.
When you improve the capabilities of your conversational AI agents, you can combine them with multiple tools and orchestration logic. However, beginners should first understand how to build the agent and give it instructions and tools to generate accurate responses and solutions.
What Are the Prerequisites for Building AI Agents on Azure?
You do not have to be an expert when you learn the AI agent development process. But it is important that you are comfortable working with Python, generative AI, prompt engineering, and Azure. These skills give you an understanding of how to build agents and how various Azure services work together.
Below are some of the key skills expected when you are building the Azure AI agent development roadmap:
1. Python Skills for Azure AI Agent Development
Python is one of the first programming languages that you should learn when building an agentic AI application and working on Azure. After the training, you should have expertise in variables, functions, loops, libraries, and handling data.
You may also need to use APIs and SDKs to extract data or perform different tasks. An API lets one application connect to another, while an SDK provides the necessary tools so that you can easily work with a particular service or platform.
2. Generative AI and LLM Skills for Azure AI Agents
Another prerequisite is to focus on generative AI and LLMs when working with Azure OpenAI integration. You do not necessarily need to understand the maths behind AI models but should know the role of an LLM and how it operates as per the instructions and information it receives.
It is equally beneficial to figure out which your AI model might provide incorrect information at times.
3. Prompt Engineering for AI Agents on Azure
An agent only behaves the way you guide it to. So, your prompting skills should be on point, making sure that you do not end up giving the model unclear instructions. It can significantly affect how users interact with the agentic AI model.
For example, you cannot just inform the agent to help customers. You must specify its role, the type of questions it should handle, the information it can use, and how it should respond. It helps the agent become more consistent and adaptive with its responses.
4. Azure Skills Required for AI Agent Development
An understanding of Azure resources and how its services work can help you navigate the services used to build and deploy AI applications.
Even if you are unsure of every Azure service in the beginning, there’s no need to worry. This is where the AI-103 certification comes in. It builds your skills and validates your expertise in developing AI applications.
But from where do you begin preparing for the certification in a way that it simultaneously teaches you how to build an AI agent?
