Build AI agents that reason, retrieve, and act
AI agents can do more than generate text. They can plan, make decisions, and take actions based on the tools and data available to them. In this course, you’ll learn how to build intelligent AI agents using Haystack, an open-source framework for orchestrating large language models and external components. You’ll create a healthcare agent that answers user questions by combining up-to-date online content with structured patient records.Conntect your agents
You’ll start by using Haystack components to communicate with an LLM, then move on to creating your first agent. You’ll connect tools such as real-time web search and a SQL database query pipeline, giving the agent the ability to pull in both public and private information. You’ll also learn how to register Haystack pipelines as tools, making it easier to reuse structured workflows inside your agent.Build and extend real-world workflows
By the end of the course, you’ll have a robust agent that combines LLM reasoning with external tools and structured pipelines. You’ll understand when to use agents, when to use pipelines, and how to build flexible systems that can use both. Whether you’re building assistants, retrieval-augmented generation systems, or domain-specific tools, you’ll be ready to create production-ready AI agents with Haystack.Prerequisites

FAQs
What kind of AI agent will I build in this course?
You will build a healthcare agent capable of searching the web and querying structured patient data, using the Haystack open-source framework for LLM-based applications.
How long is this course?
The course is compact with 2 chapters, 11 exercises, and about 90 minutes of content. Most learners complete it in roughly 1 to 1.5 hours.
What makes an AI agent different from a regular chatbot?
Agents can reason, make decisions, and use external tools to take action, while regular chatbots just generate text responses. This course teaches you to build that decision-making capability.
Will I learn to debug and trace agent decisions?
Yes. Chapter 2 covers streaming callbacks for tracing agent decisions, making your agents more transparent and easier to debug.
What tools can the Haystack agent use?
You will give your agent access to web search and SQL query capabilities, transforming it from a passive text responder into an active problem solver with real-world data access.
