What you'll learn

RAG systems often begin as simple, monolithic scripts, but these quickly become difficult to adapt when requirements change. In this course, Modular RAGs, you will learn how to design RAG systems that are structured into clear modules and operators. First, you will explore the three-tier architecture of modular RAG, where indexing, retrieval, and generation are separated into independent components. Next, you will see how to apply common flow patterns such as linear paths, conditional routing, branching, looping, and fusion, and see how these patterns make the system respond effectively to different types of queries. Finally, you will learn to reconfigure operators and flows to adapt the same system to new situations, demonstrating how modular design makes RAG flexible, maintainable, and ready for practical use. When you finish this course, you will have the skills and knowledge to design modular RAG applications that go beyond simple notebooks and support real project needs.
