RAG: Retrieval Augmented Generation – The Architecture of Reliable AI

In this primer, we systematically introduce the concepts and architecture of RAG. We cover both theoretical foundations and practical implementation aspects such as chunking, embedding, and vector databases. Additionally, we share our practical experience from real-world projects. This is designed for software architects and developers seeking a compact yet thorough introduction to the topic who want to evaluate the use of RAG in their own organization.
