Retrieval Augmented Generation, The Seminal Papers

Retrieval Augmented Generation (RAG) is a standard process for grounding LLM prompts in user-specified content rather than relying only on a model’s training data. RAG has grown from a simple prompt engineering workflow into a sophisticated set of data analysis, storage, and retrieval techniques. Retrieval Augmented Generation, The Seminal Papers explores 12 foundational research papers that explain why RAG works, how it’s built, and what makes it different from other approaches.

This authoritative book explores the papers that define RAG’s enduring architectural pattern. Author Ben Auffarth traces RAG’s evolution from the foundational breakthroughs of REALM, RAG, and DPR to advanced architectures like FiD and Atlas. Designed to be both interesting and practical, Retrieval Augmented Generation, The Seminal Papers illuminates techniques that empower systems to retrieve intelligently, evaluate themselves, and recover from errors. Over forty code samples, architectural diagrams, and industry case studies make each concept easy to understand. As you master the patterns behind RAG, you’ll better understand tradeoffs, diagnose failures, and effectively evaluate and improve your own RAG implementations.
