RAG with Python Cookbook

Retrieval-augmented generation (RAG) has emerged as a critical technology in an era where organizations rely on accurate, context-aware AI systems. As LLMs expand across industries, RAG enables teams to build solutions that are more trustworthy, factual, and aligned with real-world knowledge, making it an essential skill for modern engineers, analysts, data scientists, and software developers.

This book provides a comprehensive, hands-on guide to master RAG with Python. It begins with the foundations of embeddings, vector databases, and retrieval pipelines, moving into prompt engineering, hybrid search strategies, and prompt engineering strategies, like chain-of-thought and MapReduce to enhance response quality. It then covers evaluation, optimization, and agentic workflows. Each chapter delivers clear explanations that help you preprocess data, build scalable pipelines, integrate LLMs, automate reasoning, and deploy end-to-end RAG systems tailored to real-world use cases.

By the end of this book, readers will be able to design, implement, and optimize robust RAG solutions with confidence. They will gain the skills to build retrieval-aware applications, enhance enterprise workflows, develop intelligent agents, and apply industry-proven techniques that directly strengthen their professional capabilities.
