Building Retrieval-Augmented Agents with DSPy: Declarative RAG Systems with Python and LLMs (Design, Optimize, and Deploy Modular RAG Agents with DSPy, Vector Databases and LLM Toolchains)

Unlock the full potential of Retrieval-Augmented Generation (RAG) with Building Retrieval-Augmented Agents with DSPy, the definitive guide to designing modular, declarative, and self-improving AI systems using Python and large language models (LLMs). Whether you're an AI developer, machine learning engineer, backend architect, or NLP researcher, this book delivers a hands-on, end-to-end approach to constructing intelligent agents using the powerful DSPy framework. You'll learn how to build robust RAG pipelines that seamlessly integrate vector search, document chunking, tool calling, memory handling, and modular LLM orchestration-while maintaining full control over optimization and traceability. Written by Roberto Pizzlo, a leading voice in the field of modern AI systems, this book is your launchpad into scalable, production-ready agentic workflows. With concise explanations, up-to-date DSPy examples, and best practices drawn from real-world deployments, this guide equips you to build agents that reason, retrieve, revise, and respond with precision. Inside You'll Learn: How to construct declarative RAG pipelines using DSPy's signature-driven programming Techniques for chunking, embedding, indexing, and hybrid retrieval using FAISS, Qdrant, and Weaviate How to integrate OpenAI, Claude, Cohere, or local LLMs via DSPy modules Optimizing agents using MIPROv2, BootstrapFewShot, and assertion-based correction loops Tool-augmented workflows combining search, calculators, summarizers, and code interpreters Real-world case studies on building enterprise-grade knowledge bots Deployment strategies with FastAPI, Docker, and local embedding models via Ollama Future directions in modular RAG, memory-augmented agents, and self-adaptive pipelines Why This Book?Unlike abstract theory-heavy texts, this guide focuses on practical implementation, real-world design patterns, and scalable agent infrastructure. It's built for the realities of 2024 and beyond, where precision, observability, and modular design are essential for AI production systems. If you're working with DSPy, Python, RAG, LLMs, retrievers, vector search, or frameworks like LangChain, LlamaIndex, or AutoGen, this book is a must-have resource in your AI development toolkit.
