Paperback. Condizione: new. Paperback. Move Beyond "Hello World" Tutorials. Stop Hallucinations, Fix Wrong Retrieval, and Build Production-Grade AI Systems That Don't Break at Scale.Have you ever followed a basic AI tutorial, watched a naive Retrieval-Augmented Generation (RAG) system work flawlessly on ten sample documents, and shipped it to production with absolute confidence-only to watch it completely fall apart three weeks later under the weight of ten thousand real-world files?When retrieval fails, answers hallucinate, and users get frustrated, most developers immediately blame the Large Language Model. But the brutal truth is that 90% of RAG failures are retrieval failures, not generation failures. The LLM cannot synthesize a correct answer if you feed it the wrong context.In RAG with LangChain & Agentic AI: LangChain Explained So Simply a 5-Year-Old Could Build An Autonomous AI Agent, software engineer and AI systems architect John Cutts delivers the definitive 2026 operational playbook for transitioning from fragile prototypes to resilient, enterprise-grade AI infrastructure. This book completely eliminates the "chunk-and-pray" methodology and replaces it with deterministic, self-correcting engineering patterns.What You Will Master Inside This Complete Playbook: The Core RAG Architecture: Master the three pillars-Indexing, Retrieval, and Generation-using Python, LangChain, and ChromaDB to separate knowledge from frozen LLM reasoning data.The Art of Chunking: Learn why chunking is architecture, not pre-processing. Navigate the chunking decision framework to deploy Fixed, Recursive, and Semantic splitters that preserve critical data context.The 5 Production Failure Modes: Acquire a practical debugging playbook to diagnose bad chunking, poor prompt engineering, wrong embedding models, insufficient context ($k$ too small), and separate retrieval testing layers.Anthropic's Contextual Retrieval: Implement cutting-edge chunk enrichment strategies that reduce retrieval failures by up to 67% by combining LLM-generated context with cross-encoder reranking.Agentic RAG with LangGraph: Replace static pipelines with stateful, self-correcting autonomous decision-making loops that grade documents, rewrite failing queries, and execute graceful fallbacks.Graph RAG & Multi-Hop Reasoning: Transcend standard vector search boundaries using Microsoft's GraphRAG framework to extract complex networks of entities and relationships for multi-document insights.Multimodal RAG with ColPali: Stop stripping out critical corporate assets. Use vision-language models to embed page layouts, charts, schematics, and complex tables directly as visual images.The Production Runbook: Gain complete system observability using LangSmith tracing, deploy massive cost-management tactics (saving up to 25x vs long-context windows), and structure hybrid text-vision pipelines."The gap between 'it works in the demo' and 'it works in production' is exactly as wide as the gap between naive RAG and the system you have learned to build in this book." - John CuttsWhether you are a software engineer, data scientist, or technical builder, this book skips the theoretical fluff and delivers raw, working code derived from hard-won production experience.
