Building Production RAG Systems in 2026: Complete Tutorial with LangChain + Pinecone
A production-grade, end-to-end guide to building Retrieval-Augmented Generation (RAG) systems in 2026. This tutorial covers real-world architecture decisions with LangChain and Pinecone, including chunking strategies, embedding trade-offs, scaling patterns, observability, cost control, and failure modes that break RAG in production.
