From Chat Demos to Enterprise: Engineering Production-Ready RAG Systems

RAG systems have matured beyond proof-of-concept demos, but most fail in production due to poor chunking, weak retrieval, and lack of evaluation frameworks. This tutorial directly addresses these challenges with a modern tech stack—LangChain, vector databases, and reranking models—providing practical code examples and best practices. Developers can now implement reliable document-based AI systems that actually scale in enterprise environments without hallucinations or cost overruns.
