This article argues that Retrieval-Augmented Generation (RAG) systems are not inherently flawed, but rather that their production failures stem from poor engineering practices. It highlights a real-world scenario where a banking chatbot failed due to issues like small chunk sizes, mismatched embedding models, and inadequate reranking. The piece offers a playbook for optimizing RAG pipelines across various layers, from chunking to evaluation, to achieve better performance, lower costs, and increased trustworthiness in production environments.
