RAG systems fail before the model: developers urged to fix pipeline

Retrieval-augmented generation (RAG) systems often fail due to issues earlier in the pipeline, rather than the language model itself. Common problems include poorly parsed documents, incorrect chunking of information, and failure to retrieve relevant passages. To address these failures, developers are advised to implement an evaluation loop that involves creating a set of golden questions, modifying one stage of the RAG process at a time, and scoring retrieval and answers separately before releasing any changes. AI

IMPACT Developers can improve RAG system accuracy by focusing on data preparation and retrieval rather than solely on the LLM.
