Loop Engineering for RAG Generation: An LLM Cascade from a Cheap Local Model Up to a Hosted Flagship
Loop Engineering presents a compelling approach to Retrieval-Augmented Generation (RAG) with its LLM Cascade, detailed in "Loop Engineering for RAG Generation." This innovative strategy sequences language models, starting with cost-effective local models and scaling up to a hosted flagship, optimizing both expense and accuracy. The research validates this cascade through rigorous testing—a sweep of twenty local models compared against a flagship—highlighting two key benefits: cost efficiency and a robust validation loop.
