RAG vs. Fine-Tuning: Choosing the Right LLM Strategy Based on Failure Type

By PulseAugur Editorial · [2 sources] ·

This article explores the strategic choices between retrieval-augmented generation (RAG) and fine-tuning for large language models, suggesting a layered approach based on the type of failure encountered. Prompting is presented as the initial, least expensive layer, followed by RAG for knowledge gaps and fine-tuning for behavioral adjustments. Agentic search is recommended only when a single query cannot yield the answer, emphasizing that each method addresses distinct limitations. AI

IMPACT Provides guidance for AI developers on selecting appropriate techniques like RAG, fine-tuning, and prompting to address specific model failures.

RANK_REASON The article provides an analytical comparison and strategic guidance on different LLM techniques, rather than announcing a new release or event.

    RAG vs fine-tuning vs agentic search, and when to use each

    <p>Choose between RAG and fine-tuning by the failure you can see. Use retrieval when the model is missing a fact, and fine-tuning when the facts are right and a specialist says the output reads wrong. Use agentic search, also called agentic RAG, only when no single query can find…
