A recent experiment comparing retrieval-augmented generation (RAG), fine-tuning, and long-context language models found that RAG significantly outperformed the other methods. The long-context approach, despite models like Claude Sonnet 5 and Gemini 3.5 Flash offering up to 1 million tokens, proved to be approximately 24 times more expensive at scale and failed to retain information from the middle of documents. Fine-tuning was identified as the least effective method, resulting in more hallucinations than the base model. AI
IMPACT RAG is confirmed as the most cost-effective and reliable method for knowledge retrieval, potentially guiding future AI system development.
