RAG vs. Fine-Tuning: Choosing the Right AI Approach for Business Needs

Retrieval-augmented generation (RAG) is generally recommended over fine-tuning for AI systems that need to answer questions based on frequently changing business information, such as documents or product data. RAG connects a model to a search system, allowing it to find relevant passages from documents and cite its sources, akin to an open-book exam. Fine-tuning is better suited for altering a model's behavior, like adhering to a specific format or tone, but is less effective for teaching facts that change and cannot provide source attribution. The article suggests starting with RAG for most business assistants and only considering fine-tuning if the core problem is the model's response rather than its knowledge base. AI
