LLM Adaptation: Prompting, RAG, and Fine-tuning Explained

Choosing between fine-tuning, retrieval-augmented generation (RAG), and prompting for LLM adaptation involves understanding their distinct roles. Prompting is the fastest and cheapest method, suitable for steering existing knowledge. RAG is ideal for providing models with current or private factual knowledge without altering their weights. Fine-tuning is reserved for changing a model's inherent behavior, such as tone or format, by updating its weights. AI

IMPACT Clarifies the distinct use cases for prompting, RAG, and fine-tuning, guiding developers to choose the most cost-effective method for their specific LLM adaptation needs.
