LLM Strategies: RAG, Fine-Tuning, and Prompt Engineering Explained

By PulseAugur Editorial · [1 sources] ·

Businesses looking to leverage large language models (LLMs) for specific tasks face a choice between prompt engineering, retrieval-augmented generation (RAG), and fine-tuning. Prompt engineering is a basic method for guiding model output without altering its core knowledge, suitable for initial prototypes. RAG enhances models by connecting them to external, up-to-date data sources, which is ideal for information that changes frequently and helps reduce hallucinations. Fine-tuning involves further training a model on a custom dataset to adjust its internal parameters for specific behaviors or knowledge, making the information part of the model itself. AI
