RAG Explained: How LLMs Access and Use Specific, Up-to-Date Data

Retrieval Augmented Generation (RAG) is a technique that addresses the limitations of Large Language Models (LLMs) in accessing and utilizing specific, up-to-date data. LLMs are trained on vast public datasets with a knowledge cutoff, meaning they cannot access information created after their training or private company data. While fine-tuning can adapt a model's style or behavior, it does not reliably store factual knowledge and requires frequent retraining as data changes. RAG, conversely, first retrieves relevant information from a data source before passing it to the LLM for generation, ensuring responses are grounded in current and specific facts without overwhelming the model's context window or incurring high costs.

IMPACT RAG enables LLMs to provide accurate, context-specific answers by grounding them in current data, overcoming hallucination and knowledge cutoff limitations.
