Retrieval-Augmented Generation (RAG) was introduced to address limitations in large language models (LLMs) such as knowledge cutoffs, hallucination, lack of source attribution, and inability to access private data. These issues stem from LLMs being trained on static data, meaning their knowledge is frozen after training. While LLMs can perform in-context learning by processing new information within a prompt, practical constraints like context window limits, cost, latency, and accuracy degradation in long prompts make this approach insufficient for comprehensive knowledge integration.

IMPACT RAG provides a method to overcome LLM limitations by integrating external knowledge, enabling more accurate and context-aware responses.
