\n The Innovation of RAG Technology: Why Is It Getting Attention Now? (RAG) If you’ve ever tried applying generative AI to your work, you’ve likely experienced this: the answers sound plausible, but the AI confidently presents information that doesn’t actually exist —this phenomenon is called “hallucination.” The problem is not just a simple mistake; it stems from a structural limitation where the model generates sentences “that sound convincing” based on internal probabilities. So, how can we realistically reduce these hallucinations? That’s exactly why RAG is gaining focus today. The Core Problem RAG Solves: Answering with “Evidence,” Not Just “Memory” RAG (Retrieval-Augmented Generation) is, simply put, a method where the model first retrieves relevant information from an external knowledge base, then generates answers based on that evidence . If fine-tuning is about “storing” knowledge inside the model, RAG is more like an open-book exam —consulting resou...
