Instead of relying solely on a foundation model's parametric memory (which is frozen at training time and prone to confident confabulation), RAG systems ground the model's responses in authoritative, up-to-date enterprise documents retrieved at query time. In theory, this architecture is elegant and effective. In practice, enterprise RAG deplo
