Retrieval-Augmented Generation (RAG): Architecture, Mechanisms, and Core Advantages

Retrieval-Augmented Generation (RAG) represents a paradigm shift in natural language processing (NLP), integrating large language models (LLMs) with dynamic information retrieval systems to produce responses that are both contextually enriched and factually grounded (Lewis et al. 2020). At its core, the RAG architecture couples a conventional generative model—one that

Generative Artificial Intelligence: Just Hype or Reality?

Gartner’s 2024 Technology Hype Cycle—which outlines the dynamics of expectations surrounding technological innovations across five distinct phases—indicates that generative AI has surpassed the peak of inflated expectations. Nevertheless, the associated hype remains persistent (see figure below), and the technology continues to hold the potential to become truly
