RAG Agent vs. Agentic RAG: A Comprehensive Comparison

By Akshay Patkar

Overview

The evolution of AI has ushered in sophisticated methods for information retrieval and generation. Two prominent paradigms in this domain are RAG Agent and Agentic RAG. While both aim to enhance the capabilities of language models by integrating external knowledge and information retrieval mechanisms, they differ fundamentally in their architecture, autonomy, and application. This analysis delves into their distinctions, strengths, and ideal use cases.
