Standard RAG is a "one-shot" process: search, retrieve, generate. "Agentic RAG" is an iterative process where the AI acts as a researcher, deciding for itself if the retrieved information is enough to answer the question.
In Agentic RAG, if the first search results are poor, the AI doesn't just hallucinate an answer. Instead, it recognizes the failure and tries a different search query or a different tool. It can cross-reference multiple documents and "verify" facts before providing a final response. This leads to much higher accuracy, especially for complex questions where the answer is spread across different sources.
When faced with an ambiguous query, an Agentic RAG system can ask follow-up questions or perform multiple "exploratory" searches to narrow down the user's intent. This proactive behavior makes the AI feel much more like a human researcher than a simple search engine, resulting in a significantly more helpful and trust-worthy assistant.
