Key Points

  • Naive RAG answers in a single step by retrieving top-matching documents via similarity search and directly injecting the retrieved chunks into the prompt.
  • The article explains that Naive RAG has limitations such as lacking planning, structured filtering (e.g., price or ratings), validation/re-ranking, and relying entirely on the first retrieval results.
  • Agentic RAG improves on this by using an agent that understands intent, decomposes the task into sub-tasks, and performs multiple retrieval cycles when needed.
  • Agentic RAG can search across multiple vector collections, aggregate and re-rank results with constraints, and then synthesize a structured final answer.
  • Overall, the article argues that Agentic RAG is more accurate, adaptable, and effective for complex real-world information access problems due to iterative reasoning and validation.
