Search technology remains one of the major challenges in computer science, with few commercial products capable of searching effectively. Before the rise of Large Language Models (LLMs), powerful search capabilities weren't considered essential, as they didn't contribute directly to user experience. However, as the LLMs began to gain popularity, a powerful built-in retrieval system became required to apply LLMs to enterprise settings. This is also known as Retrieval-Augmented Generation (RAG)—searching internal knowledge bases for content most relevant to user queries before feeding it to the LLM for final answer generation.

As of v0.8, RAGFlow is officially entering the Agentic era, offering a comprehensive graph-based task orchestration framework on the back-end and a no-code workflow editor on the front-end. Why agentic? How does this feature differ from existing workflow orchestration systems?

The workflow of a naive RAG system can be summarized as follows: the RAG system does retrieval from a specified data source using the user query, reranks the retrieval results, appends prompts, and sends them to the LLM for final answer generation.

A naive RAG suffices in scenarios where the user's intent is evident, as the answer is included in the retrieved results and can be sent directly to the LLM. Yet, in most circumstances ambiguous user intents are the norm and demand iterative queries to generate the final answer. For instance, questions involving summarizing multiple documents require multi-step reasoning. These scenarios necessitate Agentic RAG, which involves task orchestration mechanisms during the question-answering process.

Agent and RAG complement each other. Agentic RAG, as the name suggests, is an agent-based RAG. The major distinction between an agentic RAG and a naive RAG is that agentic RAG introduces a dynamic agent orchestration mechanism, which criticizes retrievals, rewrites query according to the intent of each user query, and employs "multi-hop" reasoning to handle complex question-answering tasks.
