The article 'What is Agentic RAG? Building Agents with Qdrant' by Kacper Łukawski explores the integration of Retrieval Augmented Generation (RAG) with AI agents, a concept referred to as Agentic RAG. Traditional RAG systems follow a linear process: receive a query, retrieve relevant documents, and generate a response, which can fail if the context does not provide enough information. In contrast, AI agents have more freedom to act and can take multiple non-linear steps to achieve a goal. The article defines an agent as an application that uses a Large Language Model (LLM) and tools to interact with the external world, with the LLM acting as a decision-maker. Agentic RAG systems break the linear flow of standard RAG and allow agents to decide when and how to use external knowledge sources. The article discusses various tools that can be used in such systems, such as querying a vector database, query expansion, extracting filters, and quality judgment. It also highlights the importance of multi-agent systems and the role of human-in-the-loop interactions. The article further explores different frameworks for building Agentic RAG systems, including LangGraph, CrewAI, and AutoGen. LangGraph, developed by the LangChain team, is a graph-based framework that allows for cyclic workflows and supports multi-agent systems. CrewAI focuses on multi-agent systems and provides a rich set of tools for integrating RAG with other functionalities. AutoGen emphasizes multi-agent architectures and includes features like code executors and tool functions. The article concludes by discussing the applicability of Agentic RAG in different scenarios, noting that while it may not be suitable for all use cases due to the cost and latency associated with LLM usage, it can be valuable in areas like customer support where users are willing to wait for better answers.
