Large Language Models (LLMs) have revolutionized our interaction with information. However, their dependence on internal knowledge alone can limit the accuracy and depth of their responses, especially for complex queries. Retrieval-Augmented Generation (RAG) addresses this limitation by enabling LLMs to access and process information from external sources, resulting in more grounded and informative answers.
While standard RAG excels at handling simple queries across a few documents, agentic RAG takes it a step further and emerges as a formidable solution for question answering. The key differentiator of agentic RAG is the introduction of AI agents. These agents act as autonomous decision-makers, analyzing initial findings and strategically selecting the most effective tools for further data retrieval. This multi-step reasoning capability empowers agentic RAG to tackle intricate research tasks, such as summarizing, comparing information across multiple documents, and even formulating follow-up questions – all in an organized and efficient manner. This newfound agency transforms the LLM from a passive responder to an active investigator, capable of delving deep into complex information and delivering comprehensive, well-reasoned answers. agentic RAG holds immense potential for applications such as research, data analysis, and knowledge exploration.

It leverages the collaborative intelligence of diverse agents to conquer intricate knowledge hurdles. Through its capabilities for planning, reasoning, employing tools, and ongoing learning, agentic RAG transforms the pursuit of comprehensive and accurate knowledge acquisition.
By comparing agentic RAG and traditional RAG, we can gain valuable insights into the evolution of retrieval-augmented generation systems. In this article, we will focus on the key features that distinguish agentic RAG from its traditional counterpart, highlighting the advancements it brings.
The distinct capabilities of agentic RAG highlight its potential to revolutionize information retrieval. By enabling AI systems to actively interact with and explore intricate environments, agentic RAG empowers these systems to engage more effectively with their surroundings. This leads to improved decision-making and efficient task completion through enhanced information retrieval capabilities.
Within a RAG framework, agents display diverse usage patterns tailored to specific tasks and objectives. These patterns highlight the agents’ adaptability and versatility when interacting with RAG systems. Key usage patterns of agents in an RAG context include:
Agents can leverage existing RAG pipelines as tools to accomplish specific tasks or produce outputs. By utilizing these established pipelines, agents can simplify their operations and benefit from the capabilities inherent in the RAG framework.
Agents can operate autonomously as RAG tools within the framework. This autonomy allows agents to generate responses independently based on input queries, without relying on external tools or pipelines.
Agents can retrieve relevant tools from the RAG system, such as a vector index, based on the context provided by a query at query time. This tool retrieval enables agents to adapt their actions according to the unique requirements of each query.
Agents can analyze input queries and select appropriate tools from a predefined set of existing tools within the RAG system. This query planning enables agents to optimize tool selection based on the query requirements and desired outcomes.
When the RAG system offers a wide range of tools, agents can assist in selecting the most suitable one from the candidate tools retrieved based on the query. This selection process ensures that the chosen tool closely aligns with the query context and objectives.
Within a RAG framework, agents can leverage these usage patterns to execute various tasks effectively. By combining and customizing these patterns, complex RAG applications can be tailored to meet specific use cases and requirements. Harnessing these patterns enhances the overall efficiency and effectiveness of the system, enabling agents to accomplish their tasks seamlessly.
RAG agents can be classified into distinct categories based on their functional capabilities. This spectrum of capabilities ranges from simple to complex, resulting in varying costs and latency. These agents can fulfill diverse roles such as routing, planning one-time queries, employing tools, utilizing ReAct (Reason + Act) methodology, and coordinating dynamic planning and execution.
The routing agent makes use of a Large Language Model (LLM) to choose the best downstream retrieval augmented generation RAG pipeline. This decision-making process involves agentic reasoning, where the LLM analyzes the input query. This allows it to select the most appropriate RAG pipeline. This process exemplifies the core and basic form of agentic reasoning.
When determining the best routing for a query, two options arise: using a summarization retrieval augmented generation pipeline or a question-answering RAG pipeline. The agent analyzes the input query to ascertain whether it should be directed to the summary query engine or the vector query engine, both of which are configured as tools.
In query planning, a complex query is decomposed into smaller, parallelizable subqueries. These subqueries are then executed across various RAG pipelines, each utilizing different data sources. The responses obtained from these pipelines are amalgamated to form the final comprehensive response. This process involves breaking down the query, executing the subqueries across suitable pipelines, and synthesizing the results into a cohesive response.

In a standard Retrieval-Augmented Generation framework, a query is submitted to retrieve the most relevant documents that align semantically with the query. However, there are situations where additional information is necessary from external sources, such as APIs, SQL databases, or applications with API interfaces. This additional data acts as contextual input to enrich the initial query before it undergoes processing by the Large Language Model (LLM). In such scenarios, the agent can also leverage a RAG model.
ReAct: Integrating Reasoning and Actions with LLMs
Elevating to a more advanced level requires the incorporation of reasoning and actions executed iteratively for complex queries. This essentially consolidates routing, query planning, and tool utilization into a single entity. A ReAct agent capably handles sequential, multi-part queries while maintaining an in-memory state. The process unfolds as follows:
The most widely adopted agent is currently ReAct, but there is a growing need to handle more complex user intents. As more agents are deployed in production environments, there is an increasing demand for enhanced reliability, observability, parallelization, control, and separation of concerns. This necessitates long-term planning, execution insight, efficiency optimization, and latency reduction.
At their core, these efforts aim to separate high-level planning from short-term execution. The rationale behind such agents involves:
This necessitates both a planner and an executor. The planner typically utilizes a large language model (LLM) to craft a step-by-step plan based on the user query. The executor then executes each step, identifying the tools needed to accomplish the tasks outlined in the plan. This iterative process continues until the entire plan is executed, resulting in the presentation of the final response.
Constructing an agentic Retrieval-Augmented Generation necessitates specialized frameworks and tools that streamline the creation and coordination of multiple agents. Although building such a system from the ground up can be intricate, there are several existing alternatives that can simplify the implementation process.
