- 5. 5/11 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: Employing Pre-existing RAG Pipelines as Tools 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. Functioning Independently as RAG Tools: 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. Dynamic Tool Retrieval Based on Query Context: 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. Query Planning Across Existing Tools: 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. Selecting Tools from the Candidate Pool: 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 Categorized by Functionality: 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. 1. Routing Agent
- 6. 6/11 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. 2. One-Shot Query Planning Agent 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. 3. Tool Use Agent 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. 4. ReAct Agent 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: Upon receiving a user query, the agent identifies the suitable tool (if needed) and gathers its necessary input. The selected tool is invoked with the input, and its output is stored. The agent then retrieves the tool’s history, encompassing both input and output. Based on this information, it decides the next course of action. This iterative process continues until the agent concludes tasks and responds to the user.
- 7. 7/11 5. Dynamic Planning & Execution Agent 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: Outlining the steps necessary to fulfill an input query plan, essentially creating a computational graph or directed acyclic graph (DAG). Identifying the tools, if any, required for executing each step in the plan and performing them with the necessary inputs. 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. How to Implement Agentic RAG?
