Various usage patterns of Agentic RAG
7/17
Agents within a RAG framework exhibit various usage patterns, each tailored to specific
tasks and objectives. These usage patterns showcase the versatility and adaptability of
agents in interacting with RAG systems. Below are the key usage patterns of agents
within a RAG context:
1. Utilizing an existing RAG pipeline as a tool:
Agents can employ pre-existing RAG pipelines as tools to accomplish specific tasks
or generate outputs. By utilizing established pipelines, agents can streamline their
operations and leverage the capabilities already present within the RAG framework.
2. Functioning as a standalone RAG tool:
Agents can function autonomously as RAG tools within the framework. This allows
agents to generate responses independently based on input queries without relying
on external tools or pipelines.
3. 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 the query at query time. This tool retrieval enables
agents to adapt their actions based on the specific requirements of each query.
4. Query planning across existing tools:
Agents are equipped to perform query planning tasks by analyzing input queries
and selecting suitable tools from a predefined set of existing tools within the RAG
system. This allows agents to optimize the selection of tools based on the query
requirements and desired outcomes.
5. Selection of tools from the candidate pool:
In situations where the RAG system offers a wide array of tools, agents can help
choose the most suitable one from the pool of candidate tools retrieved according to
the query. This selection process ensures that the chosen tool aligns closely with
the query context and objectives.
These usage patterns can be combined and customized to create complex RAG
applications tailored to specific use cases and requirements. Through harnessing these
patterns, agents operating within a RAG framework can efficiently accomplish various
tasks, enhancing the overall efficiency and effectiveness of the system.
Agentic RAG: Extending traditional Retrieval-Augmented
Generation(RAG) pipelines with intelligent agents
Agentic RAG (Retrieval-Augmented Generation) is an extension of the traditional RAG
framework that incorporates the concept of agents to enhance the capabilities and
functionality of the system. In an agentic RAG, agents are used to orchestrate and
manage the various components of the RAG pipeline, as well as to perform additional
tasks and reasoning that go beyond simple information retrieval and generation.
In a traditional RAG system, the pipeline typically consists of the following components:
1. Query/Prompt: The user’s input query or prompt.
8/17
2. Retriever: A component that searches through a knowledge base to retrieve
relevant information related to the query.
3. Knowledge base: The external data source containing the information to be
retrieved.
4. Large Language Model (LLM): A powerful language model that generates an
output based on the query and the retrieved information.
In an agentic RAG, agents are introduced to enhance and extend the functionality of this
pipeline. Here’s a detailed explanation of how agents are integrated into the RAG
framework:
1. Query understanding and decomposition
Agents can be used to understand the user’s query or prompt better, identify its
intent, and decompose it into sub-tasks or sub-queries that can be more effectively
handled by the RAG pipeline.
For example, a complex query like “Provide a summary of the latest developments
in quantum computing and their potential impact on cybersecurity” could be broken
down into sub-queries like “Retrieve information on recent advancements in
quantum computing” and “Retrieve information on the implications of quantum
computing for cybersecurity.”
2. Knowledge base management
Agents can curate and manage the knowledge base used by the RAG system.
This includes identifying relevant sources of information, extracting and structuring
data from these sources, and updating the knowledge base with new or revised
information.
Agents can also select the most appropriate knowledge base or subset of the
knowledge base for a given query or task.
3. Retrieval strategy selection and optimization
Agents can select the most suitable retrieval strategy (for example, keyword
matching, semantic similarity, neural retrieval) based on the query or task at hand.
They can also fine-tune and optimize the retrieval process for better performance,
considering factors like query complexity, domain-specific knowledge requirements,
and available computational resources.
4. Result synthesis and post-processing
After the RAG pipeline generates an initial output, agents can synthesize and post-
process the result.
This may involve combining information from multiple retrieved sources, resolving
inconsistencies, and ensuring the final output is coherent, accurate, and well-
structured.
9/17
Agents can also apply additional reasoning, decision-making, or domain-specific
knowledge to enhance the output further.
5. Iterative querying and feedback loop
Agents can facilitate an iterative querying process, where users can provide
feedback, clarify their queries, or request additional information.
Based on this feedback, agents can refine the RAG pipeline, update the knowledge
base, or adjust the retrieval and generation strategies accordingly.
6. Task orchestration and coordination
For complex tasks that require multiple steps or sub-tasks, agents can orchestrate
and coordinate the execution of these sub-tasks through the RAG pipeline.
Agents can manage the flow of information, distribute sub-tasks to different
components or models, and combine the intermediate results into a final output.
7. Multimodal integration
Agents can facilitate the integration of multimodal data sources (e.g., images,
videos, audio) into the RAG pipeline.
This allows for more comprehensive information retrieval and generation
capabilities, enabling the system to handle queries or tasks that involve multiple
modalities.
8. Continuous learning and adaptation
Agents can monitor the RAG system’s performance, identify areas for improvement,
and facilitate continuous learning and adaptation.
This may involve updating the knowledge base, fine-tuning retrieval strategies, or
adjusting other components of the RAG pipeline based on user feedback,
performance metrics, or changes in the underlying data or domain.
By integrating agents into the RAG framework, agentic RAG systems can become more
flexible and adaptable and capable of handling complex tasks that require reasoning,
decision-making, and coordination across multiple components and modalities. Agents
act as intelligent orchestrators and facilitators, enhancing the overall functionality and
performance of the RAG pipeline.
Types of agentic RAG based on function
RAG agents can be categorized based on their function, offering a spectrum of
capabilities ranging from simple to complex, with varying costs and latency. They can
serve purposes like routing, one-shot query planning, utilizing tools, employing reason +
act (ReAct) methodology, and orchestrating dynamic planning and execution.
Routing agent
10/17
The routing agent employs a Large Language Model (LLM) to determine which
downstream RAG pipeline to select. This process constitutes agentic reasoning, wherein
the LLM analyzes the input query to make an informed decision about selecting the most
suitable RAG pipeline. This represents the fundamental and simple form of agentic
reasoning.

One-shot query planning agent
The query planning agent divides a complex query into parallelizable subqueries, each of
which can be executed across various RAG pipelines based on different data sources.
The responses from these pipelines are then amalgamated into the final response.
Basically, in query planning, the initial step involves breaking down the query into
subqueries, executing each one across suitable RAG pipelines, and synthesizing the
results into a comprehensive response.

required from external sources such as an API, an SQL database, or an application with
an API interface. This additional data serves as context to enhance the input query before
it is processed by the LLM. In such cases, the agent can utilize a RAG too spec.

Moving to a higher level involves incorporating reasoning and actions that are executed
iteratively over a complex query. Essentially, this encompasses a combination of routing,
query planning, and tool use into a single entity. A ReAct agent is capable of handling
12/17
sequential multi-part queries while maintaining state (in memory). The process involves
the following steps:
1. Upon receiving a user input query, the agent determines the appropriate tool to
utilize, if necessary, and gathers the requisite input for the tool.
2. The tool is invoked with the necessary input, and its output is stored.
3. The agent then receives the tool’s history, including both input and output and,
based on this information, determines the subsequent course of action.
4. This process iterates until the agent completes tasks and responds to the user.

Dynamic planning & execution agent
ReAct currently stands as the most widely adopted agent; however, there’s a growing
necessity to address more intricate user intents. As the deployment of agents in
production environments increases, there’s a heightened demand for enhanced reliability,
observability, parallelization, control, and separation of concerns. Essentially, there’s a
requirement for long-term planning, execution insight, efficiency optimization, and latency
reduction.
At a fundamental level, these efforts aim to segregate higher-level planning from short-
term execution. The rationale behind such agents involves:
1. Outlining the necessary steps to fulfill an input query plan, essentially creating the
entire computational graph or directed acyclic graph (DAG).
2. Determine the tools, if any, required for executing each step in the plan and perform
them with the necessary inputs.
This necessitates the presence of 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. Thereupon, the executor 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.

Adaptability Limited ability to adapt to changing situations or new information. Can adjust its approach based on feedback and real-time observations. These differences underscore the potential of agentic RAG, which enhances information retrieval and empowers AI systems to actively engage with and navigate complex environments, leading to more effective decision-making and task completion. Various usage patterns of Agentic RAG
  • 7. 7/17 Agents within a RAG framework exhibit various usage patterns, each tailored to specific tasks and objectives. These usage patterns showcase the versatility and adaptability of agents in interacting with RAG systems. Below are the key usage patterns of agents within a RAG context: 1. Utilizing an existing RAG pipeline as a tool: Agents can employ pre-existing RAG pipelines as tools to accomplish specific tasks or generate outputs. By utilizing established pipelines, agents can streamline their operations and leverage the capabilities already present within the RAG framework. 2. Functioning as a standalone RAG tool: Agents can function autonomously as RAG tools within the framework. This allows agents to generate responses independently based on input queries without relying on external tools or pipelines. 3. 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 the query at query time. This tool retrieval enables agents to adapt their actions based on the specific requirements of each query. 4. Query planning across existing tools: Agents are equipped to perform query planning tasks by analyzing input queries and selecting suitable tools from a predefined set of existing tools within the RAG system. This allows agents to optimize the selection of tools based on the query requirements and desired outcomes. 5. Selection of tools from the candidate pool: In situations where the RAG system offers a wide array of tools, agents can help choose the most suitable one from the pool of candidate tools retrieved according to the query. This selection process ensures that the chosen tool aligns closely with the query context and objectives. These usage patterns can be combined and customized to create complex RAG applications tailored to specific use cases and requirements. Through harnessing these patterns, agents operating within a RAG framework can efficiently accomplish various tasks, enhancing the overall efficiency and effectiveness of the system. Agentic RAG: Extending traditional Retrieval-Augmented Generation(RAG) pipelines with intelligent agents Agentic RAG (Retrieval-Augmented Generation) is an extension of the traditional RAG framework that incorporates the concept of agents to enhance the capabilities and functionality of the system. In an agentic RAG, agents are used to orchestrate and manage the various components of the RAG pipeline, as well as to perform additional tasks and reasoning that go beyond simple information retrieval and generation. In a traditional RAG system, the pipeline typically consists of the following components: 1. Query/Prompt: The user’s input query or prompt.
  • 8. 8/17 2. Retriever: A component that searches through a knowledge base to retrieve relevant information related to the query. 3. Knowledge base: The external data source containing the information to be retrieved. 4. Large Language Model (LLM): A powerful language model that generates an output based on the query and the retrieved information. In an agentic RAG, agents are introduced to enhance and extend the functionality of this pipeline. Here’s a detailed explanation of how agents are integrated into the RAG framework: 1. Query understanding and decomposition Agents can be used to understand the user’s query or prompt better, identify its intent, and decompose it into sub-tasks or sub-queries that can be more effectively handled by the RAG pipeline. For example, a complex query like “Provide a summary of the latest developments in quantum computing and their potential impact on cybersecurity” could be broken down into sub-queries like “Retrieve information on recent advancements in quantum computing” and “Retrieve information on the implications of quantum computing for cybersecurity.” 2. Knowledge base management Agents can curate and manage the knowledge base used by the RAG system. This includes identifying relevant sources of information, extracting and structuring data from these sources, and updating the knowledge base with new or revised information. Agents can also select the most appropriate knowledge base or subset of the knowledge base for a given query or task. 3. Retrieval strategy selection and optimization Agents can select the most suitable retrieval strategy (for example, keyword matching, semantic similarity, neural retrieval) based on the query or task at hand. They can also fine-tune and optimize the retrieval process for better performance, considering factors like query complexity, domain-specific knowledge requirements, and available computational resources. 4. Result synthesis and post-processing After the RAG pipeline generates an initial output, agents can synthesize and post- process the result. This may involve combining information from multiple retrieved sources, resolving inconsistencies, and ensuring the final output is coherent, accurate, and well- structured.
  • 9. 9/17 Agents can also apply additional reasoning, decision-making, or domain-specific knowledge to enhance the output further. 5. Iterative querying and feedback loop Agents can facilitate an iterative querying process, where users can provide feedback, clarify their queries, or request additional information. Based on this feedback, agents can refine the RAG pipeline, update the knowledge base, or adjust the retrieval and generation strategies accordingly. 6. Task orchestration and coordination For complex tasks that require multiple steps or sub-tasks, agents can orchestrate and coordinate the execution of these sub-tasks through the RAG pipeline. Agents can manage the flow of information, distribute sub-tasks to different components or models, and combine the intermediate results into a final output. 7. Multimodal integration Agents can facilitate the integration of multimodal data sources (e.g., images, videos, audio) into the RAG pipeline. This allows for more comprehensive information retrieval and generation capabilities, enabling the system to handle queries or tasks that involve multiple modalities. 8. Continuous learning and adaptation Agents can monitor the RAG system’s performance, identify areas for improvement, and facilitate continuous learning and adaptation. This may involve updating the knowledge base, fine-tuning retrieval strategies, or adjusting other components of the RAG pipeline based on user feedback, performance metrics, or changes in the underlying data or domain. By integrating agents into the RAG framework, agentic RAG systems can become more flexible and adaptable and capable of handling complex tasks that require reasoning, decision-making, and coordination across multiple components and modalities. Agents act as intelligent orchestrators and facilitators, enhancing the overall functionality and performance of the RAG pipeline. Types of agentic RAG based on function RAG agents can be categorized based on their function, offering a spectrum of capabilities ranging from simple to complex, with varying costs and latency. They can serve purposes like routing, one-shot query planning, utilizing tools, employing reason + act (ReAct) methodology, and orchestrating dynamic planning and execution. Routing agent
  • 10. 10/17 The routing agent employs a Large Language Model (LLM) to determine which downstream RAG pipeline to select. This process constitutes agentic reasoning, wherein the LLM analyzes the input query to make an informed decision about selecting the most suitable RAG pipeline. This represents the fundamental and simple form of agentic reasoning. Query Agent Router Response RAG : Query Engine A RAG : Query Engine B Tools LLM LeewayHertz An alternative routing involves choosing between summarization and question-answering RAG pipelines. The agent evaluates the input query to decide whether to direct it to the summary query engine or the vector query engine, both configured as tools. Query Agent Router Response RAG : Summary Query Engine RAG : Vector Query Engine Tools LeewayHertz LLM One-shot query planning agent The query planning agent divides a complex query into parallelizable subqueries, each of which can be executed across various RAG pipelines based on different data sources. The responses from these pipelines are then amalgamated into the final response. Basically, in query planning, the initial step involves breaking down the query into subqueries, executing each one across suitable RAG pipelines, and synthesizing the results into a comprehensive response.

However, there are instances where additional data is required from external sources such as an API, an SQL database, or an application with an API interface. This additional data serves as context to enhance the input query before it is processed by the LLM. In such cases, the agent can utilize a RAG too spec. Agent Synthesizer Response External API Vector DB SQL DB Open Weather Map Tools Query LeewayHertz LLM ReAct agent ReAct = Reason + Act with LLMs Moving to a higher level involves incorporating reasoning and actions that are executed iteratively over a complex query. Essentially, this encompasses a combination of routing, query planning, and tool use into a single entity. A ReAct agent is capable of handling
  • 12. 12/17 sequential multi-part queries while maintaining state (in memory). The process involves the following steps: 1. Upon receiving a user input query, the agent determines the appropriate tool to utilize, if necessary, and gathers the requisite input for the tool. 2. The tool is invoked with the necessary input, and its output is stored. 3. The agent then receives the tool’s history, including both input and output and, based on this information, determines the subsequent course of action. 4. This process iterates until the agent completes tasks and responds to the user. LeewayHertz LM Reasoning Traces Reasoning Traces LM LM Env Env Actions Actions Observations Observations (Reason + Act) ReAct Reason Only Act Only Dynamic planning & execution agent ReAct currently stands as the most widely adopted agent; however, there’s a growing necessity to address more intricate user intents. As the deployment of agents in production environments increases, there’s a heightened demand for enhanced reliability, observability, parallelization, control, and separation of concerns. Essentially, there’s a requirement for long-term planning, execution insight, efficiency optimization, and latency reduction. At a fundamental level, these efforts aim to segregate higher-level planning from short- term execution. The rationale behind such agents involves: 1. Outlining the necessary steps to fulfill an input query plan, essentially creating the entire computational graph or directed acyclic graph (DAG). 2. Determine the tools, if any, required for executing each step in the plan and perform them with the necessary inputs. This necessitates the presence of 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. Thereupon, the executor 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.
