The scenario is like this– In early 2023, GPT, or Generative AI, swept everything by surprise with its content-generation and QnA abilities. For most, it was a transformative shift. However, the limitations of static training data soon emerged. Generative AI exhibited inaccuracy and hallucinations for real-time response generation and autonomous task management with the retrieved information. Then RAG, or retrieval-augmented generation, appeared to address the limitations of Generative AI by enhancing LLMs with real-time data retrieval to provide contextual answers.
But, as people continue to seek answers to nuanced and context-aware questions, RAG lacks adaptability and multi-step reasoning for complex task management. This is where Agentic Retrieval-Augmented Generation, or RAG, comes into play. By elevating traditional RAG’s approach of searching information and leveraging contextual meaning from vast data points, Agentic RAG ensures you can redefine AI-driven information retrieval and contribute to real-world applications for multi-step complex workflows, including simple to common workflows.
Our article highlights the fundamentals of agentic RAG, including its use cases, benefits, and implementation strategies.
The fundamental understanding of agentic RAG is embedding autonomous AI agents in the RAG pipeline. By embedding RAGs with AI agents, traditional RAGs can become independent agents that can gain extended retrieval capabilities for multi-step reasoning, planning, tool integration, and adapting workflows to meet complex task requirements.
LLM systems that fetch information from external systems and public knowledge are RAG or retrieval-augmented generation. Since RAG works only on static workflows, including external knowledge, it tends to create insufficient answers to solve problems. These systems do not apply reason or validation to the retrieved information, so RAG can struggle to make decisions and complete tasks.
RAG is suitable for static workflows. This means that RAG can work when triggered by a predefined set of workflows that require minimal contextual complexity. There are some substantial reasons for traditional RAGs to fall short of meeting advanced and dynamic query resolution.
These limitations include
Difficulties with information prioritization — Traditional RAG systems are not equipped to sieve information through large datasets and answer nuanced queries. Failure to work with high-quality data, RAGs can surface generic Information.
Agent-based RAG implementation is known as agentic RAG in a very fundamental stage. It means embedding the power of the agency or agents with the LLM-based RAGs to help execute multi-task or complex tasks requiring multi-step reasoning, strategies, and utilization of multiple tools is agentic RAG.
Unlike traditional RAGs, agentic RAG systems can interact with multiple systems to fetch the correct documents, analyze data, and make multi-step reasoning to generate a response. In essence, agentic RAG systems combine multiple agents to delegate specific roles, escalate the implementation of documents, and manage new requirements with sub-agents.
Picture agentic RAG systems as a whole team of experts dedicated to executing a task. For example, if you need to deliver a furniture set to a client, you need various people at your disposal to accomplish the assignment. You need a team of dispatchers, a logistics vehicle, and a driver.
Imagine all of this workforce as agents. So, during the transit, if there is a message popping up and saying that the delivery location would be something else rather than the one registered with the company, your people supervising the task would plan accordingly, make strategic decisions, and execute the task.
Likewise, agentic RAGs can adapt to changing workflows, accomplish tasks by referring to new documents, and make strategic decisions.
An agentic RAG system aims to address the limitations of LLM-based RAGs by combining more intelligent agents and external tools to tackle complex tasks.
The key goal of a RAG system is to retrieve information from various sources. Hence, when agentic RAGs are used for retrieval components, they become retrieval agents. There are multiple retriever systems to which agents have access and become retrieval agents, such as,
Once access is provided to the retriever, agentic RAG systems reason and act over the retrieval scenarios in the following manner.
Agent RAG has some crucial and significant features to help execute tasks. These features include,
Agentic RAG applies a unique orchestration process to streamline question-answering workflows. It breaks down tasks into smaller, more manageable tasks to assign to each agent, ensuring seamless coordination of optimal outcomes.
Agentic RAG agents are designed to recognize and pursue specific objectives to manage more complex and meaningful tasks.
Agents in the RAG pipeline use advanced reasoning and planning to determine the most effective strategies for retrieving information, analyzing it, synthesizing it, and answering complex questions.
Agentic RAG integrates with many data sources and external tools, such as search engines, databases, and APIs, to enhance understanding and make informed decisions.
Agentic RAG systems develop enhanced context over time. They refer to past interactions, user preferences, and evolving scenarios to make informed decisions and take appropriate actions.
Intelligent RAGs learn and evolve. Their external knowledge expands with changing scenarios, helping them improve their capacity and address increasingly complex questions.
Agentic RAG offers extensible customizability and flexibility for specific tasks per domain or industry needs. The best thing is that agents can be designed or trained to handle particular tasks and unique requirements.
Agent-based systems integrate with large language models, allowing agentic RAG to generate accurate and relevant information while reducing hallucinations compared to traditional RAGs.
Traditional RAG, popular as Vanilla RAG, is designed to retrieve information and generate responses but lacks expandability to manage complex and nuanced queries. However, using tools or external tool integration makes RAG more intelligent and powerful in solving complex and dynamic queries with multi-step reasoning. Here is our table of differences between Agentic RAG and traditional RAG based on their key features.
Feature | Vanilla or Traditional RAG systems | Agentic RAG |
Prompt engineering | Acts when prompted and optimized | Dynamically adjusts prompts based on context and goals, reducing human reliance |
Retrieval nature | Static retrieval decision-making and limited context-aware | Dynamically adapts retrieval strategies based on context |
Overhead | High costs due to unoptimized retrievals and additional text generations | Cost-effective due to vector or text-based data storage and optimal data retrieval and generation |
Multi-step complexity management | Requires additional classifiers and models for multi-step reasoning and tool integration | Unleashes multi-step reasoning and seamlessly interacts with tools without the need for tools and classifier |
Decision-making | Static rules drive retrieval and response generation | Decide when and where to retrieve data, evaluate retrieved data quality, and perform post-generation checks on responses |
Retrieval process | Solely depends on the initial query input to retrieve relevant documents | Adjusts to the environment before and during retrieval to gather additional information |
Adaptiveness | Limited adaptability to retrieve information according to changing situations and new information | Extended adaptability to new changes and situations based on a feedback loop and real-time observation |
This comparison table provides enough insights into how Agentic RAG can be powerful when its optimization abilities are combined with context-based retrieval strategies. At the same time, Vanilla RAG or traditional RAG lacks significant retrieval abilities, as it depends on manual optimization and static processes.
Embedding agents in the RAG pipeline builds the foundation for agentic RAG. Based on reasoning and analytical abilities at different stages of task execution, there are several AI agents in the RAG pipeline that retrieve and generate information. These agents constitute how a variety of agentic RAG models execute tasks.
The routing agent leverages LLMs to determine the most relevant RAG pipeline for the query. Using agentic reasoning, LLMs analyze the query and make informed decisions.
Query planning agents break down complex queries into manageable sub-queries or inputs and handle them to agents with access to specific RAG pipelines. Later, query planning agents consolidate all responses into a comprehensive response to solve the user’s request.
Using real-time data and user interactions, this agent type leverages reasoning from multiple components and iterative actions to address more complex queries. To apply this approach, ReAct agents integrate routing, query planning, and tool use into a single workflow to handle multi-step, sequential queries while ensuring context.
This agent model optimizes and adapts to changes in the real-time environment and data requirements. Using its planner and executor components, dynamic planning and execution agents first plan a step-by-step guide for a query; then, the executor performs each step. This iterative process continues until each plan is executed for the final delivery of the task.
As the name appears, this model combines multiple agents with specific skills and knowledge to address complex queries within the RAG framework.
