Agentic RAG is an advanced RAG implementation that deploys AI agents to solve complex problems and extend the LLM's capabilities with AI decision-making.

Generative AI was once the next big thing in the tech world, but soon users found its limitations. It retrieves answers from vast datasets, which can sometimes make responses vague or incorrect, also called AI hallucination.

To tackle that, Retrieval-Augmented Generation (RAG) took the spotlight by grounding LLMs to up-to-date, external knowledge. At the same time, AI agents also became popular for tasks that required sequential decision-making and planning.

Now that the AI role in managing tasks is becoming more complex, relying on RAG or AI agents isn't enough. That's where Agentic RAG steps in.

Agentic RAG combines RAG's capabilities with AI agents' decision-making skills. In this guide, we will explore agentic RAG thoroughly, covering its working principles, use cases, challenges, and best practices.

What is Agentic RAG?

Agentic RAG is a system that combines Retrieval-Augmented Generation (RAG) and AI agents to create more adaptive and capable AI applications. Before we get deep into agentic RAG, let's first clarify these two technologies.

Retrieval-Augmented Generation (RAG) is a technique to build LLM-powered applications. It allows the LLM to access the external knowledge source to get relevant context and minimize hallucinations. Simply put, it enhances the accuracy and reliability of LLMs by providing information from relevant data sources.


rag workflow

An AI agent is an autonomous system that has access to memory and external tools to perceive their environment, reason, and take actions. Agentic AI elevates the capabilities of AI agents further by integrating reasoning and planning. This turns agents to be proactive instead of reactive and handle more tasks autonomously. These agents become useful in tasks related to planning, decision-making, and interaction with complex workflows.

Agentic RAG integrates both technologies by embedding agentic agents into the RAG pipeline. This makes the system capable of handling multi-step task execution and dynamic decision-making. It makes the system well aware of what needs to be done and how to find the information it needs to perform the task.

An example of agentic RAG is in healthcare diagnostics. A doctor inputs a patient's symptoms, and the system retrieves up-to-date medical research, suggests diagnoses, and proposes treatments. The system can even ask follow-up questions to refine its recommendations.

Standard RAG vs. Agentic RAG: Key Differences

Think of agentic RAG as the advancement to standard RAG that is more capable of facilitating complex workflows. Check out the comparison table of RAG vs agentic RAG to better understand the key differences:

In short, RAG is useful for basic Q&A and research, while agentic RAG dominates in complex and data-intensive applications.

How does Agentic RAG work?

Agentic RAG has four pillars, i.e., autonomy, data retrieval, augmented generation, and feedback loop. The details of these pillars are as follows:

Autonomy in Decision-Making

Agentic RAG don't need explicit instructions to know what is required to complete a task. Even if it has got an incomplete question or dataset, it can intelligently determine the missing elements and find them. Sometimes, it can even go for iterative querying. This approach makes it effective as a proactive problem-solver.

Retrieval of Relevant Information

Agentic RAG accesses real-time data using advanced tools, such as databases, APIs, and knowledge graphs. It extracts up-to-date information instead of just static, pre-trained knowledge. For example, it can pull the latest research insights, current market trends, and other information.

Contextual Accurate Responses with Augmented Generation

After data retrieval, agentic RAG LangChain processes and integrates the data into a coherent response using LLMs. It ensures that responses are context-aware, meaningful, and accurate.

Feedback Loop for Continuous Learning

Lastly, agentic RAG has a feedback loop in place to refine its responses over time. Every interaction with the system makes it smarter and more intelligent, which drives long-term performance enhancement.

Workflow of Agentic RAG

All the above pillars of agentic RAG work together as a single unit for data retrieval, augmentation, and generation. Let's now take a look at what a typical workflow of LangChain agentic RAG looks like:

  • Prompt: The user specifies a query to the system.
  • AI Agent: Breaks down the query, determines missing context through iterative querying, and autonomously selects tools (APIs or databases) to retrieve relevant data.
  • Knowledge Base: Pulls structured (databases), unstructured (research papers), or real-time data (APIs/news feeds).
  • LLM: Synthesizes retrieved data into a contextual response.
  • Feedback Loop: Refines future outputs by learning from user interactions.

In this way, a typical agentic RAG system uses different components to handle simple to complex workflows with greater knowledge and automation.

Real-World Use Cases and Benefits of Agentic RAG for Enterprises

Agentic RAG has a diverse range of applications. It is already in action across different enterprises and industries.


use cases and benefits

Some of the common applications of agentic RAG include:

  • Customer Support: Agentic RAG empowers support systems to adapt responses to individual customer contexts. For example, it can resolve order delays by offering real-time solutions like expedited shipping or discounts. Plus, these systems refine their interactions over time by learning from historical data.
  • Healthcare: Clinicians use agentic RAG to synthesize the latest medical research into evidence-based recommendations. This improves diagnostic precision and treatment plans. Plus, the technology also enhances patient safety by flagging drug interactions and supports medical training with instant access to evolving clinical guidelines.
  • Education: Intelligent tutoring systems use agentic RAG to personalize learning paths by retrieving content aligned with a student's progress and preferred learning style.
  • Business Intelligence: Enterprises automate KPI analysis and report generation with agentic RAG. The system identifies hidden trends in data and facilitates proactive decision-making to outpace competitors.
  • Scientific Research: Researchers are using agentic RAG to identify relevant studies and extract key insights. This approach reduces the time spent on literature reviews.

In short, agentic RAG can facilitate different departments and industries with its intelligent reasoning and context-aware decision-making. Below are three real-world use cases of Agentic RAG:
