Understanding The Key Elements: RAG & Agentic AI

What is RAG?

RAG (Retrieval Augmented Generation) is a technique that connects LLM to the world of information available online in various formats. This maintains relevancy and allows access to all the latest information. 

The RAG pipeline was designed to enhance LLM capabilities by reducing hallucinations and generating contextually accurate results. The two key components of RAG are:

• Retrieval Component—Generally comprises a vector database and an embedding model to retrieve and store information from external sources. 
• Generative Component—Usually consists of an LLM that converts retrieved data into a relevant response based on user input. 

A thorough insight into the RAG pipeline. 

What is Agentic AI?

Agentic AI is a sophisticated system of AI agents that perform their specific goals as part of one complex task. These systems function independently and require minimal or no human intervention. 

Agentic AI systems are proactive. They initiate action to reach pre-defined goals rather than relying on input triggers. The systems utilize LLMs’ capabilities in handling complex reasoning, which helps them make decisions by themselves based on past and present data. 

The core technologies that are combined to build agentic AI are:

• Machine Learning—The process of analyzing, understanding, and learning from new datasets and correlating them with existing data. 
• NLP—To facilitate communication between the system and user by bridging the gap between natural language and computer understanding. 
• LLM—The element that brings ML and NLP together, combining their capabilities to handle multiple queries simultaneously.
• Decision-making Framework—This is the final component that utilizes insights from other parts to automatically generate a decision based on either rule-based or probabilistic models.

Agentic AI + RAG 

What happens when Agentic AI and RAG are combined? It allows users to leverage the best of both. RAG is made for retrieving relevant documents, but it relies on static queries and works on predefined logic. Agentic AI, on the other hand, is autonomous, goal-oriented, proactive, and has a dynamic workflow.  

When combined, agentic AI allows RAG to dynamically engage with the user queries and evaluate and adapt responses to match the task’s complexity. RAG, on the other hand, grounds the agentic AI’s reasoning capabilities to minimize hallucinations through real-time data access. 

Technologically, when agentic AI and RAG are combined, they form a resilient AI system that is intelligent, fully automated, and reliable enough to be integrated into multiple use cases. This advanced solution is called agentic RAG. 

What is Agentic RAG?

Agentic RAG incorporates AI agents into the RAG pipeline to build a system that automatically assesses and determines appropriate actions to achieve desired outcomes and knows where to retrieve the information. 

In contrast to traditional RAG systems that rely on human intervention at every stage of data retrieval, agentic RAG operates autonomously. This makes the system more adaptable to varied requirements, thus enhancing its information retrieval and problem-solving capabilities. 

With Agentic AI, (traditional) RAG gets enhanced from a user query-intensive static information generation tool to a proactive solution that generates relevant and contextually accurate responses. 

To understand it through an example, 

Traditional RAG is like a GPS system that generates the optimal route (information retrieval) based on the destination entered by the user (input). It does not suggest alternative routes (unless done manually) or reroutes in case of roadblocks, traffic, etc. 

Agentic RAG, on the other hand, is like a self-driving vehicle. Based on the destination, it selects the best route and utilizes real-time insights for route optimization (automated situation analysis and decision-making). It automatically recalibrates in case of any roadblocks or changes in destination without manual intervention. 

Autonomous decision-making in RAG upgrades it to an AI assistant rather than a mere tool.  Unlike traditional RAG, it conceptualizes the user input and accordingly adjusts the search and response strategy. Agentic RAG is more adaptable to the dynamic environment, making it more helpful in real-world situations.

How does agentic RAG enhance the Traditional RAG? 

Agentic RAG adds intelligence and flexibility to an otherwise static retrieval model or traditional RAG. It utilizes agents to automate the management of RAG pipeline components through reasoning and intelligent information retrieval. 

The RAG pipeline relies heavily on user input. User query triggers the retriever component to gather relevant information from multiple sources. The information is sent to the LLM (generator) to generate the output.

Agentic RAG optimizes traditional RAG from the first step itself, where AI agents are used for better query comprehension. These agents identify query intent and divide it into multiple subtasks for accelerated task completion. 

Based on the query at hand, agentic RAG decides on retrieval strategies, such as keyword intensive, semantic similarity, etc. The retrieval process is fine-tuned over time to accommodate complex queries, domain-specific requirements, and more. Agentic RAG automates knowledge base management by identifying relevant information sources. They also update the knowledge base periodically or when there’s an update. 

The agents also facilitate the querying process, where the RAG pipeline is improved based on user feedback, auto knowledge base updates, and improved source reliability. Additionally, it facilitates complex task management and coordinates multiple subtasks to generate one combined, cohesive output. 

Agents also allow RAG to tap into comprehensive information retrieval and generation capabilities through multimodal data source integration. The agentic RAG continually monitors system performance and auto-upgrades to adapt to a newer environment.
