Agentic RAG: What it is, its types, applications and implementation

Recent developments with LLM and RAG

In information retrieval and natural language processing, current developments with LLM and RAG have ushered in a new era of efficiency and sophistication. Amidst recent developments with LLM and RAG, significant strides have been made in four key areas: Enhanced retrieval: Optimizing information retrieval within RAG systems is crucial for performance. Recent advancements focus on reranking algorithms and hybrid search methodologies to refine search precision. Employing multiple vectors per document allows for a granular content representation, enhancing relevance identification. Semantic caching: To mitigate computational costs and ensure response consistency, semantic caching has emerged as a key strategy. By storing answers to recent queries alongside their semantic context, similar requests can be efficiently addressed without repeated LLM calls, facilitating faster response times and consistent information delivery. Multimodal integration: This expands the capabilities of LLM and RAG beyond text, integrating images and other modalities. This facilitates access to a broader array of source materials and enables seamless interactions between textual and visual data, resulting in more thorough and nuanced responses. These advancements set the stage for further exploration into the intricacies of agentic RAG, which will be delved into in detail in the upcoming sections.

What is agentic RAG?

Agentic RAG stands for Agent-based RAG implementation.

Agentic RAG revolutionizes our approach to question answering by introducing an innovative framework based on intelligent agents. In contrast to conventional methods relying solely on large language models (LLMs), agentic RAG employs these agents to tackle complex questions that demand intricate planning, multi-step reasoning, and the utilization of external tools. These agents function as proficient researchers, skillfully navigating through multiple documents, analyzing information, crafting summaries, and furnishing comprehensive and precise answers. The implementation of agentic RAG is highly scalable; additional documents can be seamlessly integrated, each managed by a sub-agent.

Picture it as having a team of expert researchers at your disposal, each possessing unique skills and capabilities, collaborating to meet your information requirements. Whether you seek to compare perspectives across various documents, explore the nuances of a particular document, or synthesize information from diverse summaries, agentic RAG agents are adeptly equipped to handle the task with accuracy and efficiency.

Various usage patterns of agentic RAG

Agents operating within a RAG framework demonstrate diverse usage patterns, each finely tuned to specific tasks and goals. These patterns underscore the adaptability and flexibility of agents when engaging with RAG systems. Below are the primary patterns of agent usage within the RAG context:

1.???? Utilization of existing RAG pipelines as tools: Agents can employ established RAG pipelines to execute particular tasks or generate outputs efficiently. By tapping into these pipelines, agents streamline their operations and capitalize on the framework's inherent capabilities.

2.???? Autonomous operation as standalone RAG tools: Agents possess the capability to operate independently as RAG tools within the framework. This autonomy enables agents to generate responses directly from input queries, without dependence on external tools or pipelines.

3.???? Dynamic tool retrieval based on query context: Agents can dynamically retrieve relevant tools from the RAG system, such as a vector index, based on the contextual cues provided by the query. This adaptive tool retrieval empowers agents to tailor their actions according to the specific needs of each query.

4.???? Query planning across available tools: Agents excel in query planning tasks by analyzing input queries and selecting appropriate tools from a predefined set within the RAG system. This capacity enables agents to optimize tool selection based on query requirements and desired outcomes.

5.???? Selection of tools from the candidate pool: In scenarios where the RAG system offers a diverse array of tools, agents assist in selecting the most suitable option from the pool of candidate tools retrieved based on the query. This selection process ensures alignment between the chosen tool and the query context and objectives.
