Retrieval Augmented Generation (RAG) is an advanced AI framework crafted to refine the output of extensive language models by employing a blend of external and internal information during answer creation.

At its essence, RAG functions in two main phases: initially, it retrieves a selection of pertinent documents or sections from a large database using a retrieval system grounded in dense vector representations. These mechanisms, which encompass text-based semantic search models like Elastic search and numeric-based vector embeddings, facilitate efficient storage and retrieval of information from a vector database. For domain-specific language models, integrating domain-specific knowledge is pivotal in bolstering RAG’s retrieval precision, particularly in tailoring it to various tasks and addressing highly specific questions amidst a dynamic context, differentiating between open-domain and closed-domain settings to enhance security and dependability.

Following the retrieval of relevant information, RAG integrates this data, encompassing proprietary content such as emails, corporate documents, and customer feedback, to generate responses. This amalgamation empowers RAG to yield highly accurate and contextually pertinent answers customized to specific organizational requirements, ensuring real-time updates are incorporated.

For instance, if an employee seeks information on current remote work guidelines, RAG can access the most recent company policies and protocols to furnish a clear, succinct, and up-to-date response.

By circumventing the cut-off-date constraint of conventional models, RAG not only heightens the precision and reliability of generative AI but also unlocks opportunities for leveraging real-time and proprietary data. This positions RAG as an essential system for businesses striving to uphold high standards of information accuracy and relevance in their AI-driven interactions.
