What is a RAG?

Retrieval-augmented generation (RAG) represents an innovative approach in the generative AI field. RAG integrates the capabilities of neural network models with the wealth of information stored in external knowledge bases. In other words, this method operates by first searching through a comprehensive database to find information relevant to the query at hand. Once AI retrieves relevant data, RAG uses this context to produce responses that are closely tailored to the query’s specifics.

This process allows RAG to address a broad spectrum of questions and topics, leveraging the extensive storage of knowledge available in various databases. The strength of RAG lies in its ability to pull from diverse sources, ensuring that the generated responses benefit from a rich informational foundation. As a result, RAG systems give detailed and knowledgeable answers in many areas without the expensive training that usually comes with creating new neural network models from the beginning.

Furthermore, RAG’s methodology facilitates a dynamic and adaptable AI solution. As the information sources RAG uses are updated and grown, its ability to provide relevant answers gets better. This inherent flexibility makes RAG an attractive option for applications that require access to the latest information or cover topics with fast-changing content.
