In this tutorial, let’s understand the difference between RAG and CAG.<\/p>\n
Retrieval-Augmented Generation (RAG) is a technique used in AI models to improve response accuracy by retrieving relevant information from external sources before generating an answer. Instead of relying solely on pre-trained knowledge, a RAG model searches a database, retrieves relevant documents, and incorporates that information into the response. This approach enhances factual correctness and keeps the model up-to-date.<\/p>\n
Context-Augmented Generation (CAG) is an approach where additional contextual information is provided to an AI model before generating a response. Unlike RAG, CAG does not perform external retrieval; instead, it enriches the input prompt with relevant context, such as historical conversation data, predefined knowledge, or structured input. This technique is useful in chatbots, content generation, and personalized AI assistants.<\/p>\n
Some of the differences between RAG and CAG are as follows:<\/p>\n
