1 Why Retrieval Augmented Generation?

Even the most advanced generative AI models can only generate responses based on the data they have been trained on. They cannot provide accurate answers to questions about information outside their training data. Generative AI models simply don’t know that they don’t know! This leads to inaccurate or inappropriate outputs, sometimes called hallucinations, bias, or, simply said, nonsense.

Retrieval Augmented Generation (RAG) is a framework that addresses this limitation by combining retrieval-based approaches with generative models. It retrieves relevant data from external sources in real time and uses this data to generate more accurate and contextually relevant responses. Generative AI models integrated ...
