Table of contents:

RAG (Retrieval Augmented Generation) is a method of working with Large Language Models when the user writes his own questions, and you programmatically "mix" additional information from some external sources into this question and submit everything entirely to the input of the language model. In other words, you add additional information to the language model's request context, based on which it can provide the user with a more complete and accurate answer. Imagine a user asking the model: "What is the euro exchange rate now?" The language model has no idea what the euro exchange rate is now; it must get this information to answer the question. What should be done? Open the first link in Google for the query "euro to dollar exchange rate" and add the page's contents to the user's question so that LLM can correctly answer the question. DATAFOREST will do the same, you just need to book a call.
