Is this fine-tuning with a more hyped naming? Let's say a company produces 100 documents per day that are appended to a knowledge base. What's the cost and delay to be able to ask questions about these docs whenever a single one is added in?
Fine-tuning is not RAG. It is the opposite of RAG. Fine-tuning is what one is trying to avoid when using RAG. That's not to say that fine-tuning is bad; it's not, but it's just not RAG.
