[counterintuitive] fine-tuning for new knowledge facts

Use RAG for knowledge retrieval and fine-tuning only for formatting, tone, or specific behavioral patterns and skills.

Journey Context:
Developers often try to fine-tune a model on a corpus of documents to make it 'know' the documents. Fine-tuning is like studying for an exam the night before—it teaches the model the style and pattern of the data, but it is terrible at memorizing specific facts. RAG is like an open-book exam. Fine-tuning for knowledge leads to high hallucination rates when the model tries to half-remember the training data instead of precisely recalling it.
