[counterintuitive] is fine-tuning better than few-shot prompting for custom behavior

Start with prompting and RAG. Only fine-tune for style, format, or domain vocabulary adoption, not for injecting new factual knowledge.

Journey Context:
Developers fine-tune to teach models new facts or complex behaviors, expecting it to memorize better than context. Fine-tuning is prone to catastrophic forgetting and is terrible at teaching new factual knowledge compared to RAG. Fine-tuning adjusts weights for \*behavior\* \(how to speak\), not \*knowledge\* \(what to speak\).
