[counterintuitive] fine-tuning for adding new knowledge
Use RAG for new factual knowledge; reserve fine-tuning for altering tone, format, or teaching specific behavioral patterns and styles.
Journey Context:
Developers think fine-tuning is the ultimate way to teach a model new facts. Fine-tuning is like studying for an exam, but it is notoriously bad at memorizing specific facts and prone to hallucinating them. It excels at learning \*how\* to behave \(style, format\). RAG is better for \*what\* to know \(facts\) because it provides explicit, verifiable context at inference time.
