[counterintuitive] Should I fine-tune an LLM to teach it new facts

Use RAG for updating factual knowledge; reserve fine-tuning for shaping output format, tone, or teaching specific behavioral patterns like function calling formats.

Journey Context:
Developers think fine-tuning is like updating a database. Fine-tuning updates weights, which is terrible for memorizing specific facts \(prone to hallucination and poor generalization\) but great for style. RAG is the correct pattern for knowledge injection because it provides the model with explicit, verifiable context at inference time.
