We have domain PDFs and a decent retrieval stack. Leadership keeps asking for fine-tuning. What signals actually justify the cost and ops burden?
When is fine-tuning worth it vs stronger RAG + prompts?

Fine-tune when you need consistent style/format or tool-calling schema adherence that prompting fails at. Keep RAG for facts that change. Many teams over-index on FT before fixing chunking and query rewriting.
