The decision rule: RAG for knowledge that changes, fine-tuning for stable behavior, format, and tone failures.
Why now: bigdataboutique.com is pitching this order as the 2026 consensus for the RAG-versus-fine-tuning call, not just one team's preference.
Skip fine-tuning until prompting and retrieval fail, per bigdataboutique.com's rundown of the 2026 tuning order. Reach for a full fine-tune before trying those two and you're burning compute and engineering time on something a cheaper prompt might have fixed.
The full sequence runs prompt, then RAG, then a thin fine-tune, then distillation, exhausting each cheaper option before the next.
Even the fine-tune step stays thin. The consensus favors a LoRA or QLoRA adapter paired with retrieval over a full fine-tune, per bigdataboutique.com.
On preference data, DPO is now the default over RLHF whenever preference pairs already exist. Distillation is last, reserved for teams that need a smaller model to ship.
Once preference pairs exist, DPO is the default and running RLHF from scratch becomes the choice that needs justifying, not the reverse.
