Optimising cost, quality and governance together
We compare RAG and fine-tuning approaches in corporate LLM projects with quality, cost and risk dimensions.
“The best way is often hybrid: balance quality and cost with RAG + lightweight fine-tuning.”
Two main approaches stand out in enterprise LLM projects: Retrieval-Augmented Generation (RAG) and fine-tuning. The right choice; Privacy, timeliness, and cost depend on your goals.
For most institutions, the best way is to use RAG+ light fine-tuning. Evaluation metrics, safety and guardrail policies should be designed together.
Outcome: the business goal → architecture match determines success.
