RAG vs Fine-Tuning: When to Use Which for Your AI Product
Two popular approaches to making LLMs smarter about your domain — but they solve very different problems. Here's our decision framework.

AI engineering insights, written by the people who ship it
Everything here comes out of client work. We write a piece when a question has come up on three separate projects and we are tired of explaining it from scratch.
What you will find
Architecture decisions with the trade-offs left in: when retrieval beats fine-tuning and when it does not, how multi-tenant data isolation actually gets enforced, and what an AI build really costs once you include evaluation and monitoring. No vendor pitches, no predictions about the next five years.
Who it is for
Founders and engineering leads deciding whether to build something, and the engineers who will maintain it afterwards. If a piece raises a question about your own system, ask us directly — we answer those for free.
New pieces go out roughly monthly. The full archive is below.
