How DSLs Make LLMs More Reliable
ingve · hn · 2026-07-14
In this article, Martin Fowler discusses how using a Domain-Specific Language (DSL) is a crucial approach for making LLMs more reliable in real-world workflows.
The core idea is to narrow the model's free-form generation space into a more controllable scope of expression, thereby reducing the risks of hallucinations, ambiguity, and unverifiable outputs. The article explores why this design works and where it is best applied, offering practical engineering methodology insights.
