Unlike traditional semantic layers (LookML, DAX) where lock-in is explicit, plain-text AI-native layers appear portable but aren't. Key consequences include: users can't freely choose models without getting inconsistent answers, third-party model updates can silently break previously correct queries with no rollback option, and this creates a genuine argument for running self-hosted models to maintain control. The recipe (hierarchical retrieval, LLM-authored layer, refinement loop) is portable across models, but the tuned artifact is not — swapping models means re-running the entire tuning loop. ## Full article daily.dev links to this article rather than hosting it.
