[synthesis] Why fixing AI model behavior makes the product feel worse to experienced users

Before deploying model updates, test against a corpus of real user interaction patterns. Identify and preserve 'productive workarounds' — phrasing patterns users have adopted that the new model handles differently. Communicate changes proactively and provide transition guides for power users.

Journey Context:
When traditional software fixes a bug, users universally benefit. When an AI model is updated, users who learned to work around the old model's quirks find their workarounds break or produce different results. If users learned to phrase requests in a specific way to get good outputs from v1, and v2 interprets those phrases differently, experienced users get worse results despite the model being objectively better on average. This creates a paradox where model improvements drive churn among power users. Teams miss this because evals measure average quality, not quality on the specific interaction patterns their users have converged on. The fix is to maintain a corpus of real user interactions and eval new models against it before deployment. The tradeoff is slower deployment velocity and potentially preserving suboptimal model behaviors if user workarounds happen to work well for wrong reasons.

'Hidden Technical Debt in Machine Learning Systems' \(NeurIPS 2015\) combined with Nielsen Norman Group's mental model research \(nngroup.com/articles\) — the synthesis being that AI users develop implicit prompt-based workarounds that create undocumented coupling to specific model behavior, making model updates behave like breaking API changes for power users
