[gotcha] Users expect identical inputs to produce identical outputs but stochastic AI silently violates this mental model

When users re-submit the same prompt, either cache and return the previous response with a Viewing previous result banner, or explicitly label the experience as generative \(AI generates a fresh response each time\). For enterprise and reproducibility contexts, offer a pin this response feature. Never let users discover non-determinism by accident.

Journey Context:
Every other interface in a user's experience is deterministic: clicking the same button produces the same result, submitting the same form returns the same data. AI breaks this fundamental mental model. When a user asks the same question twice and gets two substantively different answers, they do not think stochastic sampling — they think the AI is broken or unreliable. This is especially toxic in enterprise contexts such as legal, medical, and financial where reproducibility is a requirement not a preference. The gotcha is that developers internalize AI's stochastic nature early and stop noticing it, so they never think to address it in the UX. It feels obvious to them. But end users have no framework for understanding why the same question yields different answers, and the resulting confusion erodes trust in the entire system.
