[synthesis] Why users interpret AI non-determinism as a product bug and how to fix it

Make non-determinism a visible, controllable UX feature: allow users to 'regenerate' with explicit UI, expose temperature or creativity controls, pin model parameters for repeat interactions in professional contexts, and frame AI outputs as suggestions \('Here's one approach...'\) rather than definitive answers \('The answer is...'\).

Journey Context:
Traditional software has an implicit contract: same input produces same output. Users have decades of mental model built around this. AI products violate this constantly, and users lack a mental model for stochastic systems. When a user repeats an action and gets a different result, they file a bug. When colleagues get different answers to the same prompt, they lose confidence in the product. The naive fix—making AI deterministic by pinning seeds—often degrades output quality because sampling diversity is what makes the outputs good. The synthesis: API documentation discusses reproducibility parameters, HCI research describes mental models, and UX design patterns address user expectations, but only combining them reveals that the solution isn't technical determinism but rather a redesigned UX contract that sets appropriate expectations for variation and gives users control over randomness—turning a perceived bug into a perceived feature.
