[gotcha] Regenerate/retry button creates user expectation of a fundamentally different answer but samples from the same distribution

When implementing retry/regenerate, either: \(1\) automatically append a hidden instruction like 'Provide a different approach or perspective' to the prompt before resubmitting, \(2\) offer the user a way to specify what they want different \('more concise', 'different approach', 'more creative'\), or \(3\) increase temperature on retries. Never just re-send the identical prompt and expect user satisfaction.

Journey Context:
Users click 'regenerate' when they don't like the first answer. They expect a meaningfully different response — a different approach, different structure, different perspective. But if you just re-send the same prompt \(even with temperature > 0\), you're sampling from the same conditional distribution. If the model's first answer was in a strong local optimum \(which it often is — models have preferred patterns\), retries produce variations on the same theme. The user gets frustrated: 'I said regenerate, not paraphrase\!' The counter-intuitive insight: retry isn't a retry — it's a new sample from the same distribution. To get a genuinely different answer, you need to change the distribution \(modify the prompt\). The tradeoff is that modifying the prompt makes the retry less 'pure' — you're not comparing two samples from the same distribution. But UX purity matters less than user satisfaction.
