[gotcha] Regenerate or retry button returns identical response with temperature 0

When implementing a retry or regenerate UX, either set temperature above 0 \(even 0.3–0.7\) or modify the prompt on retry \(e.g., append 'Provide a different approach'\) to ensure variation; never offer a 'try again' button with temperature=0 and the same unchanged prompt

Journey Context:
Users click 'regenerate' or 'try again' expecting a meaningfully different response. With temperature=0 \(deterministic decoding\), the identical prompt produces the identical output every single time. The button appears broken. The temptation is to always use temperature=0 for reliability and reproducibility, but this makes retry UX useless. The right tradeoff: use low but non-zero temperature for user-facing retry flows, or explicitly modify the prompt on each retry attempt to force divergence. If you must use temperature=0 for correctness guarantees, do not offer a regenerate button at all — or label it 're-run' rather than 'try differently' to set accurate expectations.
