[gotcha] Regenerate/retry button returns the exact same response at low temperature

On retry, either: \(1\) use OpenAI's seed parameter with a different value for controlled variation, \(2\) slightly increase temperature for retry attempts, or \(3\) append a hidden random nonce to the system prompt to break determinism. Always communicate to users that retrying may produce similar results.

Journey Context:
At temperature=0, LLMs are nearly deterministic — same prompt yields same output. Users click regenerate expecting a fresh take but get a carbon copy. Even at moderate temperatures \(0.3-0.7\), outputs can cluster around similar patterns. The naive fix of cranking temperature to 1.0 on retry degrades quality. OpenAI's seed parameter offers a middle ground: controlled reproducibility with the ability to get different results by varying the seed. The UX must also set expectations — a try a different approach affordance \(prompting the user to rephrase\) is often more effective than a raw retry button.
