[gotcha] Regenerate/retry button returns nearly identical response

On retry, modify generation parameters: increase temperature by 0.2–0.3, append a variation nudge to the system message \(e.g., 'Provide a meaningfully different approach'\), or change the seed. Never retry with identical parameters and identical context.

Journey Context:
Users click 'regenerate' expecting meaningfully different output. But at low temperatures \(which production systems use for reliability\), the same prompt with the same parameters produces very similar responses—especially for structured tasks like code generation or data extraction. The counter-intuitive part: even temperature=0 does not guarantee identical output across all providers, but it does guarantee similar-enough output on retry that users think the button is broken. Teams discover this only after user complaints. The fix is not to raise temperature globally \(which hurts consistency\), but to specifically inject variation on retry attempts. OpenAI's seed parameter can also be used deliberately to force a different output by incrementing the seed value on each retry.
