Report #24488

[gotcha] Retrying the same AI prompt produces different results each time — users expect software determinism and are confused by variation

Use the \`seed\` parameter for approximate reproducibility where supported. In UX, label retry actions as 'Regenerate' or 'Try differently' — never 'Retry' \(which implies same-input-same-output\). For failure retries, modify the prompt slightly \(append context about the failure\) rather than resending identically.

Journey Context:
Users have a deep mental model that software is deterministic: same input produces same output. AI models sample from probability distributions, so the same prompt produces different completions on each call. When a user gets an unsatisfactory response and clicks 'retry', they expect improvement, but may get something completely different — and potentially worse. The \`seed\` parameter provides only approximate reproducibility \(OpenAI docs explicitly say it's not guaranteed identical output\). The UX fix is linguistic: 'retry' implies repetition, 'regenerate' implies variation. This aligns the user's expectation with the system's actual behavior. For programmatic retries on failure, appending failure context to the prompt \('Previous attempt returned error X, please try a different approach'\) gives the model information to produce a genuinely different result.
