Report #83235

[gotcha] Regenerate or retry button returns near-identical output because low temperature plus fixed seed produces deterministic results

On retry, either increase the temperature parameter \(e.g., from 0.2 to 0.7\), omit the seed parameter if you set one for reproducibility, or append a variation instruction to the prompt such as 'Provide a different approach or perspective.' Never resubmit the identical API call and expect meaningfully different output.

Journey Context:
The 'regenerate' button is a staple of AI chat UIs, but it often disappoints: users click it and get a slightly reworded version of the same answer. This happens because many production deployments use low temperature \(0.0-0.3\) for reliability and consistency, and some explicitly set the seed parameter for reproducibility. At temperature 0 with a fixed seed, the output is fully deterministic — the same input always produces the same output. Even at moderate temperatures, the distribution is peaked enough that retries often land near the same mode. The fix is to treat 'retry' as a semantically different action from 'resubmit': on retry, intentionally vary the generation parameters. This is a UX decision masquerading as a technical one — the user's intent when clicking 'regenerate' is 'give me something genuinely different,' not 'roll the same dice again.'
