[gotcha] Regenerate/retry button produces nearly identical AI responses

On retry, do at least one of: increase temperature by 0.2-0.3 above the original setting, append an explicit instruction like 'Provide a substantially different approach' to the system message, or change the seed value. Never retry with identical parameters and prompt.

Journey Context:
Users click regenerate because they want meaningfully different output. But LLMs given the same prompt and similar temperature produce very similar responses—especially with short, unambiguous prompts where the output distribution is sharply peaked. Even temperature=0.7 can produce near-deterministic output for well-specified tasks. The gotcha: developers assume temperature alone provides sufficient variation, but for many prompts the output probability distribution is so concentrated that even high temperature still lands on the same tokens. The model is stuck in a local optimum. The fix requires both parameter variation AND explicit prompt instruction to differ, because temperature changes the sampling distribution but does not change where the probability mass is concentrated.
