[gotcha] Regenerate or retry button returns identical or near-identical AI response

On retry, modify generation parameters: increase temperature \(e.g., from 0 to 0.7\), or append a hidden system/user message nudge like 'Provide a different approach.' Alternatively, change the seed parameter. Never retry with identical parameters and expect different output.

Journey Context:
Users expect 'regenerate' to work like asking a human the same question twice — getting a meaningfully different answer. But at temperature 0, the model is deterministic: identical input produces identical output. Even at low temperatures \(0.1-0.3\), responses are nearly identical because the probability distribution is sharply peaked. Developers often don't discover this because they test with varied prompts, not repeated identical ones. The naive fix of cranking temperature high degrades response quality for first attempts. The correct approach is to introduce variation only on retry: keep temperature low for the initial response \(quality\), then increase it or add a prompt nudge for retries \(variety\). This gives users the 'different perspective' they expect without sacrificing first-response quality.
