[gotcha] The 'regenerate' button implies different results but may return identical output at low temperature

On retry/regenerate, slightly increase temperature or add prompt variation to ensure meaningfully different outputs. Alternatively, rename the action to 'try a different approach' and automatically rephrase the underlying prompt. Never offer a 'regenerate' action that silently resubmits the identical request with identical parameters.

Journey Context:
When users click 'regenerate' after an unsatisfactory AI response, they expect a meaningfully different answer. But at temperature=0 \(deterministic\), the same prompt produces identical output. Even at low temperatures \(0.1-0.3\), outputs may be nearly identical. Users click regenerate multiple times, get the same answer, and conclude the system is broken. The UX contract of 'regenerate' is 'give me a different take,' but the technical implementation is 'resubmit the same request.' These are fundamentally different operations. The fix is to either bump temperature on retries, add variation to the prompt, or rename the action to set correct expectations. The counter-intuitive part: developers set low temperature for reliability, then add a 'regenerate' button that only works with high temperature — creating a direct contradiction between the system's design goal and the user's expectation.
