Report #61680

[gotcha] Retry mechanism fails 100% of the time when using temperature 0

Use a very low but non-zero temperature \(e.g., 0.1 to 0.2\) for programmatic retries, or implement a fallback model, rather than strictly using temperature 0 for deterministic tasks.

Journey Context:
Developers set temperature to 0 for factual or coding tasks to ensure deterministic, high-confidence outputs. The silent gotcha is that if the model hits a safety boundary, formatting error, or edge case at temperature 0, it will hit it 100% of the time. A 'retry' button that resends the exact same prompt at temp 0 is completely useless and frustrates the user. Introducing a tiny amount of randomness on retry allows the model to escape the local minimum of the error, while still remaining highly deterministic on the first attempt.
