[counterintuitive] Should I adjust both temperature and top\_p together

Alter temperature OR top\_p, but not both; leave the unused parameter at its default \(typically 1.0\) to avoid unpredictable degenerate outputs.

Journey Context:
Developers often tweak both temperature and top\_p to finely control randomness. However, they both alter the probability distribution of the next token, and their interaction is highly non-linear and unpredictable. Lowering temperature flattens/sharpens the distribution, while top\_p truncates it. Tweaking both often leads to degenerate outputs or completely suppressed vocabularies. API providers explicitly recommend altering one, not both.
