Report #103337

[counterintuitive] Raising temperature makes model outputs truly random and unbiased.

Do not use temperature as a fairness or randomization mechanism; use a cryptographically secure random source when unbiasedness matters.

Journey Context:
Practitioners sometimes crank temperature to 1.0 or above to get variety or 'unbiased' sampling. Hryszko \(2026\) measures Entropic Deviation and finds a structural randomness floor: even under semantically neutral prompts such as empty strings, random ASCII, and nonsense syllables, transformers maintain ED around 0.30, meaning roughly 90% of non-randomness is intrinsic to the weights rather than the prompt. The model literally cannot produce a uniform token distribution. Temperature modulates an already-concentrated prior, so it cannot produce true randomness.
