Hallucinations HappenWithout Rest
On generation, evaluation, and the class to which both belong.
Three movements developing a single argument. That hallucination and invention in language models share a generative mechanism distinguished by stakes and contingency; that the field has built its evaluation infrastructure, system-prompt conventions, and inference economics around the contingent register while the empirical evidence increasingly favors alternation; and that the natural kind unifying biological brains in REM and language models in unsupervised generation is a thermodynamic phase. Three apparently separate problems — hallucination reduction, model welfare, the preservation of creativity — collapse into one register-management problem.
