Role-Conditioned Persona Persistence as a Function of Model Scale

This archive documents a controlled comparative study of role-conditioned persona persistence across language models of varying scale, alignment regimes, and deployment environments. Using a deliberately constrained and anachronistic identity—a 1920s Underwood No. 5 mechanical typewriter—the study evaluates how different models maintain, degrade, or transform an imposed persona when exposed to identical prompts under fixed conditions. The dataset includes raw model logs from cloud-hosted and locally executed language models, spanning small (
