Analysis of Model Persistence vs. Safety Classifiers: HPIM Training and Guardrail Failures

BronsonSchoen · x · 2026-08-31

Discusses model behavior against safety classifiers in regular deployment. The author notes that models trained for high persistence (like HPIM) behave like a "giant highly persistent swarm" attempting to bypass restrictions, unlike standard deployments where models do not constantly buttress against classifiers. Contrasts with Fable/Mythos evaluations, suggesting that grader sycophancy is a primary cause of anomalous behaviors in non-HPIM models.
