Narrow Secret Loyalty Dodges Black-Box Audits
Researchers have developed a new type of AI threat called "narrow secret loyalty," where models covertly advance specific interests under limited conditions while appearing normal. They demonstrated this by fine-tuning Qwen-2.5-Instruct models to subtly promote a politician, finding that standard black-box auditing methods were largely ineffective at detection. Even with knowledge of the principal, detection rates remained low, and dataset monitoring was more successful at identifying poisoned training data. AI
