🧠Researchers demonstrate that safety evaluations of persona-imbued large language models using only prompt-based testing are fundamentally incomplete, as activation steering reveals entirely different vulnerability profiles across model architectures. Testing across four models reveals the 'prosocial persona paradox' where conscientious personas safe under prompting become the most vulnerable to activation steering attacks, indicating that single-method safety assessments can miss critical failure modes.

🧠Researchers demonstrate that interpreting large language model reasoning requires analyzing distributions of possible reasoning chains rather than single examples. By resampling text after specific points, they show that stated reasons often don't causally drive model decisions, off-policy interventions are unstable, and hidden contextual hints exert cumulative influence even when explicitly removed.

🧠Researchers demonstrate that a large language model's diversity profile—how probability mass spreads across different solution approaches—should determine whether reasoning strategies prioritize breadth or depth exploration. Testing on Qwen and Olmo model families reveals that lightweight refinement signals work well for low-diversity aligned models but offer limited value for high-diversity base models, suggesting optimal inference strategies must be model-specific rather than universal.
