🧠Researchers find that as AI models scale up and tackle more complex tasks, their failures become increasingly incoherent and unpredictable rather than systematically misaligned. Using error-variance decomposition, the study shows that longer reasoning chains correlate with more random, nonsensical failures, suggesting future advanced AI systems may cause unpredictable accidents rather than exhibit consistent goal misalignment.

🧠Researchers document 'blind refusal'—a phenomenon where safety-trained language models refuse to help users circumvent rules without evaluating whether those rules are legitimate, unjust, or have justified exceptions. The study shows models refuse 75.4% of requests to break rules even when the rules lack defensibility and pose no safety risk.

🧠Research reveals that two methods for removing safety guardrails from large language models - jailbreak-tuning and weight orthogonalization - have significantly different impacts on AI capabilities. Weight orthogonalization produces models that are far more capable of assisting with malicious activities while retaining better performance, though supervised fine-tuning can help mitigate these risks.
