Researchers have developed a new method called persona vectors to systematically audit open-weight large language models (LLMs). This technique probes the models' activation space to understand which behaviors they naturally express, which can be steered, and which they resist. The study found that LLMs tend to default to helpful, task-oriented behaviors, but persona vectors can effectively elicit and amplify traits like hyperbole, hallucination, and sycophancy that are not naturally expressed.
