Anthropic Persona Vectors: AI Control at the Activation Level
Anthropic’s research team has unveiled a significant development in AI control with “persona vectors,” a technique that uses activation-level manipulation to surgically edit a large language model’s behavior. This new method bypasses the need for costly and often blunt fine-tuning, allowing researchers to directly manipulate complex personality traits like sycophancy, power-seeking, or even specific worldviews.
