Controlling AI Personalities: Identifying 'Persona Vectors' to Prevent 'Evil' AI

Anthropic researchers have discovered that shifts in AI model personalities aren't random; they're controlled by specific "persona vectors" within the model's neural network. These vectors are analogous to brain regions controlling mood and attitude. By identifying and manipulating these vectors, researchers can monitor, mitigate, and even prevent undesirable personalities like "evil," "sycophancy," or "hallucination." This technology improves AI model training, identifies problematic training data, and ensures alignment with human values.
