Researchers have explored how large language models internally represent different speaking entities, such as the AI assistant, a role-playing persona, or a narrative character. By analyzing user-expressed emotions and model responses, they used sparse autoencoders to extract features related to these distinct generation settings. Their findings indicate that assistant and role-play personas are not entirely separate, with role-play personas building upon the assistant's core features while diverging stylistically and behaviorally across model layers. Story characters, however, lack the assistant's associated feature core. AI
