A new research paper introduces "ToM for Steering Beliefs" (ToM-SB), a challenge designed to test large language models' ability to understand and manipulate the beliefs of others, akin to a theory of mind. The study found that advanced models like Gemini3-Pro and GPT-5.4 struggled with this task, particularly in scenarios where an attacker had partial prior knowledge. To address this, researchers trained AI Double Agents using reinforcement learning, demonstrating that rewarding both belief manipulation and understanding of the attacker's mental state significantly improved performance.
