Researchers introduce Non-Conversational Planning Theory of Mind (NCP-ToM) and a novel evaluation framework, NCP-ExploreToM, which tests whether LLMs can manipulate belief states in other agents by moving objects or directing characters rather than through dialogue. Six frontier models (including GPT-5, Gemini 2.5 Pro, and Claude 4 series) and human participants were evaluated across 600 task instances; GPT-5 achieved ~80% success and was the only model to outperform humans, though it remained less robust across contexts. All models, like humans, performed better at inducing true belief states than false ones, which the authors flag as a positive alignment signal. The work highlights both emerging agentic social-reasoning capabilities and new manipulation/misinformation risks that passive ToM benchmarks fail to capture.
