About this paper

Cameron R. Jones, Benjamin K. Bergen

UC San Diego researchers conduct the first empirical demonstration of an AI system passing a standard three-party Turing test, with GPT-4.5 being identified as human 73% of the time when using persona-based prompting while LLaMa-3.1-405B achieved near-chance performance at 56%.

Key insights

  • Prompting strategy significantly impacts model performance in human imitation
  • Common interrogation strategies like small talk and probing social/emotional qualities proved ineffective
  • Participant knowledge of AI and demographics did not affect detection accuracy
