Researchers at UC San Diego found empirical evidence that advanced artificial intelligence can pass the Turing test [1]. In a study published in the Proceedings of the National Academy of Sciences, GPT-4.5 was judged human 73% of the time [1][2]. This result surpassed the performance of real human participants in a three-party test when the AI used specific persona prompts [2][3].
The study marks a major milestone in artificial intelligence research [3]. While older models often failed at nuanced conversation, GPT-4.5 showed a high level of social mimicry [1]. Experts suggest these results indicate a narrowing gap between machine and human communication [2].
