AI Can Seem More Human Than Real Humans in a Classic Turing Test, Study Finds
A recent study from UC San Diego indicates that advanced AI can convincingly imitate human conversation in a Turing test. The research found that models like GPT-4.5 were identified as human 73% of the time, raising questions about the nature of humanlike behavior in AI. This challenges traditional views of the Turing test, suggesting it now measures social behavior rather than just intelligence.
- ▪UC San Diego researchers conducted a rigorous Turing test with advanced AI models.
- ▪GPT-4.5 was judged to be human 73% of the time, while LLaMa-3.1-405B was judged human 56% of the time.
- ▪The study suggests that AI's ability to mimic social behavior complicates our understanding of humanlike intelligence.
