OpenAI's GPT-4.5 model scored 73% in the Turing Test, appearing more human-like than humans, according to a new study.The study, conducted by researchers at the University of California, San Diego, involved nearly 300 participants.The large language model was identified as human 73% of the time when instructed to adopt a persona, surpassing the expected random chance of 50%.The findings suggest that large language models could replace humans in short interactions without being distinguishable.
