GPT-4.5 Passes the Turing Test: Is AI Now More Human Than Humans?
A groundbreaking study from the University of California, San Diego (UCSD) has revealed that advanced AI language models like GPT-4.5 and LLaMa-3.1 may have finally crossed a historic milestone: passing the Turing Test . In fact, GPT-4.5 was identified as human by 73% of participants , outperforming even actual human respondents in some cases. What Is the Turing Test? First proposed by British mathematician Alan Turing in 1950, the Turing Test is a benchmark for assessing machine intelligence. If a human evaluator cannot distinguish between a machine and a human based on natural conversation alone, the machine is said to have passed the test. Key Findings from the UCSD Study Researchers evaluated several AI models—including GPT-4.5 , LLaMa-3.1 , GPT-4o , and the classic ELIZA —to see whether they could fool human participants into thinking they were human. Participants chatted simultaneous...
