AI Shatters 76-Year-Old Benchmark: GPT-4.5 Officially Passes Turing Test in Breakthrough Study
Techstrong.ai, Friday, May 29th, 2026
GPT-4.5 becomes the first AI to pass the Turing test with a 73% success rate in a landmark UCSD study.
Researchers at UC San Diego have demonstrated that GPT-4.5 has successfully passed the Turing test, achieving a 73% success rate in fooling human interrogators during five-minute text-based conversations.
The groundbreaking study, published in the Proceedings of the National Academy of Sciences, evaluated multiple AI systems alongside the 1960s chatbot ELIZA, revealing a stark technological divide with GPT-4.5 significantly outperforming other models.
This achievement breaks a 76-year-old benchmark originally established by Alan Turing in 1950 as a measure of machine intelligence. The researchers warn of serious implications including workforce displacement, erosion of social engagement, and potential public manipulation through AI agents capable of mimicking humans.
