In one study, GPT-4.5 was judged to be human 73% of the time, which means that the actual human was judged to be human only 27% of the time. More human than human, as Tyrell would say.

Edit: folks, the standard Turing test involves a computer and a human, and then a judge communicating with both and giving a verdict about which one is the human. The percentages for the two entities being judged will add up to exactly 100%. That's how this test was conducted. Please don't assume I'm a moron.
