Can AI pass the Turing Test?
Back in the 1950s, mathematician and computer science pioneer Alan Turing posed a deceptively simple question: “Can machines think?” His answer was the Turing Test — a way to judge whether a computer could hold a conversation convincing enough to be mistaken for a human.
Fast forward to today, and top searches on Google still include:

When did AI pass the Turing Test?
Can ChatGPT pass the Turing Test?
Let’s answer those questions now. But first, a bit of history.
What Is the Turing Test?
The setup is simple: a human judge chats via text with two hidden participants—one is a person, the other a computer. If the judge can’t reliably tell who’s who, the machine is said to have passed.
It’s not about solving maths or winning chess matches; it’s about language, tone, humour, and all the quirks of human conversation.
Has AI ever passed the Turing Test?
The most famous early example came in 2014, when a chatbot called Eugene Goostman tricked several judges during an event at Reading University. Posing as a 13-year-old Ukrainian boy with slightly broken English, it convinced over a third of its human interrogators that it was real.
Was this the moment AI passed the Turing Test? Technically yes, but many researchers argue it was more of a clever dodge. By choosing the persona of a teenager whose English wasn’t perfect, the bot had a built-in excuse for mistakes. In other words, it passed by exploiting expectations rather than showing true intelligence.
Can ChatGPT pass the Turing Test?
Here’s where things get interesting. Tools like ChatGPT and other large language models have pushed conversation to new heights. They can handle everything from casual chit-chat to technical deep dives, often with humour and nuance that feels remarkably human.
And in early 2025, researchers at UC San Diego found that GPT-4.5 didn’t just come close—it passed a full, authentic Turing Test. In controlled trials with nearly 300 participants, GPT-4.5 convinced judges it was human 73% of the time—in fact, more often than actual human participants managed to do. The AI was most convincing when adopting a persona (for example, a shy young adult using slang), showing how subtle stylistic choices can tilt the balance toward believability.
So, could ChatGPT pass the Turing Test? Depending on which version you’re talking about, the answer is: yes, and in some cases, more convincingly than people themselves. That’s a milestone Alan Turing himself might have found rather astonishing.
When did AI pass the Turing Test?
The honest answer: there isn’t one clear date. Eugene Goostman’s “win” in 2014 was controversial. GPT-4 made progress but didn’t quite cross the line. GPT-4.5 in 2025, however, looks to be the most convincing case yet—a genuine moment where AI arguably achieved what Turing imagined.
Did you pass the Test?
Here’s the twist: the entire article you’ve just read (every explanation, every carefully chosen word, every turn of phrase) wasn’t written by a human at all. It was generated by AI.
So, did you spot it? Did you notice anything “off”? Or did you, like the judges in the GPT-4.5 trials, find yourself convinced by a machine?
That, in a way, is the Turing Test in action. It’s not just a question of whether AI can pass — it’s whether you, the reader, can tell the difference.
