GPT‑4.5 Passes the Turing Test: A New Milestone in Human‑Like AI
In a new study from UC San Diego’s Language and Cognition Lab, OpenAI’s GPT‑4.5 was able to convince people it was human in 73% of short text conversations—when it was given a detailed human-like persona to follow. Each conversation lasted five minutes, and the AI was chosen as the human more often than the actual human participant. The experiment was based on a modern version of the Turing Test—a method from 1950 that checks if a machine can talk like a person well enough to fool someone. This result shows how far conversational AI has come, especially when it’s guided to behave in a more personal, human way. Researchers also […]
