43 AI Performance = Increasingly Realistic Conversations Simulating Human Behaviors Turing Test Conversation with GPT-4.5 – 3/25, per Cameron Jones / Benjamin Bergen Source: Cameron Jones and Benjamin Bergen, ‘Large Language Models Pass the Turing Test’ (3/25) via UC San Diego What Was Tested: The Turing Test is a concept introduced by Alan Turing in 1950 to evaluate a machine’s ability to exhibit intelligent behavior indistinguishable from that of a human. In the test, if a human evaluator cannot reliably tell whether responses are coming from a human or a machine during a conversation, the machine is said to have passed. Here, participants had to guess whether Witness A or Witness B was an AI system. Results: The conversation on the left is an example Turing Test carried out in 3/25 using GPT-4.5. During the test, participants incorrectly identified the left image (Witness A) as human with 87% certainty, saying ‘A had human vibes. B had human imitation vibes.’ A was actually AI-generated; B was human. AI Development Trending = Unprecedented
