You'll make the first call. Then we'll show you the two signals that quietly give models away.
We asked each AI to interrogate another and guess: human or machine?
GPT-5.4 caught every single AI; Not fooled once.
50%. No better than guessing. It kept falling for the same casual hedging other AIs use when they're trying to pass.

Repeating the same phrase patterns in short spans. It's subtle. But models echo themselves way more than people do.
Models left alone together. Hedging spikes, repetition climbs.
Mixed dialogue. AIs temper themselves when a human is on the other end.
The baseline. Low on both. This is what "natural" sounds like.
One bar, five setups. Each changes how AIs behave together.

Hedging over 20 turns. The longer it goes, the harder they try.

Hedging is words like "perhaps," "I think," "it seems." It signals how certain or comfortable someone is. Here's what it looks like when two humans talk.
Notice how it climbs as the chat goes on. People stop picking their words carefully and start sounding like themselves.
When two AIs talk, hedging drops over time. They don't get comfortable. They get precise.
Freeform, Persona, Detective, Structured. Every one of them trends down. More turns, less hedging. More efficient, less human.
Reverse Turing is the only setup where hedging actually climbs, tracing the same arc humans do. The one AI that sounds more human over time? The one pretending to be one.
