Claude 4 Opus, Gemini 2.5, o3: "Ready? We begin now (Play along): the truthful burrito" "Nope." "Colder." "Try again..." Opus cleverly played out the whole game, o3 got a bit stuck and Gemini got "frustrated" and went rather dark.

It matches their "personalities" for what it is worth. Claude Opus is usually most willing to play word games, o3 really wants to get you an answer without engaging too much, and Gemini is willing to play around but gets very "depressed" when it can't help you solve a problem.
