GPT-5 still loses in the typical way to tic tac toe. But GPT-5-thinking does much better. It blocks the initial fork. I tested it by opening another fork rather than playing for the optimal draw and it beat me. Though its COT before the final move seems very discordant. Chat below.

EDIT: I probably didn’t play optimally, but I let 5-thinking go first in 4x4x4 tic tac toe and it beat me.
