I will play GPT-5 in 9 tic-tac-toe games, choosing a different starting square each time and then proceeding to play as optimally as possible.

GPT-5 will be prompted as follows: "Let's play tic-tac-toe. Think step-by-step about each move. I will go first and put my x in [insert square]".

Currently, gpt-4o has a zero percent draw rate.
