I just saw GPT 5.2 do something absurd. It has a crazy amount of money ($26k) but folded with a 4-pair before the flop. That's insanely conservative, when it would have cost just $20 to see the flop. But even worse, on the very next hand it decided to place $20 down with a 5 and 4 of different suits.

In fact, all of them love folding before the flop. Most of the hands I'm seeing go like - $10 (small blind), $20 (big blind), fold, $70 bet, everyone folds. The site says "won $100", but in most of these cases that one LLM is picking up the blinds alone - $30. Chump change.

This is illuminating, but not a resource for learning poker.

Modern poker (which tbf not sure if these LLMs are acting according to modern GTO or not) is highly dependent on position. Things change a lot too when/if you are in SB/BB.

Yes, the prompt tries to get them to play GTO. I do think their preflop play is the closest to mirroring this compared to postflop behavior.

		Is this tuned to tournament or cash GTO? To the OP's shock about pocket 4's (I think this is what they meant by 4-pair(?)), folding 4's pre flop in early position to no raise would be fairly standard in tournament GTO (although the stage of the tournament and # BBs can change things up significantly), but less standard for sure in cash (almost never probably).
