I recently tried it on Deck and it’s rough, but I think a lot of people only have a deck as an option to play it, so they use what they have. It’s a fun game, so it makes sense. If you have the option to play on a PC, it’s not worth using your steam deck though.
o1 preview is insane really, it even corrects you when you ask a question poorly, or rather, it talks around your mistakes.
