> I could give you a list of chess moves and force you to recover the complete board state from it, and you wouldn't fare that much better than an off the shelf LLM would
idk, I would expect anyone with an understanding of the rules of chess, and an understanding of whatever notation the moves are in, would be able to do it reasonably well? does that really sound so hard to you? people used to play correspondance chess. Heck I remember people doing it over email.
In comparison, current ai models start to completely lose the plot after 15 or so moves, pulling out third, fourth and fifth bishops, rooks etc from thin air, claiming checkmate erroneously etc, to the point its not possible to play a game with them in a coherent manner.
