Geoguesser was already a solved problem. I guarantee you ChatGPT is much worse than current systems designed to play Geoguesser (NMPZ).

Chatbots appear to have some amount of fluid intellgence so they can do impressive tasks with this information, the impressiveness of these tasks will likely increase in the future. But for simply getting a good score on Geoguesser it's not even close to hobby projects let alone state of the art.
