I had a similar disc with one of my friends! Anthropic is bragging that the model was not trained to play pokemon, but pokemon red has massive wikis for speed running that based on the reasoning traces are clearly in the training data. Like the model trace said it was "training a nidoran to level 12 b.c. at level 12 nidoran learns double kick which will help against brock's rock type pokemon", so it's not going totally blind in the game. There was also a couple outputs when it got stuck for several hours where it started printing things like "Based on the hint..." which seemed kind of sus. I wouldn't be surprised if it there is some additional hand holding going on in the back based on the game state (i.e., go to oaks, get a starter, go north to viridian, etc.) that help guide the model. In fact, I'd be surprised if this wasn't the case.

One more tidbit, I checked in and it's been stuck in Mt Moon first floor for 6 hours. Just out of curiosity, I asked an OAI model "what do I do if im stuck in mount moon 1F" and it spit a step-by-step guide how to navigate the cave with the location of each exit and what to look for, so yeah, even without someone hardcoding hints in the model, just knowing the game state and querying what's next suffices to get the next step to progress the game.
