Update on Claude playing Pokémon: Fable beat Pokémon FireRed with a vision-only harness in just over 50 hours. That's an hour faster than a heavily-harnessed GPT 5.5 beat FireRed, and >6x faster than the 325 hours it took a lightly-harnessed Opus 4.7 to beat Pokémon Red. (For comparison, an average human would take about 30 hours for FireRed and 26 hours for Red.)
Unfortunately no full stream has been provided, just two short, edited videos, one of which was quickly taken down. Some analysis of the videos can be found here - for the first time there's some reason for suspicion that previous runs made it into the training data, though there isn't enough info to be confident either way.
I think previous runs in the training data isn't a big deal. There's already a ton of game guides and discussion in the training data and the models know the general route / puzzle solutions if you ask
