Very curious how this is going to turn out... This sounds like they are trying to train a bot to actually not be perfect? Otherwise I think they would say straight out: "You'll only have the option if you are grand-master". Since they don't say that, it feels like they are probably training the bot to "play like it's at Gold League" etc.
If it could make the same types of mistakes and overlook things in the same way a human would, that would be very interesting for game creators. Most game creators would tell you: usually the hard thing is not making a good AI, but making an AI that is fun, but still loses. We've all seen that AI can usually just win any game, if you give it enough juice.

(At least part of) The training has MMR as a label from unsupervised learning from human games so as part of the configuration they can set the agent to play like someone with a set MMR.
Lex Fridman's interview with Oriol Vinyalis on Lex's AI podcast covers this in more depth.
