„A neural net chess engine that’s been specifically trained to play like a human of a given level would, by using online games of that level as the corpus“
In the past a „normal engine“ was either unbeatable or played somehow unnatural. This engine could be a gamechanger. What do you think?

I don't see any type of inspiration citation within the chess engine "makers". The only thanks i saw are for Lichess.
By the way @dkappe, i was wondering if there was a minimum hardware config for these elo-human-nets trained by maia projet to be reliable ? They don't seem to care about that in their paper (or May be I did not find that) .may be because the max elo is 1900 and that can easily achieved by Leela even on a pi 3 cpu ?

Yeah, Elo being a relative measure makes things tricky, we mention briefly in the paper that Leela is a different scale than Lichess. One of our hopes from having bots on Lichess is we'll get actual Elo ratings for our models

dkappe does some great stuff, his work on those small models is what we used as a starting point. I'll test against Bad Gyal when I have a chance. And if anyone else has models we should test against I'd love to hear it

Cheating online is going to become virtually undetectable. No need for using Stockfish for cheating, only a Maia trained to act like a GM or a strong IM, or for beating up low rated players, a Maia trained on players around 2000 elo.

On their homepage they write: „ In current work, we are pushing the modeling of human play to the next level: can we predict the moves a particular human player would make? It turns out that personalizing Maia gives us our biggest performance gains. We achieve these results by fine-tuning Maia: starting with a base Maia, say Maia 1900, we update the model by continuing training on an individual player’s games. This plot shows that personalized Maias achieve up to 75% accuracy at predicting particular players' moves.“
Image you take a certain chessplayer - his opening book - and 75 % accuracy by his moves!! Fascinating!!
The holy grail?

Not exactly. The reported accuracy was only a little over 50%.
