Pretty progress graph here lczero.org. This project has started recently, based on google's alphazero paper. There is a cpu only contribute method, but GPUs are several times faster. Progress just really started today with learning on the self play games being automated, but it has been gaining +100 elo a day, so it is just now a decent club player with a little bit of time per move.
