22 AI levels, from 18 kyu to amateur 4 dan
Go AI's weaker levels do not just play slightly worse. They make the kind of mistakes a real player at that rank makes, so every game stays honest and instructive.
What kyu and dan mean
Go ranks count down through the kyu grades, so 18 kyu is a beginner rank and 1 kyu is the strongest kyu grade. After that, amateur ranks count up through dan: 1 dan, 2 dan and so on.
Human SL playing styles
Go AI includes KataGo's Human SL model, which learned from human games, in three styles: modern, traditional and varied.
Game settings
Play on 9×9, 13×13 or 19×19 with Chinese rules and adjustable komi. Undo, pass, resign and move hints are always available.
Review every game
Step through any finished game move by move with a win-rate graph, see where the game turned, and check the top candidate moves at any point.
