Humanity’s best Go player finally beat Google’s DeepMind computer for the first time
Go world champion Lee Sedol.
Google DeepMind’s AI was beaten by Go world champion Lee Sedol on Sunday in the fourth game of the Challenge Series tournament. That’s the first time that Sedol has managed to beat the computer.
Google DeepMind CEO Demis Hassabis tweeted that Sedol “was too good for us today and pressured #AlphaGo into a mistake that it couldn’t recover from.”
Although this is a big win for Sedol that proves DeepMind’s computer can be beaten, Sedol still can’t win the tournament. This is game four of a five-game series, and DeepMind won the previous three games.
Throughout the tournament DeepMind’s computer has made unusual moves that a human player typically wouldn’t consider. Some commentators have wondered whether they are mistakes, but usually they’ve just been unusual moves.
However, The Verge reports that the AlphaGo program made one unusual move in turn 79 of this game. Hassabis tweeted that the move was a genuine mistake, rather than a rare move:
Mistake was on move 79, but #AlphaGo only came to that realisation on around move 87

This won’t be the end of the tournament — there’s still one game left to play on Tuesday.
