Artificial intelligence took a step forward last night, at an annual tournament for players of the tactical wargame Defense of the Ancients 2.
The MOBA is one of the most popular video games in all of competitive eSports, but no matter how good the best squishy humans are at the game, it seems OpenAI is better. Over the past week, our bot was undefeated against many top professionals including SumaiL (top 1v1 player in the world) and Arteezy (top overall player in the world). And rather than attempt a third round, Dendi surrendered.
Check out the gameplay the bot shows off - with players even saying that it plays in a very human-like manner.
The pro-grade Dota player was quite surprised as he got thrashed by the ruthless AI in two games which ultimately compelled him to cancel further matches.
"Our bot is trained entirely through self play".
Greg Brockman, himself, appeared to be impressed by the success of the method.
Dendi later elaborated on Twitter that he found the bot "fun" and "challenging" to play against. "This bot can learn from scratch in about two weeks of real time", Brockman said.
It's not only Google's AI that has the potential to defeat humans in their own game.
"They're pretty very bad", one player said.
There is no doubt that the milestone achieved by the bot is astonishing, however, what's particularly impressive about this feat is that winning in Dota requires players to have an intuition about what their opponents are thinking about doing and then build a corresponding game plan accordingly.
While bots have mastered games like Chess and Go, video games like DOTA 2 are still a challenge, but one that OpenAI seems equal to.
This isn't the first time a bot has made waves in the gaming world.
