AI beats top 'Dota 2' players in one-on-one matches

The result is an AI that not only has the fundamentals nailed down, but understands the nuances that take human players a long time to master. It's adept at tricks like zoning (preventing the enemy from hitting your creeps to deny them experience and gold) and raze faking (starting a raze animation to trick an enemy into dodging a non-existent attack). While its actions per minute aren't any better than that of an average flesh-and-bone player, the choices make a huge difference. And it doesn't take too long to learn, either; OpenAI's creation can beat regular Dota 2 bots after an hour of learning, and beat the best humans after just two weeks. Of course, these victories came about under controlled, ideal conditions.
