OpenAI built gaming bots that can work as a team with inhuman precision

When humans and artificial intelligence face off in a game, like chess or Go, it's typically a one-against-one affair. Each player, human or AI, just has to outsmart a single opponent on a board that only changes when the players make a move. OpenAI is announcing today (June 25) that its newest AI bots can hold their own as a team of five against human gamers at Dota 2, a multiplayer game popular in e-sports for its complexity and necessity for teamwork. The AI research lab is looking to take the bots to Dota 2 championship matches in August to compete against the pros. Dota 2 is a challenging game for AI to master simply because of the amount of decisions that the players have to juggle. While chess can end in fewer than 40 moves, and Go fewer than 150, OpenAI's Dota 2 bots make 20,000 moves over the course of a 45 minute game.
