AI Obliterates Semi-Professional Dota 2 Players In A Game

The team of former professional players and commentators was said to have ranked in the 99.95th percentile in the world.

The bots have only gotten better from there, sharpening their game-playing skills even to the point of being able to crush players who've been competing at Dota 2 since its beginning.

In front of 100,000 live-streamers, the bot team easily took out the best-of-three tournament, winning the first game in 21.5 minutes and the second in just under 25 (evenly matched games generally take around 45 minutes). "The typical Dota 2 game, even on the professional tier, involves quite a bit of equivocation about whether to engage in a fight, or whether to try to shift it to a more favorable battleground, or to run away from it completely". The list of handicaps included the ability to pick only 18 of the 115 available heroes in the pool, while Team Human was given freedom to use any hero of their choosing.

A team of ex-pro Dota 2 players and casters were soundly beaten by OpenAI's team of bots in a best-of-three exhibition match.

OpenAI, which has been in development as a Dota 2 bot since The International 7 a year ago, went up against a full team of five highly-skilled human players-composed of Ioannis "Fogged" Loucas, William "Blitz" Lee, Ben "Merlini" Wu, David "MoonMeander" Tan, and Austin "Capitalist" Walsh. Heroes in Dota 2 often interact in complex ways. The characters Open AI played were selected by Twitch users, giving Team Human a slight advantage.

While OpenAI's defeat of some of Dota 2's cream of the crop players is decidedly impressive, what's definitely more noteworthy is the unprecedented advancement of artificial intelligence itself. Even the, AlphaZero achieved a superhuman level of play in the games of chess, shogi and Go within 24 hours.

OpenAI Five will take on an active professional team during the worldwide main event in August 2018. Last month, the company released footage of a robotic arm manipulating a cube with uncanny dexterity that was trained using reinforcement learning algorithm as the OpenAI Five.
