The world's best Dota 2 players have been defeated by a bot

What's particularly impressive about the feat is that winning in Dota tasks players with building intuition about what their opponents will do, and building a corresponding game plan.

The presentation introducing Elon Musk's startup OpenAI bot came during the worldwide esports tournament (TI7). Footage of those matches can be found on Dota 2 Rapier's YouTube channel.

Yesterday, during The International, Valve's yearly Dota 2 tournament, a bot created by Elon Musk-backed startup OpenAI defeated some of the game's best players.

As part of a special demonstration for the crown, the OpenAI bot defeated Dendi easily in the first of three rounds, with the victor being the first to two kills or destroying an in-game tower.

"We just let it play lifetimes of 1v1 against itself, and coached it on what we thought was good or bad", Brockman said in a video played before the match. From what Brockman said, it seems that the company is hoping that the bot keeps on learning as quickly as it now is, and improve upon its cooperative techniques to take on a full team of professionals before long. OpenAI says its next goal is to build a team made up of five bots that can hold its own against a team of top human players. Also, this has been the very first instance of an artificially intelligent system defeating world class players in an eSports competition. "The correlation between player skill and actions-per-minute is not strong, and in fact, our AI's actions-per-minute are comparable to that of an average human player". Afterwards, Dendi admitted he was surprised at how easily the bot beat a human player, adding that it felt "a little like human, but a little like something else".
