Dota 2 : 'Artificial intelligence' makes a record by defeating human players


OpenAI Five, the Dota 2 team (of bots) played against semi-professional players who were reportedly ranked in the 99.95th percentile in the world.

There's no doubt that the popularity of MMORPGs such as Dota 2 is steadily on the rise, especially with the game having been linked to events such as the Olympic Council of Asia's announcement that eSports will be made an official medal sport at the upcoming 2022 Asian Games in Hangzhou, China.

The blog added, "We've increased the reaction time of OpenAI Five from 80ms to 200ms".

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 research initiative co-founded by Elon Musk has successfully trained AI bots to trounce professional human players of the popular arena battle game Dota 2, a big step up from the bots in June being good enough to beat casual players.

The team which won the exhibition match is named OpenAI Five, and comprises a team of five bots.

In order to make the game manageable for AI bots, the game was tweaked a bit.

Open AI, an artificial intelligence research firm funded by Elon Musk, raised many impressed eyebrows this week when a team of AI bots created by them defeated human players in the popular online multiplayer video game Dota 2.

The Verge goes on to report that one of the things that was particularly impressive in the match-up from the AI perspective is its "inhuman" lack of indecision.

Dota 2 is available now for PC, Mac, and Linux. "You have imperfect information, you have team work, you have these exponential combinations of different heroes and items, and you have to be able to deal with all of that". Without the ability to build a team it knew how to play, the AI was at a disadvantage.

To rack up enough training and the requisite knowledge that comes with it, OpenAI's bots played what amounts to 180 years' worth of games against themselves every day. The best gamers in the world are machines.
