Dota 2-Playing Robot Beats the Pros at The International

"We've created a bot which beats the world's top professionals at 1v1 matches of Dota 2 under standard tournament rules". While its actions per minute aren't any better than that of an average flesh-and-bone player, the choices make a huge difference.

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.

A bot created by OpenAI, an artificial intelligence startup backed by Tesla CEO and visionary Elon Musk, could be the new best DOTA 2 player in the world, as the world's top human players have so far been no match for it.


Open AI said the 1v1 bot has learned from playing against itself in lifetimes worth of matches.

The DOTA 2 AI faced off against Danil Ishutin, better known as Dendi and a popular name in the DOTA 2 eSports scene, at The International, the biggest annual tournament for the game.

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.


In a subsequent tweet Brockman mentions that OpenAI is now working towards Dota 5v5 and is hiring. Vastly more complex than traditional board games like chess & Go. A second round ended similarly, with Dendi surrendering after a few minutes. In a promo video shown before the match we see the bot besting some of the game's top players, including Evil Genius' cores Arteezy and Sumail. But after his defeat, Dendi said the bot "feels a little like [a] human, but a little like something else", too. The bot was trained by simply copying the AI and letting the two play each other for weeks on end.

"Would like to express our appreciation to Microsoft for use of their Azure cloud computing platform", he wrote.
