"And now, we want to see how it stacks up against the best players in the world".
The Artificial Intelligence, as created by OpenAI, learned the gameplay all by itself, from the scratch.
In this footage from the Dota 2 International, Dendi - one of the world's best players - challenges OpenAI to a best of three competition. OpenAI stated that its AI had been performing at the championship and it has already defeated the Pakistan-based gamer Sumail (the world's best 1v1 player), and Arteezy (the world's overall top player).
The AI win stunned the gaming community, because bots are generally considered inferior to expert human players.
Dota 2, which is played by over 10 million people monthly is normally played between two teams of 5 players with the goal of collectively destroying a large structure defended by the opposing team known as the "Ancient", whilst defending their own. At a certain level, most pros are good enough to find strategies and weaknesses in the bot's play style that they can exploit and beat the bots easily.
Greg Brockman, Open AI co-founder and chief technology officer, explained the team's methods in a YouTube video posted Friday. You can build a pitching machine that throws ideal fastballs all day long, and probably a batting machine that hits them out of the park, but building a team of robotic baseball players is a completely different story. And rather than attempt a third round, Dendi surrendered. The full game is traditionally played 5v5.
The implications, of course, are that a bot that can master complex video games can have other uses too.
