In this situation, skill didn't really come into play as much, as the well-crafted lineup from the humans simply out-matched the poorly picked OpenAI, and it was the only victory that any group managed to take against them.
The bot technology of OpenAI has reached a point where it can now destroy a team of highly skilled, former professional, Dota 2 players - in a match that wasn't even close.
After the game 1 draft, OpenAI Five predicted a 95% win probability, even though the matchup seemed about even to the human observers.
After winning the first two games comprehensively, the OpenAI allowed the audience to pick five human players to compete in the dead rubber match which it lost. OpenAI has also been tweaking the neural networks, altering the bot team's in-game reaction time to near-human levels, and helping it learn additional strategies.
And the OpenAI has the advantage of learning through rigorous reinforcement training, a machine learning technique that involves teaching AI agents through trial and error and then "rewarding" them when they carry out a good action in the game.
According to Greg Brockman, a co-founder of OpenAI, the company is working on designing bots that can beat elite human gamers because the simulated battle experience in Dota is so multi-faceted that it begins to approximate the chaos of the real world.
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. In preparation the bots played through 180 years' worth of games against each other every day. The International tournament of the game is going to take place from August 20 to 25. However, the show's still going on Twitch with OpenAI explaining more about how they built and tested their team, and what's next for them.
For those who don't know, OpenAI is a non-profit organization founded by Elon Musk.
