After DeepMind's ascent to the top of Go playing, and with great advances in AI systems playing many (but not some other) Atari games through self-training and reinforcement learning, interest has turned to games that require a lot of long-term strategic thinking and sub-goal setting, such as Starcraft 2 and in the short-term, Dota 2.
OpenAI's Dota 2 player system has been defeating top humans in 1-on-1 play for about a year, and OpenAI has recently announced that its Dota2-playing system had begun to beat skilled human teams on 5-on-5 team play, a significantly larger challenge.
OpenAI now feels ready for the big-time, and will enter its 5-player system in "The International", a major Dota 2 championshop with a $20M purse. There's a site set up for this and everything.
Will OpenAI's system beat the top players on August 5th?
The question accepts whatever rules/restrictions the match occurs under. If there is a single game, resolution will be based on that game. If there are multiple games it will be based on winning the majority of the games; in case of a tie it resolves ambiguous.
A sister question will concern "The International" once more details become available.
