First computer to beat a Dota 2 world champion under standard tournament rules

On 10 August 2017, a bot created by AI research company OpenAI, won a 1-vs-1 match of Valve's MOBA Dota 2 against 2015's The International champion Sumail "SumaiL" Hassan (Pakistan), playing under standard tournament rules. The match took place in a private Valve lounge in Seattle Key Arena, USA, during The International 2017 tournament – effectively the "World Cup" of Dota 2. The same version of the bot defeated 2011 The International champion "Dendi" the following day on the main stage. Earlier versions of the bot had also previously beaten fellow Dota 2 pros "Arteezy", "Pajkatt" and "CC&C". OpenAI wrote: “Our Dota 2 result shows that self-play can catapult the performance of machine learning systems from far below human level to superhuman, given sufficient compute. In the span of a month, our system went from barely matching a high-ranked player to beating the top pros and has continued to improve since then."

Sumail "SumaiL" Hassan won The International 2015 as part of the eSports team Evil Geniuses and became the youngest eSports star to earn $1 million in winnings. The match against the bot was played in the 1-vs-1 mid mode. The standard tournament rules include: - no bottle - no runes - no shrines - no jungling - no Soul Ring - no Infused Raindrop.

The objective is to kill the enemy player twice or destroy their mid tower. If the game clock goes past 10:00, the winner is the player with more kills, with ties decided by number of last hits + denies.
