Computers Are Good at Computer Games: AI Wins Dota 2 1-on-1



GeekWire
has details on an AI demonstration at The International, where a
bot competed in a one-on-one demonstration versus a live pro player at the Dota 2
tournament. OpenAI project, a project
co-founded by SpaceX and Tesla CEO Elon Musk, brought an OpenAI-developed program
to play versus Danylo “Dendi” Ishutin, one of the MOBA’s top players.
This video shows off
the match, which did not go well for Dendi, and

GeekWire summarizes the action
, saying, “Ishutin was beaten badly in the
first match, forfeited a second match, and refused to play a third.” The
OpenAI blog has more details:

Today we played Dendi
on mainstage at The
International
, winning a best-of-three match. Over the past week, our bot
was undefeated against many top professionals including
SumaiL (top 1v1 player in
the world) and Arteezy
(top overall player in the world).

Dota 1v1 is a complex game with hidden information. Agents must learn to plan,
attack, trick, and deceive their opponents. The correlation between player skill
and actions-per-minute is not strong, and in fact, our AI’s actions-per-minute
are comparable to that of an average human player.

Success in Dota requires players to develop intuitions about their opponents and
plan accordingly. In the above video you can see that our bot has learned —
entirely via self-play — to predict where other players will move, to improvise
in response to unfamiliar situations, and how to influence the other player’s
allied units to help it succeed.

The full game of Dota is played by two teams of five. Each player chooses from a
hundred heroes and hundreds of items. Our next step is to create a team of Dota
2 bots which can compete and collaborate with the top human teams. If you’d like
