Elon Musk's AI bot beats world-class gamers at Dota 2

Elon Musk's AI bot beats world-class gamers at Dota 2

The bot crushed its opponents, displaying a level of mechanical skill that is usually expected from humans.

The reason Dota 1v1 is considered a complex game is because the players must learn to plan, attack, trick, and deceive their opponents.

Today we played Dendi on mainstage at The International, winning a best-of-three match. The ten players each control one of the game's 113 "heroes" each of which have their own strengths and weaknesses. The bot learned to play the game only by playing against itself. The prize? A free Shadow Fiend arcana.

The full game of Dota is played by two teams of five. 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).

In a subsequent tweet Brockman mentions that OpenAI is now working towards Dota 5v5 and is hiring. And rather than attempt a third round, Dendi surrendered. "This guy is really scary", Dendi kept saying, and at one point yelped "Please stop bullying me!" when the bot rushed at him aggressively.

The OpenAI bot appears to run off a modified version of a genetic machine learning algorithm, meaning it evolves and learns as it plays and discards inferior versions of its code (the company wasn't specific with its language, but a programmer friend of mine who also plays Dota said it sounded like a genetic algorithm).

The bot was also taking challenges from random players at the venue, accordingto Dota 2 journalist Victoria "riningear" Rose.

A video introduction for the bot showed various (human) Dota 2 players sharing their opinions on bots. It quickly began to implement research projects, see OpenAI Gym Gives Reinforcement Learning A Work Out and previous year partnered with Microsoft in order to use Azure.
