In the past hour or so, an AI bot crushed a noted professional video games player at Dota 2 in a series of one-on-one showdowns.

The computer player was built, trained and optimized by OpenAI, Elon Musk's AI boffinry squad based in San Francisco, California. In a shock move on Friday evening, the software agent squared up to top Dota 2 pro gamer Dendi, a Ukrainian 27-year-old, at the Dota 2 world championships dubbed The International.

The OpenAI agent beat Dendi in less than 10 minutes in the first round, and trounced him again in a second round, securing victory in a best-of-three match. "This guy is scary," a shocked Dendi told the huge crowd watching the battle at the event. Musk was jubilant.

OpenAI first ever to defeat world's best players in competitive eSports. Vastly more complex than traditional board games like chess & Go.

According to OpenAI, its machine-learning bot was also able to pwn two other top human players this week: SumaiL and Arteezy. Although it's an impressive breakthrough, it's important to note this popular strategy game is usually played as a five-versus-five team game – a rather difficult environment for bots to handle.

[...] It's unclear exactly how OpenAI's bot was trained as the research outfit has not yet published any technical details. But a short blog post today describes a technique called "self-play" in which the agent started from scratch with no knowledge and was trained using supervised learning over a two-week period, repeatedly playing against itself. Its performance gets better over time as it continues to play the strategy game. It learns to predict its opponent's movements and pick which strategies are best in unfamiliar scenarios.

OpenAI said the next step is to create a team of Dota 2 bots that can compete or collaborate with human players in five-on-five matches. ®
