And it wasn't even close.

A month and a half ago, OpenAI showed off the latest iteration of its Dota 2 bots, which had matured to the point of playing and winning a full five-on-five game against human opponents. Those artificial intelligence agents learned everything by themselves, exploring and experimenting on the complex Dota playing field at a learning rate of 180 years per day. [...] the so-called OpenAI Five truly earned their credibility by defeating a team of four pro players and one Dota 2 commentator in a best-of-three series of games.

There were a few conditions to make the game manageable for the AI, such as a narrower pool of 18 Dota heroes to choose from (instead of the full 100+) and item delivery couriers that are invincible. But those simplifications did little to detract from just how impressive an achievement today's win was.

[...] play-by-play commentator Austin "Capitalist" Walsh sums up the despondency felt by Team Human after the bout neatly:

Never felt more useless in my life but we're having fun at least so I think we're winning in spirit.

Sure aren't winning in-game
