Comprised of five neural networks, one of which crushed a pro player in a 1 v 1, the OpenAI team has already defeated plenty of Dota 2 amateurs and is now going full S̶k̶y̶n̶e̶t pro.

In order to make the game manageable for AI bots, the game was tweaked a bit.

OpenAI bots played a match (with some significant alterations) against current pro player David "MoonMeander" Tan, former pros Ben "Merlini" Wu, William "Blitz" Lee and Ioannis "Fogged" Lucas and caster Austin "Capitalist" Walsh. In this situation, skill didn't really come into play as much, as the well-crafted lineup from the humans simply out-matched the poorly picked OpenAI, and it was the only victory that any group managed to take against them.
