Watch pro Dota 2 players take on an AI team

Reigning Dota 2 world champions, OG went up against a virtual AI team in San Francisco this past weekend.

For those unaware, OpenAI Five is a team of OpenAI-curated bots developed by OpenAI, a research institute co-founded by Tesla CEO, Elon Musk, to develop and research human-level artificial intelligence. OpenAI Five lost out at last years World Championships where it failed to defeat the two pro teams it was put up against.

Given that Dota 2 is a complex strategy game which involves multiple characters, screens, and options along with a huge number of variables, it makes a good test bed for AI. In a best-of-three game, the OpenAI Five won 2-0. However, it was not the same case for the OpenAI bots past year, where they were defeated twice by human professional players at the Dota 2 International Tournament (Ti8) in Vancouver.

"They are really great". The matches were played in Captain's Draft mode, where each team can ban characters to prevent the other from selecting them.

DNA test confirms killing of leader of ISIS-affiliated group in Philippines
It was hard to determine Marohombsar's identity by face because one of the bodies "was deformed", Brawner said. Most leaders of the attack were killed, but Marohombsar survived.

Looks like OpenAI has learned a lot from their defeats at Ti8 past year.

That represents a monumental achievement in designing a system that can upskill itself with a technique called deep reinforcement learning, wherein a bot isn't taught how to play, but rather how to learn to master the game by figuring out which of its actions bring rewards.

The Verge reports that the team behind OpenAI Five is wrapping up public demonstrations of the system's capabilities, and is moving on to building software to allow humans to collaborate with the neural networks in the game.
