OpenAI Five Defeats Human Dota 2 Professionals Once Again

OpenAI Five defeated a world champion e-sports team in a competition dubbed as the "OpenAI Five Finals" at a packed event in San Francisco, California on April 13.

OpenAI previously demonstrated that it can defeat a professional Dota 2 player in a one-on-one match.

OpenAI is the research organisation behind the fully AI team and has spent the last four years working on an artificial intelligence that can replicate human-level skill in Valve's Dota 2.

Following the match, OpenAI has opened up sign-ups (for a limited period of time) to allow Dota 2 players to take the bot on for themselves, an opportunity that some AI-minded game devs might be interested in checking out.

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.

It is worth noting that OpenAI Five won the second match in just about 20 minutes - that is roughly half the first game's length.

"They are really great".

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 OpenAI team is releasing an online battle arena for the public to play against OpenAI. You can choose from competitive 5-on-5, co-op with friends, and single player co-op modes.
