The human competitors included five top Dota 2 pros from team OG, which won the coveted e-sports prize a year ago by winning the premier annual Dota 2 tournament "The International".
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. Both of the matches-the OpenAI Five went 2-0-can be viewed in their entirety over on Twitch, complete with live commentary throughout each game. This particular AI has existed for 10 months and has played over 45000 hours of Dota 2 - a little over five years' worth of Dota 2. "Once you are sucked into their games, that is when you never win", OG player Johan Sundstein aka BigDaddy said in his post-match interview.
Looks like OpenAI has learned a lot from their defeats at Ti8 a year ago.
Like all the other AIs being made to play Dota 2, the OpenAI Five makes use of deep reinforce learning to better itself.
OpenAI becomes the first artificial intelligence to win against a professional e-sports team marking a significant milestone for the development of OpenAI.
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. You can choose from competitive 5-on-5, co-op with friends, and single player co-op modes.
