An AI team named OpenAI Five that is being developed by OpenAI has defeated the champions of the 2018 Dota 2 International, team OG, in a best of three show match that was held in San Francisco over the weekend.
The match had used a custom set of restrictions, with human players having restrictions placed on what they are allowed to do, as the Open AI Five team lacks training in certain aspects of the game. A full list of the restrictions are available on the OpenAI website.
The OpenAI Five had won the match against team OG with a final score of 2-0, showing improvement from the previous show matches last year at The International 2018, where OpenAI Five faced off against and lost to paIN Gaming, a team that placed in the top 18 of the tournament. OpenAI Five had also lost to a team Chinese players from different teams.
After the event, OpenAI's chairman and corporate technology officer (CTO) Greg Brockman announced on Twitter that they are inviting Dota 2 players to play with and against OpenAI Five.
Development on OpenAI Five had initially begun back in 2016, with OpenAI choosing Dota 2 due to its popularity on videogame streaming website Twitch and because they felt that the game would be a good testbed for AI due to how it has elements of teamwork, long-term planning, and decision-making with limited information.
