AI Obliterates Semi-Professional Dota 2 Players In A Game

OpenAI's team of AI-powered Dota 2 bots have reached yet another impressive milestone - it was able to beat the five veteran players in a 3-on-3 match, dominating two rounds before being defeated narrowly in the third match.

OpenAI's 1v1 bot beat pro player Danil "Dendi" Ishutin at last year's The International, and the institute says the learning process for OpenAI Five is much more complex, requiring 256 GPUs and 128,000 CPU cores. The team of former professional players and commentators was said to have ranked in the 99.95th percentile in the world. Next step, is The International 2018 (T18), which is Valve's own Dota 2 major and considered one of the biggest e-sports tournaments in the world. The Dota 2 pros fought harder in the second round and managed to destroy one of the OpenAI Five's towers, but they ultimately had to admit defeat to the bots. The humans recovered a little in game two, conquering one tower, but still getting demolished.

Every member of Team Human were selected on the criteria of being within the 99th percentile of players, which makes sense considering that majority used to be active pro players.




The humans won the final game, but only after the audience was allowed to select the bots' player characters, which put them at a significant advantage. There were some restrictions on this five-on-five match - namely, the teams could only use 18 of Dota 2's 115 heroes - but the bots were still good enough to prove that humanity is doomed.

OpenAI's initiatives with Dota 2 began in March previous year. The team of bots calculated a 2.9% chance of winning before the start of the game based on its heroes' lineup. The bot has around 10,000 hours of Dota 2 playtime, which it uses to formulate advanced strategies that pro teams employ, according to the OpenAI organization. Apparently, the five-on-five bot team has been in development all year, but this was the first true competition against real professionals.

However, the show's still going on Twitch with OpenAI explaining more about how they built and tested their team, and what's next for them.
