Elite Dota 2 Team Easily Beat by Advanced AI Bots

Elite Dota 2 Team Easily Beat by Advanced AI Bots

A bot from OpenAI was taught to play Dota 2 with the help of machine learning, and it beat the world-famous Danil "Dendi" Ishutin in a one-on-one match at The International 2017. The second match saw the pro team take out one of OpenAI's towers, but the AI group won regardless.

Original story: Research institute OpenAI, which Elon Musk co-founded in 2015, is set to send its super-smart self-taught Dota 2 bots to The International 2018 later this month to take on a team of experienced pros.

Since OpenAI's Dota 2 bot beat professional player Danylo "Dendi" Ishutin at the global 2017, the AI has evolved significantly.

Every member of Team Human were selected on the criteria of being within the 99th percentile of players, which makes sense considering that a lot of them used to be active pro players. Game Two was similarly one-sided, although the humans did manage to at least take one tower.

According to Greg Brockman, a co-founder of OpenAI, the company is working on designing bots that can beat elite human gamers because the simulated battle experience in Dota is so multi-faceted that it begins to approximate the chaos of the real world. Reward functions were identified, where the bots score points when they accomplish a certain task, but other than that they're basically set loose to play themselves. The team of former professional players and commentators was said to have ranked in the 99.95th percentile in the world. These are all people who now or previously play Dota 2 professionally - they're in the 99.95th percentile of human players. This resulted in the bot predicting a lower chance of winning of the match. OpenAI is scheduled to face an active professional squad at The International 8, which kicks off on August 15.

Ahead of the three-game battle, OpenAI in a blog post explained, "Because our training system Rapid is very general, we were able to teach OpenAI Five many complex skills since June simply by integrating new features and randomizations". Well, the AI platform developed by OpenAI would like to have a word, humans.
