OpenAI Crosses Out Restrictions For Dota 2 Bots - Tipify

Esports News – Non-profit, artificial-intelligence research company OpenAI recently announced that their new robots are capable of playing Dota 2 5-on-5 matches. OpenAI is prepared to feature their groundbreaking creation on The International 2018 (TI8) to “beat a team of top professionals”. The initial announcement established certain restrictions on both bots and human opponents, including the absence of warding, Roshan, invisibility, summons or illusions, and scan. But now, the organization has deemed it necessary to remove tight restrictions and let the bots move closer to human-level skill.

New terms and conditions

The exciting news was posted on the company’s OpenAI Five Benchmark website. It turns out that they are still training and improving their bots following announcement and prior to the official TI8. OpenAI explained in a blog post: “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. Many people pointed out that wards and Roshan were particularly important to include—and now we’ve done so. We’ve also increased the hero pool to 18 heroes. Many commenters thought these improvements would take another year. We’ll see how well these new game mechanics work on August 5th.”

There will be a pool of 18 heroes for the human players. Instead of a Mirror Match among 5 champions, they can now control Axe, Crystal Maiden, Death Prophet, Earthshaker, Gyrocopter, Lich, Lion, Necrophos, Queen of Pain, Razor, Riki, Shadow Fiend, Slark, Sniper, Sven, Tidehunter, Viper, or Witch Doctor. Adding to the list of new characters is the inclusion of new techniques and items; the following are no longer restricted: warding, Roshan, invisibility, Quelling Blade, Boots of Travel, Tome of Knowledge, and Infused Raindrop.

To further achieve a human-level skill, OpenAI also increased the reaction time of the five bots from 80ms to 200ms. This is clearly much closer to human-level, but the witnesses involved during the training have yet to see changes in gameplay as the bots’ strength are still based on teamwork and coordination than reflexes.

TI8 event schedule

The official date for the match is August 5th, and will culminate as follows:

  • 12 pm PT: doors open
  • 12:30 pm PT: official live stream begins with interactive games for the audience
  • 2 pm PT: best-of-three matches versus 99.95th percentile Dota 2 players
