OpenAI's Dota 2 bot defeats world's best pro player

  • Бот в первый раз победил одного из лучших в мире игроков

The MOBA is one of the most popular video games in all of competitive eSports, but no matter how good the best squishy humans are at the game, it seems OpenAI is better.

OpenAI took the stage at the Dota 2 International Championship yesterday.

Dota 2 is normally played as a 5-vs-5 team game, so limiting the bot to a 1-on-1 match greatly reduces the complexity. Over the past week, our bot was undefeated against many top professionals including SumaiL (top 1v1 player in the world) and Arteezy (top overall player in the world).

In the live Shadow Fiend mirror match against Dendi, the bot executed an impossibly flawless creep block, perfectly balanced creep aggro, and even recognized and cancelled Dendi's healing items. OpenAI describes it as "a step towards building AI systems which accomplish well-defined goals in messy, complicated situations involving real humans".

Fundamentals in Focus for Healthcare Realty Trust Incorporated (HR)
UBS AG lowered Physicians Realty Trust from a strong-buy rating to an outperform rating in a research report on Monday, July 17th. BidaskClub upgraded Physicians Realty Trust from a hold rating to a buy rating in a research note on Friday, June 23rd.


In the best of 3 match, the AI was able to beat Dendi in less than 10 minutes. In the second match, the player surrendered themselves, and the third time refused to play by asking "complete mockery" of it.

Artificial Intelligence is now one topic, about which people are really divided and quite skeptical. "The correlation between player skill and actions-per-minute is not strong, and in fact, our AI's actions-per-minute are comparable to that of an average human player". "We didn't program it to understand the rules of Dota", says Greg from OpenAI, the team of researchers and engineers that developed the bot. Developers at the startup claim the AI learned to beat top Dota pros after just two weeks of real-time learning.
