OpenAI's Bots Defeated Former Pro E-Sports Players At Dota 2 (theverge.com)

On August 5th, OpenAI's bots defeated four former professional Dota 2 players in two of the three matches played. "There were a few conditions to make the game manageable for the AI, such as a narrower pool of 18 Dota heroes to choose from (instead of the full 100+) and item delivery couriers that are invincible," reports The Verge. "But those simplifications did little to detract from just how impressive an achievement [the] win was." From the report: The OpenAI Five triumphed in convincing fashion in the first game, not allowing the human players to even destroy one of their defensive towers. The humans recovered a little in game two, conquering one tower, but they still got demolished. And finally, in a game three played purely for pride, the humans managed to squeeze out a win. What stands out when you watch the matches is the apparent intelligence of the AI's decisions and the inhuman absence of any indecision. The typical Dota 2 game, even on the professional tier, involves quite a bit of equivocation about whether to engage in a fight, try and shift it to a more favorable battleground, or run away from it completely. The OpenAI team just doesn't need the processing time that humans require, which made its play appear unnatural -- but only in the speed and crispness of the decision-making, not in the content of those decisions.
