A bot just defeated one of the world's best video gamers


To test out some harmless uses for AI, one Open AI team taught a bot to play Dota 2. Musk thanked the company via Twitter for allowing Open AI to use the Microsoft Azure crowd computing platform to develop the bot. Would like to express our appreciation to Microsoft for use of their Azure cloud computing platform.

AI beats top 'Dota 2' players in one-on-one matches


The Elon Musk-backed OpenAI team has developed a machine learning system that has beaten "many" of the best pro Dota 2 players in one-on-one matches, including star player Dendi during a live demonstration at The International. The result is an AI that not only has the fundamentals nailed down, but understands the nuances that take human players a long time to master. And it doesn't take too long to learn, either; OpenAI's creation can beat regular Dota 2 bots after an hour of learning, and beat the best humans after just two weeks. One-on-one matches are far less complex than standard five-on-five matches, and it's notable that the machine learning system doesn't use the full range of tactics you see from human rivals.

The world's best Dota 2 players just got destroyed by a killer AI from Elon Musk's startup


Tonight during Valve's yearly Dota 2 tournament, a surprise segment introduced what could be the best new player in the world -- a bot from Elon Musk-backed startup OpenAI. Engineers from the nonprofit say the bot learned enough to beat Dota 2 pros in just two weeks of real-time learning, though in that training period they say it amassed "lifetimes" of experience, likely using a neural network judging by the company's prior efforts. Dota 2 is an astoundingly complex game in which two teams of 5 players compete to siege and destroy the opposing team's base. Elon Musk founded OpenAI as a nonprofit venture to prevent AI from destroying the world -- something Musk has been beating the drum about for years.

The basic moves: A game of dota usually has around 200-300 actions per minute from a pro-player. Those actions can be movement orders, spells, attack orders. It is very hard to determine the utility of move, given that it is tradeoff between damage done, damage taken, minions killed, lane equilibrium changed, mana & cooldowns expended. Even if bot is able to make optimal decisions around every 0.25 seconds which is inline with the number of moves of a pro player, many of a pro player's moves are wasteful and I suspect the actual decision rate of a player to be lower.
