The bot by OpenAI demonstrated its skills at the annual live tournament "The International" this past weekend. It was up against a crowd favorite, the pro player "Dendi" who is one of the best in the world when it comes to Dota 2. He was defeated by the bot twice, before forfeiting any more future matches. After the game, Dendi stated that the bot "feels a little like [a] human, but a little like something else." - many of its moves looked familiar and human. He was surprised that it was possible for the AI machine to beat a human player - and therefore human intelligence. 'Bot is really fun and challenging to play against.

By Cade Metz SAN FRANCISCO: At OpenAI, the artificial intelligence lab founded by Tesla's chief executive, Elon Musk, machines are teaching themselves to behave like humans. But sometimes, this goes wrong. Sitting inside OpenAI's San Francisco offices on a recent afternoon, the researcher Dario Amodei showed off an autonomous system that taught itself to play Coast Runners, an old boat-racing video game. The winner is the boat with the most points that also crosses the finish line. The result was surprising: The boat was far too interested in the little green widgets that popped up on the screen.

For decades, the world's smartest game-playing humans have been racking up losses to increasingly sophisticated forms of artificial intelligence. The defeats began in the 1990s when IBM's Deep Blue computer conquered chess master Garry Kasparov. More recently, Ke Jie -- until then the world's best player of the ancient Chinese board game "Go" -- was defeated by a Google computer program in May. Now the AI supergamers have moved into the world of e-sports. Last week, an artificial intelligence bot created by the Elon Musk-backed start-up OpenAI defeated some of the world's most talented players of Dota 2, a fast-paced, highly complex, multiplayer online video game that draws fierce competition from all over the globe.

You might not have noticed, but over the weekend a little coup took place. On Friday night, in front of a crowd of thousands, an AI bot beat a professional human player at Dota 2 -- one of the world's most popular video games. The human champ, the affable Danil "Dendi" Ishutin, threw in the towel after being killed three times, saying he couldn't beat the unstoppable bot. "It feels a little bit like human," said Dendi. The bot's patron was none other than tech billionaire Elon Musk, who helped found and fund the institution that designed it, OpenAI.

Today we played Dendi on mainstage at The International, winning a best-of-three match. 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). Dota 1v1 is a complex game with hidden information. Agents must learn to plan, attack, trick, and deceive their opponents. 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.

Elon Musk is a hype merchant, and this weekend his Twitter account served up a generous serving of hoopla for the OpenAI bots that were destroying the best Dota 2 players in the world. As a veteran Dota player and inveterate contrarian, I couldn't let Musk's exaggeration go by unchallenged. What we saw the OpenAI bots achieve was awe-inspiring for anyone who's ever dabbled in Dota, but it's still only scratching the surface of the competitive complexity of this game. OpenAI first ever to defeat world's best players in competitive eSports. Vastly more complex than traditional board games like chess & Go.

Elon Musk has warned again about the dangers of artificial intelligence, saying that it poses "vastly more risk" than the apparent nuclear capabilities of North Korea does. The Tesla and SpaceX chief executive took to Twitter to once again reiterate the need for concern around the development of AI, following the victory of Musk-led AI development over professional players of the Dota 2 online multiplayer battle game. If you're not concerned about AI safety, you should be. This is not the first time Musk has stated that AI could potentially be one of the most dangerous international developments. He said in October 2014 that he considered it humanity's "biggest existential threat", a view he has repeated several times while making investments in AI startups and organisations, including OpenAI, to "keep an eye on what's going on".

Catching these widgets meant scoring points.

Some of the most revolutionary advances in artificial intelligence are coming from the world of video games. The OpenAI team, supported by tech maven Elon Musk, showcased an AI bot at a tournament in Seattle that decisively beat several of the world's best Dota 2 players in one-on-one matches. The stunning upset over pro gamer and crowd favorite Danylo "Dendi" Isutin was broadcast live from the stage at The International, a $24 million Dota 2 tournament backed by Valve. In the first match, the machine-learning algorithm defeated Dendi in ten minutes. Dendi then resigned from the second match, and declined a third.
