Watch OpenAI Bots Destroy Top Human Players in Dota 2

  • Watch OpenAI's Dota 2 bots square off against five top players live on Twitch today

The humans fared much better in the second match as they used tricks to confuse the bots, but a couple of simple mistakes during team fights allowed the bots to raze the base of the humans.

The bot technology of OpenAI has reached a point where it can now destroy a team of highly skilled, former professional, Dota 2 players - in a match that wasn't even close.

Update: And that's game, with the AI victorious in two rounds out of three.

That being said, it should be noted that on the OpenAI's website, they admitted that the game was not your standard DotA 2 game as there had to be certain modifications made to how the game was run.

‘Holy crap!’ Video shows breaching great white shark startle researcher
A MA shark expert had a close encounter with a great white shark last week, and it was all caught on camera. The Harbormaster's Office says the White shark sighting was confirmed around 3 p.m. off Manomet Point.

In spite of the restrictions, though, OpenAI still completely dominated the first two games, through a combination of near-flawless coordination and a "play as five"-oriented playstyle". We know that this is a machine that is tasked with being incredible at Dota 2 but you really need to see just how good it is to understand why my jaw is permanently on the floor. This was an implemented as an extension of adding a win probability output to the neural network to introspect what OpenAI Five is predicting.

While the victory on Sunday was a step closer towards OpenAI's aim of beating a professional team at the world championships, their next goal-transferring skills from the closed world of a game to unpredictable real-world environments-is far more challenging.

The tournament was a best of three but clearly designed for fun more than goal. It predicted a 17 percent win chance, and indeed it lost after a healthy 35-minute battle.

This OpenAI video is meant to provide some insight into the model's planning via an output which predicts where a hero will be in the future. Last month, the company released footage of a robotic arm manipulating a cube with uncanny dexterity that was trained using reinforcement learning algorithm as the OpenAI Five. In terms of compute time the Auguest 5th model uses 190 petaflop/s-days, which is a lot of number crunching.
