OpenAI's team of AI-powered Dota 2 bots have reached yet another impressive milestone - it was able to beat the five veteran players in a 3-on-3 match, dominating two rounds before being defeated narrowly in the third match. "Despite that, OpenAI five thrashed some of the most popular ex Dota 2 players, including Ben "Merlini" Wu, William "Blitz" Lee, Ioannis "Fogged" Lucas, the current pro player David "MoonMeander" Tan and play-by-play commentator Austin" Capitalist" Walsh.

OpenAI's 1v1 bot beat pro player Danil "Dendi" Ishutin at last year's The International, and the institute says the learning process for OpenAI Five is much more complex, requiring 256 GPUs and 128,000 CPU cores.

Next, OpenAI's developers plan to take the bots to Valve's official global tournament, where they'll compete against the best Dota 2 players in the world. There, OpenAI bots will face the winning team, for its biggest challenge yet. Even though the artificial intelligence bested the professional Dota 2 players two-out-of-three, the humans managed to score a victory in the third match. The characters Open AI played were selected by Twitch users, giving Team Human a slight advantage. In the second game, however, humans showed a spark and conquered a tower but lost eventually.

The English transfer window closes on Thursday and United would struggle to find a replacement for Pogba before the deadline. He goes on to report that United do not want to sell the "important" player as they see him as the franchise of the club.

A few years ago, many researchers thought it was impossible for AI systems to get so good at complex team-based games like Dota 2, but here we are.

Sunday's tournament was a test run before the world Dota 2 championships later this month, where the bots will compete against a team of professional players. OpenAI had the capacity to predict its chance of winning during each stage of the game, as well as during character selection.

Following the victory, Musk tweeted congratulating the OpenAI team. OpenAI co-founder and CTO Greg Brockman has previously described it as - if you assume that it takes a human at least 12,000 hours to become a professional at the game, OpenAI's systems essentially play 100 human lifetimes of experience every day to train. Well, the AI platform developed by OpenAI would like to have a word, humans.
