If you've ever tried to learn Dota 2 from scratch, you'll be able to appreciate how many different elements and decisions there are to juggle at any given moment. That's partially why it's so much fun watching the progress of OpenAI Five, a variant of the AI that beat pro players in 1v1 games at last year's International. The makers of the bot have announced that it's now beating regular teams of humans with abandon, including a 5500 MMR-rated group of humans and a flawless victory against a group of Valve employees.
