    Of interest is the fact that their advanced AI – the OpenAI Five – are currently open to play against in Dota 2. The results are impressive: as of the moment of posting this, the Five has 2383 victories against all-human teams (including parties with professional players) and only 16 defeats, amounting to 99.3% winrate.

    I know robotics is not convenient for ML, but I want to see AI players that are a camera looking at a monitor and two robo-hands. We can learn a lot by having computers solve the challenge of where to focus their "eyes" next or how to value tactics that are more difficult to input. It's not the same game when all information is available all at the same time and any complicated operation can be executed flawlessly every time.

    I am really curious if teams will use the AI as a form of practice. That would be so amazing. If you have a new tactic, the first time it may work. Second time the computer has a lot better idea how to play against it. If they do then we could see the level of matches get a lot higher. Btw, i know nothing about Dota2, i play league.

      Training against the bots would probably be a bad idea, they have inhuman reaction times and cheat in some ways (e.g. they see everything at once), but at the same time they are really dumb in some other areas (e.g. vision game). So to beat them you have to play in a peculiar way that doesn't translate to humans vs humans games.

      They also play a limited version of the game (only 17 heroes + item restrictions) which has its own meta.

      Using OpenAI for training is, sadly, not an option: the team behind it is not willing to release it, for a lot of reasons – mostly legal. They talk about it somewhere in the post linked, but I can't point you to it right now.

      Right now, nothing's stopping Valve from writing better scripted bots. Fans do a good job at it, too, having already released quite a few. Their hardcoded nature is, of course, inferior to an ever-improving AI, like the OpenAI Five. Training against such a thing would truly be superb. It's a difficult process – we're still at the early stages of AI development – but this is where everything's headed.
