OpenAI has created a Dota 2 bot that can beat top professionals at 1v1 matches under standard tournament rules. The bot learned the game from scratch through self-play, without using imitation learning or tree search. This achievement is seen as a step towards developing AI systems that can accomplish specific goals in complex situations involving humans. --- Why it matters: This matters to researchers and engineers because it demonstrates the potential of self-supervised learning in achieving high-level performance in competitive games. The success of this bot could pave the way for more sophisticated AI systems that can tackle real-world challenges. Source: https://openai.com/index/dota-2
