• "Pluribus is the first AI bot capable of beating human experts in six-player no-limit Hold’em, the most widely played poker format in the world. This is the first time an AI bot has beaten top human players in a complex game with more than two players or two teams.

• We tested Pluribus against professional poker players, including two winners of the World Series of Poker Main Event. Pluribus won decisively.

• Pluribus succeeds because it can very efficiently handle the challenges of a game with both hidden information and more than two players. It uses self-play to teach itself how to win, with no examples or guidance on strategy. 

• Pluribus uses far fewer computing resources than the bots that have defeated humans in other games. 

• The bot’s success will advance AI research, because many important AI challenges involve many players and hidden information."
