Elon Musk's OpenAI bot beat a human at video games last year. Now it will take on five at once.

OpenAI made headlines last year when it proved a bot could beat a professional gamer head to head at one of the world's most complex video games. But it had one more gaming goal to conquer -- to beat a professional team of five. Now, after proving the bot can beat teams that rank in the top 1 percent of amateur players for its game of choice, OpenAI will get its chance to shine at the International, one of the world's most established video game tournaments. The tournament is where the researchers hope to showcase how far Elon Musk-backed OpenAI has come in terms of its ability to control its five-character team as well as any team of five humans can. While machines have beaten humans at games -- from IBM computer Deep Blue's chess victory in 1997 to a Google bot's win over Go champion Lee Sedol in 2016 -- each game has offered a new challenge for artificial intelligence to solve.
