OpenAI Five shows early-game strength but loses two matches to top Dota 2 players at The International 2018

AI Impact Summary

OpenAI Five delivered competitive opening play in The International 2018, staying in contention for 20–35 minutes before losing two games to top Dota 2 players. This shows strong early- and mid-game planning in a highly strategic, real-time environment while revealing gaps in late-game adaptation to human strategies. For teams building live-game AI opponents, this implies a need for longer-horizon training and improved opponent modeling to close late-game gaps.
