OpenAI Five Defeats 99.95th Percentile Dota 2 Players in Live Benchmark Match

OpenAI Five won a best-of-three series against a team of five high-ranked Dota 2 players, four of whom are professional players, in a live event watched by approximately 100,000 concurrent viewers. The match was framed as a benchmark result demonstrating the system's capability against near-top-tier human competition. This represents a milestone in the ongoing development of OpenAI's reinforcement learning-based Dota 2 agent.
