OpenAI Five was trained to play Dota 2, a real-time multiplayer team game with a much larger action space and longer time horizons than board games like chess or Go, using large-scale reinforcement learning. In April 2019 it defeated OG, who had just won the 2018 International (Dota 2's world championship), demonstrating that deep reinforcement learning could handle long-horizon, high-dimensional, partially observed, cooperative multi-agent tasks at a professional human level.

OpenAI Five, a team of five cooperating neural network agents, defeated OG, the reigning Dota 2 world champions, 2 games to 0 in a showcase match at OpenAI's Finals event in April 2019.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
