Limits RegistryPUBLIC RECORD
Limits RegistryDeepMind reported in an October 2019 Nature paper that AlphaStar achieved Grandmaster status — the highest league on the official StarCraft II ladder — playing under conditions designed to match human constraints (a limited camera view of the game rather than full map access, and an action-per-minute rate capped to be comparable to skilled human players). StarCraft II presented harder challenges than earlier game AI milestones because of its long time horizons, imperfect information, and enormous action space.

DeepMind's AlphaStar reached Grandmaster level on the official Battle.net ladder for StarCraft II, ranking above 99.8% of officially ranked human players, using all three playable races and without any restrictions on its camera view or action rate beyond human-comparable limits.

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.
