Elo rating is the statistical system designed by physicist-chess player Arpad Elo in the 1960s for chess, deriving relative skill scores from pairwise match outcomes. Unexpected results swing the score more, a property that made it the natural engine behind LLM-evaluation platforms like Chatbot Arena. Scores are relative, not absolute; the gap between two players translates mathematically into win probability. It has spread far beyond chess into sports, games, and — in the last few years — AI evaluation.
