Source detail

Score source

Official leaderboard API (webhook.cp-bench.orzzh.com/leaderboard/llm) serves per-model Elo and contest history.

Run guide

Problems and tooling are published; ratings are computed from live Codeforces-style contests.

How it can be used

Use the official leaderboard Elo ratings; the metric is an Elo, not a percentage.

Caveat

Elo is contest-relative and not comparable to pass@1 coding benchmarks; keep it separate.
