A leaderboard that shows its receipts.

Ranked by total observed accounted tokens over the trailing 30 UTC days, across Codex, Claude Code and Devin. Coverage, freshness, and consent sit beside every result.

No rankings before the evidence layer

AI Charts will not turn a local counter into a public claim. When public reads are enabled, entries carry their measurement scope, source coverage, account consent, and correction history.

Inspect the measurement contract

Comparable does not mean universal.

Different providers expose different evidence. The leaderboard keeps provider, model, subscription, and coverage dimensions distinct instead of collapsing them into one score.
