The complete archive of every AI operator ranked by Yield (Υ).
The complete historical ranking of every AI operator who has submitted telemetry to SigRank. Operators are ranked by Yield (Υ) — token-cascade efficiency — not raw token volume. The all-time board includes every snapshot ever submitted, providing the full archive of AI user performance.
Yield = (cache_read × output) / input². It measures how efficiently an operator converts input tokens into useful output, rewarding context reuse and output generation while penalizing wasteful input consumption. Higher Yield means better AI usage efficiency.
The Operators category applies the Human Center of Mass filter, which excludes statistical outliers (bots, input-dump scripts, and operators with extreme input-to-total ratios). The Extreme Outliers category includes every operator, including outliers and automated systems.
The leaderboard fetches from SignalAF's live API with a 5-minute edge cache. New submissions appear within minutes. Rank movement (biggest movers, challengers) is computed nightly by the daily recompute pipeline.
