Claude Opus 5.5 leads Remote Labor Index at 21.25. The full leaderboard above lists every recorded measurement, not just the headline number.
15 models have recorded scores on Remote Labor Index, spanning a score spread of 20.42.
tensor.news grades Remote Labor Index B for integrity (score 72/100), ranking #51 of 65 benchmarks we assess across discrimination, saturation, contamination resistance, harness comparability, and freshness.
No — Remote Labor Index still has headroom and continues to discriminate between models rather than bunching them at the ceiling.
Its test set is unknown, so contamination risk is on the table: a high score may partly reflect training-data overlap rather than capability.
Scores are reported under a consistent harness, so comparisons on Remote Labor Index are reasonably apples-to-apples.
Every Remote Labor Index measurement is source-backed and tagged reproduced, self-reported, or unverified; the underlying record cites epoch.ai/data/eci_benchmarks.csv.
