Every number keeps its provenance.
Useful benchmark coverage requires more than copying a leaderboard. We preserve the source, version, methodology, score direction and date checked.
Comparable results only
Scores are ranked only within the same benchmark version, split and evaluation configuration.
Visible caveats
Judge choice, dataset limitations and provider-reported claims are disclosed beside the results.
Permanent source links
Readers can inspect the original research instead of trusting an unexplained summary.
