Report identity & conditions

Data as of2026-10-14· Report published—. See individual records for run dates and test conditions.

  • The benchmark has 225 exercises across C++, Go, Java, JavaScript, Python and Rust. Some runs report 223 or 224 test cases; the actual count is retained for each run.
  • The observation date is when we retrieved the data. Run dates, samples, reasoning settings, edit formats, tool versions and commits are recorded separately. This leaderboard includes historical runs and is not a current overall model ranking.
  • Display names and CLI aliases do not establish an exact snapshot, so they are not automatically linked to catalog versions. Dollar costs for a run are not reusable API unit prices, and runs with different settings are not controlled comparisons.
