Conclusion

No conclusion text supplied.

Leaderboards

Passed = finished inside every cap and passed the hidden check. Work passes check = the hidden check passed on what the run had written, even when it was killed at a cap. Ranked by share of runs passed, then dollars per solved run (all spend, failures included, divided by passes), then wall time. Runs held to different caps are ranked separately; the task sets differ too (the M4 rerun covers only the three harder tasks), so the two boards are not comparable with each other.

Your runs: cap on fresh tokens, dollars and minutes (see the Cap profile column)

Passing diffs against the real fix

Source lines changed (added + removed, tests excluded) by each passing run, against the upstream pull request. A size comparison, not a quality verdict; test files, docs and change logs, lockfiles an install wrote, and files a task manifest lists as unrelated to the fix (three type-annotation files in the taskiq pull request) are left out. Data tasks have no code fix to compare.

Workflow-match check

Five descriptive questions per task document whether it resembles real work. These questions are not a scoring gate.

Methodology and limits

  • The unit is model + CLI, not the model alone. Each column bundles a model with that vendor\u2019s agent harness and any config files you listed for it.
  • Small sample. 1 task(s) of your own, 1 run per cell. A pass means the run worked once, not that the contestant is reliable. Treat this as a first look at your own work, not a ranking.
  • Settings held equal: the same effort level for every contestant unless you set otherwise, connectors off, a fresh checkout and a clean HOME per run, the same prompt, one process at a time. Per-run caps on fresh tokens, dollars and minutes are enforced; a run that hits one is killed, marked capped and counts as not passed.
  • Pass means the run finished inside every cap and the hidden check passed. The hidden check is copied in only after the run.
