WorkflowArena - SCI - Resolved: leaderboard
WorkflowArena v1, 145 tasks across eight domains, native Resolved on SCI. Resolved requires all acceptance criteria; continuous outcome credits partial progress. Overall is the equal-weight domain mean. Codex 0.164.0 / Claude Code 2.1.280, exact native harness and effort retained. No transfer from the separate 32-task workflow-transfer cohort, no cross-harness or compute pooling.
Metric: Resolution Rate (%). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 25 models tracked.
