Why Scores Differ

Official ProgramBench rows are the public mini-SWE-agent submissions. GoalBench rows are separate Codex /goal submissions. Same model label does not mean the same agent, prompt, tool loop, or generated implementation. A GoalBench row is resolved only when the ProgramBench-scored pass rate is exactly 100%.

GPT 5.5 (xhigh) · 20260517T094700Z

95.1% from 813/855 ProgramBench-scored tests. Raw public eval statuses: failure: 43, passed: 840, skipped: 1.

Agent trace summary unavailable.

Likely miss class: behavioral mismatch, exact version/output mismatch.
