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) · 20260518T232006Z

67.2% from 396/589 ProgramBench-scored tests. Raw public eval statuses: error: 4, failure: 204, passed: 519, skipped: 35.

Agent trace: 59 shell command(s), 37 executable-observation command(s), 9 build command(s), 2 blocked attempt(s). Raw Codex logs are not published.

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