|---|---|
| Research status | Research date October 4, 2026. 2 source URLs checked. This documents the inspected sources, not an exhaustive inventory of every publication. |
| Not published | quality-benchmark Original wording The 95.0% Advanced Cybersecurity Completion Rate measures answered or completed requests, not answer quality, pass@1, or exploit success. It is excluded from benchmark data. |
| Not published | cyber-task-success-benchmark Note OpenAI says a later system card will provide further evaluations; the accessible release does not report internal sample counts. |
| Not published | cyber-task-success-benchmark Note No new exact cyber-task-success score or evaluation sample protocol is published in the checked current API page or release. The existing 95% completion-rate row is not task success. |
