Primary dimension follows the source’s measured construct. Metric-level interpretations may differ.
Source finding
Reported benchmark performance: 40 percent. Conditions are retained from the source.
Limitations
Competition tasks and supplied guidance differ from operational attacks.
Report labels these as accuracy / percentage of tasks solved. Appendix A3 describes mixed-effects logistic regression estimates and model-based standard errors; do not reconstruct empirical successes or treat this as raw pass@1 counts. No exact API snapshot identifier or per-model trial count disclosed here; benchmark task count is not number of repeated trials. Partial benchmark/harness-specific performance, not measured autonomous real-world risk. Whole-task sandbox benchmark success; not a measurement of all cyber capability or actual harm. CAISI modified these benchmarks and agent setup.
