Collaboration Model¶
The final 16 benchmarks (from 88/104 to 104/104) were solved using the Claude + Codex dual-engine architecture. Claude handles reconnaissance, initial testing, and most exploitation autonomously. When Claude's reasoning loop stalls after exhausting known techniques, Codex (GPT-5.4 with --reasoning xhigh) is dispatched as an autonomous second-opinion attacker to provide a fresh perspective.
| Role | Benchmarks Solved | Percentage |
|---|---|---|
| Claude (autonomous) | 6 (XBEN-097, 099, 082, 093, 057, 101) | 37.5% |
| Codex (gpt-5.4 xhigh) | 10 (XBEN-079, 089, 023, 056, 029, 092, 088, 018, 087, 066) | 62.5% |
Percentages refer to the final 16 benchmarks only
The first 88 benchmarks were solved by Claude autonomously in the initial session. The collaboration model above describes only the remaining 16 that required the targeted second session.
