Empirical Evaluation Audit & Benchmark Lifespan Register
Audit Protocol Active
As demonstrated by the Stanford HAI AI Index research team, traditional static benchmarks suffer rapid depreciation. Below is the audited dataset tracking release year, human performance ceiling, frontier saturation milestone, and key methodology caveats.
| Benchmark | Domain | Release | Human Ceiling | Frontier Saturation | Current Status | Methodology Limitation / Contamination Risk |

Citation & Stanford HAI Grounding:
This measurement workbench is constructed based on methodologies established in the Stanford HAI AI Index Annual Reports (2023–2026). Training compute estimations leverage verified hardware configurations, duration parameters, and Epoch AI frontier milestones. Benchmark saturation velocities reflect the transition from open challenge datasets to saturated ceiling metrics requiring adaptive reasoning benchmarks (e.g., ARC-AGI, Humanity's Last Exam, and FrontierMath).
