# AI Benchmarking
**Domain:** Artificial Intelligence / Evaluation / Research Governance
**Doc Type:** Canonical Concept Node
**Maturity:** Developed
## Definition
**AI benchmarking** evaluates systems on shared tasks, datasets, metrics and protocols so that performance can be compared under specified conditions.
## Historical Context
The dispute surrounding [[wiki/Speech Understanding Research|Speech Understanding Research]] and [[wiki/HARPY|HARPY]] helped motivate a DARPA evaluation regime in which methods and benchmark tasks were prescribed in advance and systems were tested annually.
## Governance Context
Benchmarks make comparison possible, but they also decide what counts as performance. A system can optimize the test while leaving important capabilities, populations or deployment conditions outside the measured frame.
## Psychometric and introspective evaluation
[[thoughts/The Luxembourg Preprint|The Luxembourg Preprint]] shows why the prompt frame must be treated as part of the benchmark. A structured inventory and an open-ended therapeutic dialogue can appear to measure the same psychological construct while producing sharply different model behavior.
[[wiki/Prompt-Sensitive Behavioral Stability|Prompt-Sensitive Behavioral Stability]] names the comparative target across those frames. [[wiki/Psychometric Deformation|Psychometric Deformation]] names the failure mode in which test-induced output is mistaken for a persistent personality or mental state. A valid benchmark should preserve prompts, order, model version, sampling settings, complete interaction history, repeated trials, and the boundary between observed response and inferred interiority.
## Key Insight
**A benchmark does not merely measure success; it operationally defines the success that institutions can recognize.**
