Measurement of intelligence

Version 0.1 · 13 September 2026

If the maps in 01 are theories, this file is the instrument panel. Intelligence Radar refuses to rank models from a single number, but it also refuses to treat every eval as equally informative.

Human measurement (background)

  • Psychometric batteries — WAIS-class tests, Raven matrices, specialized factor batteries. Human g research lives here.
  • Expert work samples — the closest human analogue to GDPval / OSWorld: can a person produce the artifact a job requires.
  • Animal batteries — delayed match, tool use, social inference. Relevant when someone claims “animal-level AGI.”

These are monitored for conceptual transfer, not for daily model ranking.

Artificial measurement — what still discriminates in September 2026

Classic exams (MMLU, GSM8K, HumanEval, HellaSwag, ARC-Challenge) are largely saturated at the frontier. They remain useful as regression tests and as historical series, not as rankers.

Instruments that still move, with caveats:

Instrument Layer it hits Caveat
Humanity’s Last Exam (HLE) expert knowledge + reasoning tool-use variants change the number
FrontierMath / FrontierMath Erdős deep mathematical research tiny N; one problem moves the headline
GPQA Diamond graduate science QA approaching saturation at the very top
SciCode scientific coding scaffold-sensitive
SWE-bench Verified / Pro, DeepSWE, Frontier Code software engineering agents harness and test-contamination risk
Terminal-Bench 4.0 CLI / sysadmin / research agents version jumps rewrite history
OSWorld 2.0 long-horizon computer use live desktop; expensive to run
ARC-AGI-3 abstract interactive reasoning wrapper/harness can swing scores by tens of points
GDPval-AA v2, GDP.pdf, AA-Briefcase professional knowledge work closer to economic value
AutomationBench-AA agentic office workflows private set; good contamination resistance
AA-Omniscience, SimpleQA, CritPt factuality / calibration “smart but wrong” detector
Artificial Analysis Intelligence Index v4.3 composite of the above class re-bases; never compare raw scores across index versions
Epoch Capabilities Index (ECI) long-run capability scale best for history, not shopping
LMSYS / Arena-style preference human taste not a substitute for task success

Rules for using scores

  1. Same harness, same date, same effort setting. “Max” vs “medium” reasoning is a different product.
  2. Price per completed task beats price per million tokens when the model burns hidden reasoning tokens.
  3. Availability is part of the score. A preview-only or capacity-gated model is tagged, not treated as generally usable.
  4. Open weights vs API are different goods (latency, privacy, sovereignty, fine-tune rights).
  5. A 10% degradation in Task Router language means: on the task-weighted blend of the five mapped benchmarks, comparative task-fit proxy is within 10% relative of the Frontier model (see task-router/METHOD.md). It is not “10 Elo” and it is not “10 index points.”

What we do not pretend to measure well

  • Scientific novelty (a model can ace HLE and still not find a new theorem).
  • Taste, aesthetics, and institutional judgment.
  • Long-run reliability in production (weeks of agent autonomy).
  • Alignment, refusal quality, and dual-use except via lab preparedness designations and independent red-team reports.
  • Consciousness.
