Artificial Analysis Intelligence Index
A composite intelligence score (AAII v4.0) that aggregates a model's performance across 10 challenging evaluations spanning reasoning, knowledge, coding, agentic tasks, and instruction-following (GDPval-AA, τ²-Bench Telecom, Terminal-Bench Hard, SciCode, AA-LCR, AA-Omniscience, IFBench, Humanity's Last Exam, GPQA Diamond, and CritPt) into a single ~0–100 index.
What this benchmark measures
A composite intelligence score (AAII v4.0) that aggregates a model's performance across 10 challenging evaluations spanning reasoning, knowledge, coding, agentic tasks, and instruction-following (GDPval-AA, τ²-Bench Telecom, Terminal-Bench Hard, SciCode, AA-LCR, AA-Omniscience, IFBench, Humanity's Last Exam, GPQA Diamond, and CritPt) into a single ~0–100 index.
Rows on this page are sourced from public benchmark artifacts, leaderboard exports, or source-linked model reports. Each row keeps benchmark version, source model name, and available run details attached to the score.
The metric shown here is Index. It should be interpreted within Artificial Analysis Intelligence Index, not compared as part of a site-wide ranking.
Frequently asked
What is Artificial Analysis Intelligence Index?
A composite intelligence score (AAII v4.0) that aggregates a model's performance across 10 challenging evaluations spanning reasoning, knowledge, coding, agentic tasks, and instruction-following (GDPval-AA, τ²-Bench Telecom, Terminal-Bench Hard, SciCode, AA-LCR, AA-Omniscience, IFBench, Humanity's Last Exam, GPQA Diamond, and CritPt) into a single ~0–100 index. It is a reasoning benchmark measured by Index.
What does Index mean on Artificial Analysis Intelligence Index?
Artificial Analysis Intelligence Index reports Index; higher is better. Scores are shown only within Artificial Analysis Intelligence Index and are never averaged with other benchmarks.
What is the top reported Artificial Analysis Intelligence Index score?
Claude Fable 5 has the top reported score on Artificial Analysis Intelligence Index: 65 (Index).
Why do Artificial Analysis Intelligence Index scores differ across runs?
Harness, scaffold, reasoning effort, and prompt setup change results, so two runs of the same model can differ. evals.report keeps each score with its run context so the differences stay visible.
Does evals.report rank models across benchmarks?
No. Artificial Analysis Intelligence Index scores are shown within their own metric; evals.report never combines benchmarks into a composite ranking or a single "best model".
