Artificial Analysis Intelligence Index
General intelligence: knowledge, reasoning, math and coding rolled into one number
What it measures
Artificial Analysis is an independent evaluator. It runs a dozen public evaluations itself under one harness (knowledge Q&A, scientific reasoning, competition math, coding, terminal tasks) and blends the results into a single 0–100 index.
Higher means stronger overall. It answers “roughly where does this model sit?”
quickly, but it cannot tell you about any single skill. Each reasoning-effort setting (low / high / max) of a model is scored as its own entry.
Reading the scores
a relative 0–100 index, only meaningful among models scored in the same period; its composition shifts as evaluations are updated.
