- Measures
- General problem-solving ability — a blend of reasoning, knowledge, math, and coding tests, all run by the same independent team on each model's public service, so every model faces identical conditions.
- Does not measure
- Long multi-step projects, taste and judgment in writing, performance on very long documents, anything requiring the model to use tools.
- Known issues
- The recipe for blending the tests changes over time, so scores from different index versions aren't directly comparable.

Artificial Analysis is an independent measurement firm — think of them as a Consumer Reports for AI models. They run a fixed set of tests against each model's public service themselves, rather than trusting vendor claims, and combine the results into a single number. Because every model takes the same tests under the same conditions, comparing two models' index scores is meaningful in a way that comparing two vendors' press releases is not.
How to read a score: treat it as a ranking tool, not a grade. A 5-point gap means one model is clearly a tier above; a 1–2 point gap is within the noise of measurement. Check that two scores come from the same index version before comparing them — the recipe gets revised periodically.
The same firm also measures output speed, price, and performance on multi-step tasks; this site uses those measurements for the speed, cost, and agentic columns.
