Artificial Analysis Intelligence Index

A single composite score for a model's general capability, aggregating a basket of reasoning, knowledge, coding, agentic and long-context evaluations run independently by Artificial Analysis rather than reported by the model's vendor.

Methodology

Artificial Analysis runs each component evaluation itself through the model's public API and combines the results into one weighted index. Version 4.2, published on 4 September 2026, gives privately held-out test sets 40 per cent of the total weighting — double the share in v4.1 — through AA-Briefcase, AA-Omniscience and the solutions to CritPt, and adds GDP.pdf, a long-context document-reasoning set built by Surge AI. GPQA Diamond was removed as saturated.

Important limitations

A composite index hides which component moved: two models with the same score can be strong in very different places. The public portion of the basket remains vulnerable to training contamination, which is the reason the maintainer keeps increasing the held-out share. Weightings and component sets change between versions, so scores are not comparable across index versions.
