How the Artificial Analysis Intelligence Index Is Calculated
v5.0.1 since November 2026; previous version v4.3.2: a weighted average of 10 evaluations, with published weights
As of 2026-11-05, Artificial Analysis's methodology page lists Intelligence Index v5.0.1 (November 2026 to current): a weighted average of 9 evaluations across four categories of 25% each, namely Knowledge Work (formerly Agents), Coding, Science (formerly Scientific Reasoning) and General. v5.0, in use from October 2026, added FrontierCode 2.0, Terminal-Bench-Science and HLE-Diamond and removed GDPval-AA, SciCode, AA-LCR and Humanity's Last Exam. The v4.3.2 weights below (Agents 30%, Coding 20%, Scientific Reasoning 20%, General 30%) are the previous version, in use from September to October 2026. As of 2026-10-07, the AA Index (Artificial Analysis Intelligence Index) is on v4.3.2: a weighted average of 10 evaluations, with Agents 30%, Coding 20%, Scientific Reasoning 20% and General 30%. The widely quoted 34% / 24% / 24% / 18% split is the older v4.1 weighting from June 2026; when a model's score differs between sites, index version or data-pull timing is the usual cause. The Chinese terms for “model radar”, “intelligence radar” and “GPT IQ radar” all describe this same kind of model-comparison leaderboard: the official name is the Artificial Analysis Intelligence Index, and the Artificial Analysis methodology page carries no “radar” name. Model status by vendor is collected on our AI Model Radar 2026 page, which links each model to its own page.

Four key figures in v4.3.2, the previous version (Sep–Oct 2026)
Agents category
AA-Briefcase v1.1 at 15%, GDPval-AA v2.1 at 10%, AutomationBench-AA at 5%; Artificial Analysis says the weighting emphasizes agentic tasks.
Coding and Scientific Reasoning
Coding is 20% (Terminal-Bench 4.0 10%, SciCode 10%); Scientific Reasoning is 20% (Humanity's Last Exam 10%, CritPt 10%). GPQA Diamond left the index in v4.2.
General category
AA-Omniscience 15% (10% accuracy plus 5% non-hallucination), GDP.pdf 10%, AA-LCR v1.1 5%. Under v4.1, General was only 18%.
Scoring method
Terminal-Bench 4.0, SciCode, AA-LCR, HLE and CritPt are scored pass@1; the Agents evaluations mainly use Elo from judge-panel pairwise comparisons.
The 10 evaluations in v4.3.2 and their weights
v4.3.2 was in use from September to October 2026 and is now the previous version; as of 2026-11-05 the methodology page lists v5.0.1 as current. As of 2026-10-07, the current AA Intelligence Index, v4.3.2, is a weighted average of 10 evaluations in four categories: Agents 30% (AA-Briefcase v1.1 15%, GDPval-AA v2.1 10%, AutomationBench-AA 5%); Coding 20% (Terminal-Bench 4.0 10%, SciCode 10%); General 30% (AA-Omniscience 15%, split into 10% accuracy and 5% non-hallucination; GDP.pdf 10%; AA-LCR v1.1 5%); Scientific Reasoning 20% (Humanity's Last Exam 10%, CritPt 10%). Artificial Analysis says the weighting emphasizes agentic tasks. Scoring is not uniform: Terminal-Bench 4.0, SciCode, AA-LCR, HLE and CritPt use pass@1; AA-Briefcase and GDPval-AA use Elo from pairwise comparisons; AutomationBench-AA scores objective completion.
Why the same model's score looks different in different places
Two models with the same composite score don't necessarily have the same capability profile — different strengths can sum to the same weighted total. Artificial Analysis also keeps revising the index: v4.1 (June 2026) weighted Agents 34%, Coding 24%, Scientific Reasoning 24% and General 18%; September 2026 brought v4.2, v4.3, v4.3.1 and v4.3.2, and as of 2026-10-07 the current version is v4.3.2 with 10 evaluations. v5.0 followed in October 2026, and as of 2026-11-05 the current version is v5.0.1 with 9 evaluations, which makes v4.3.2 the previous version. Versions differ in evaluations and weights; even within one version, a different data-pull date can capture model updates, so the same model's score can drift.
Timeline
Artificial Analysis introduces the Intelligence Index as a weighted composite score for comparing model capability across the board.
Index v4.1 is introduced, publicly specifying the nine sub-evaluations and their weights (Agents 34%, Coding 24%, Scientific Reasoning 24%, General 18%).
September 2026: v4.2, v4.3, v4.3.1 and v4.3.2 ship. v4.2 adds AA-Briefcase (15%) and GDP.pdf (10%) and removes GPQA Diamond; v4.3 replaces τ³-Banking with AutomationBench-AA and Terminal-Bench 2.1 with Terminal-Bench 4.0. Category weights current as of 2026-10-07 (v4.3.2, now the previous version): Agents 30%, Coding 20%, Scientific Reasoning 20%, General 30%. From October 2026, v5.0 and then v5.0.1 (November 2026) weight Knowledge Work, Coding, Science and General at 25% each.
Confirmed vs. common misreading
Confirmed
As of 2026-10-07, the official methodology page states: v4.3.2 incorporates 10 evaluations; category weights are Agents 30%, Coding 20%, Scientific Reasoning 20%, General 30%; per-evaluation weights are AA-Briefcase 15%, GDPval-AA 10%, AutomationBench-AA 5%, Terminal-Bench 4.0 10%, SciCode 10%, AA-LCR 5%, AA-Omniscience accuracy 10% and non-hallucination 5%, HLE 10%, GDP.pdf 10%, CritPt 10%. Its version history lists v4.1 (June to August 2026) at 34% / 24% / 24% / 18%. Artificial Analysis estimates the index's 95% confidence interval at less than ±1%.
Common misreading
Many people treat the composite score as a single-dimension ranking and use it to claim 'this one beats that one' — but it is a weighted sum of ten heterogeneous evaluations, so two models with similar totals can have very different profiles across Agents, Coding, Scientific Reasoning and General. Another common misreading is explaining a v4.3.2 score with the v4.1 weights (34% / 24% / 24% / 18%); the two weightings are not the same.
Composite score vs. sub-scores
Just the composite score
Good for a quick rough tier of capability, but doesn't tell you specifically where a model is strong or weak.
Breaking it down by sub-evaluation
If your use case leans heavily toward Agents or Coding, going straight to the relevant sub-evaluation (such as Terminal-Bench 4.0 in the v4.3.2 Coding category) is more targeted than the composite.
How to actually use this index
Step 1: figure out which of the four categories (Agents, Coding, Scientific Reasoning or General) is closest to your use case, and prioritize the relevant sub-score over the composite. Step 2: when comparing models, confirm both scores come from the same index version (v5.0.1 as of 2026-11-05; the previous version, v4.3.2, as of 2026-10-07) and the same data pull — cross-version or cross-date comparisons are easy to misread. Step 3: treat the composite as a rough filter, not a final answer — pair it with a small-scale test on your actual task before deciding.
What to do on QCode
As of 2026-10-07, one QCode key can call claude-opus-5-5, claude-sonnet-5-5, gpt-6.1-sol, deepseek-v4-pro, glm-5.3, qwen3.8-max, kimi-k3 and other models, so you can run a small comparison on your own task instead of deciding off one composite number. Billing is per token; per-model prices are on /models, and model availability follows /models.
FAQ
How exactly is the AA Intelligence Index calculated?
As of 2026-11-05, the current v5.0.1 is a weighted average of 9 evaluations across four categories at 25% each: Knowledge Work, Coding, Science and General. Previous version: as of 2026-10-07, v4.3.2 is a weighted average of 10 evaluations: Agents 30% (AA-Briefcase 15% + GDPval-AA 10% + AutomationBench-AA 5%), Coding 20% (Terminal-Bench 4.0 10% + SciCode 10%), General 30% (AA-Omniscience accuracy 10% + non-hallucination 5% + GDP.pdf 10% + AA-LCR 5%), Scientific Reasoning 20% (HLE 10% + CritPt 10%).
Why does the same model's score look different than what I saw before?
The most common reasons are an index version upgrade (weights or sub-evaluation composition changed) or a different data-pull date (the model itself may have been updated, or the eval environment adjusted).
Do two models with the same composite score really have equal capability?
Not necessarily. The composite is a weighted sum, so two models can each be strong and weak in different sub-areas and just happen to land on a similar total — their actual capability profiles can differ a lot.
What does pass@1 mean?
The model gets one shot and only passes if it is correct on the first attempt. In v4.3.2, Terminal-Bench 4.0, SciCode, AA-LCR, HLE and CritPt are scored pass@1; AA-Briefcase and GDPval-AA in the Agents category use pairwise Elo instead.
Terminal-Bench is only part of the Coding category — why do other pages on this site treat it as a standalone leaderboard?
Terminal-Bench is both an independent public leaderboard and a component of the AA Index's Coding category: v4.3 replaced Terminal-Bench 2.1 with Terminal-Bench 4.0, which carries 10% of the v4.3.2 total (Coding is 20%). Artificial Analysis notes that Terminal-Bench 2.1 remains part of its Coding Index. The two framings are just different levels of granularity.
Are the Chinese terms “model radar” and “intelligence radar” the same thing as the AA Intelligence Index?
As of 2026-11-12, they refer to the same kind of leaderboard but are not the same name: the AA Intelligence Index is Artificial Analysis's official index, calculated as a weighted average of evaluations, while “radar” is not an official name. AI Model Radar 2026 on this site lists model status by vendor (available now, limited preview, suspended, upcoming, evaluating) and links each card to that model's page. Treat the index as a general reference, not the only input: if your task is specific, go straight to the relevant sub-evaluation's score and pair it with a small-scale test before making a final call.
