In one line

xAI's August flagship and its strongest entry on the AA index at launch: 70.8% on CursorBench 3.2, 87.0% on VulcanBench v3, and selectable reasoning effort from low to xhigh. Two honest caveats: the 500K context is half what the Claude, GPT and Kimi flagships offer, and measured throughput (~58 tok/s) sits below the field median.

Artificial Analysis Intelligence Index, official scale (the number published on artificialanalysis.ai), relayed by OpenRouter and refreshed automatically: last read October 14, 2026. 209 models carry a current official measurement. A value marked ~ is converted from an earlier snapshot because no current measurement is published; an unmeasured model is never ranked. Context, price, modality and listing dates come from the public OpenRouter model list (refreshed automatically on the live site; static copy retrieved October 3, 2026) and vendor pages. Missing values are not published or not yet verified - shown as -. Sources are linked inside the app (the Ranking chapter and About > Methodology).
