Each publisher runs its own tasks, harnesses and effort settings, so their overall verdicts can differ; BenchLeader reconciles them on one scale. † measured at another effort setting of the same model (the publisher did not test the one compared here).

Price, speed and latency

List prices blended at three input tokens per output token. Per-task prices use the token counts on the methodology page; suite cost is what Artificial Analysis paid to run its whole Intelligence Index.

Per token is not per task: on Artificial Analysis' full suite Grok 4.7 (high) cost $2.73 and Kimi K3.1 Pro $2.11, because Grok 4.7 (high) used about 1.7× as many tokens for the same work, which a per-token price hides.

Each model is compared at its best-ranked reasoning-effort setting. Grok 4.7 (high) scores 63.9 and takes 20 s to its first answer token; Grok 4.7 (xhigh) scores 61.6 in 35 s, Grok 4.7 (low) scores 61.0 in 4 s. Kimi K3.1 Pro scores 66.8 and takes 28 s to its first answer token. Higher effort means more thinking before the answer: better scores, longer waits and more tokens billed.
