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 DeepSeek V4.1 Flash 1017 (max) cost $0.262 and MiMo-V2.6-Pro $0.133, because DeepSeek V4.1 Flash 1017 (max) used about 2.1× as many tokens for the same work, which a per-token price hides.

Each model is compared at its best-ranked reasoning-effort setting. DeepSeek V4.1 Flash 1017 (max) scores 64.0 and takes 11 s to its first answer token. MiMo-V2.6-Pro scores 64.0 and takes 39 s to its first answer token. Higher effort means more thinking before the answer: better scores, longer waits and more tokens billed.
