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 GPT-6 Astra (max) cost $3.26 and MiniMax-M3.1-Flash $0.220, because MiniMax-M3.1-Flash used about 5.2× as many tokens for the same work, which a per-token price hides.

Each model is compared at its best-ranked reasoning-effort setting. GPT-6 Astra (max) scores 70.5 and takes 228 s to its first answer token; GPT-6 Astra (high) scores 69.6 in 36 s, GPT-6 Astra (xhigh) scores 69.0 in 122 s. MiniMax-M3.1-Flash scores 61.9 and takes 20 s to its first answer token. Higher effort means more thinking before the answer: better scores, longer waits and more tokens billed.
