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-5.6 Sol (max) cost $1.99 and MiniMax-M3.1-Flash $0.220, because MiniMax-M3.1-Flash used about 3.4× 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-5.6 Sol (max) scores 68.1 and takes 87 s to its first answer token; GPT-5.6 Sol (xhigh) scores 66.6 in 36 s, GPT-5.6 Sol (high) scores 66.3 in 9 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.
