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 Pro 0424 (max) cost $0.122 and GPT-6.1 Sol (max) $0.724, because DeepSeek V4 Pro 0424 (max) used about 1.2× as many tokens for the same work.

Each model is compared at its best-ranked reasoning-effort setting. DeepSeek V4 Pro 0424 (max) scores 59.7 and takes 49 s to its first answer token; DeepSeek V4 Pro 0424 (high) scores 57.9 in 25 s, DeepSeek V4 Pro 0424 (no reasoning) scores 50.8 in 2 s. GPT-6.1 Sol (max) scores 69.9 and takes 275 s to its first answer token; GPT-6.1 Sol (high) scores 67.7 in 29 s, GPT-6.1 Sol (xhigh) scores 67.7 in 84 s. Higher effort means more thinking before the answer: better scores, longer waits and more tokens billed. How reasoning effort changes scores and cost.
