| BenchLeader Index | 59.7 | 70.5 | GPT-6 Astra |
| AA Intelligence Index v4.3.2 | 30.4 | 52.7 | GPT-6 Astra |
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 Pro 0424 (max) cost $0.122 and GPT-6 Astra (max) $3.26, because DeepSeek V4 Pro 0424 (max) used about 1.4× as many tokens for the same work, which a per-token price hides.
Each model is compared at its best-ranked reasoning-effort setting. 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 Astra (max) scores 70.5 and takes 287 s to its first answer token; GPT-6 Astra (high) scores 69.7 in 44 s, GPT-6 Astra (xhigh) scores 69.0 in 144 s. Higher effort means more thinking before the answer: better scores, longer waits and more tokens billed. How reasoning effort changes scores and cost.
