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. Cost, tokens and time per benchmark task are measured: Artificial Analysis’ averages over its whole Intelligence Index run.

Per token is not per task: an average task of Artificial Analysis' Intelligence Index cost $1.87 on Gemini 4 Hydrogen (high) and $2.47 on GPT-6 Sol (max), and Gemini 4 Hydrogen (high) wrote 1.6× as many output tokens for the same work, which a per-token price hides.

Each model is compared at its best-ranked reasoning-effort setting. Gemini 4 Hydrogen (high) scores 63.4 and takes 16 s to its first answer token. GPT-6 Sol (max) scores 62.7 and takes 67 s to its first answer token; GPT-6 Sol (xhigh) scores 58.4 in 25 s, GPT-6 Sol (high) scores 58.1 in 11 s. Higher effort means more thinking before the answer: better scores, longer waits and more tokens billed. How reasoning effort changes scores and cost.
