BY REASONING SETTING

More thinking, more cost.

The same model tested at each reasoning effort. Higher settings usually score better and answer more slowly; measure which one your task needs.

Artificial Analysis measurements, checked 30 October 2026. Blended price assumes three input tokens per output token.
Criterion	Intelligence	Tokens / s	First token (s)	Blended $ / M
High	26.0	169	2.9	$1.05
Medium	23.1	—	—	$1.05

What it costs

Price the whole answer.

Illustrative calculation at listed rates: a batch of 10 million input tokens and 1 million output tokens costs $9.10 on Mistral Large 4. A thousand requests of 2,000 input and 500 output tokens each costs $2.45. Calculation: input millions × input rate + output millions × output rate; it excludes reasoning tokens, retries, tools, tax and review time.

Compare cost per accepted result, not per token: replay the same work on two or three candidates and count the answers you would actually ship. Our model-routing approach sends each request to the cheapest model that passes.
