Calibrated · measured on the vendor's tokenizer · 2026-06-10 Auto-counts as you type

Counts use a chars-per-token calibration measured on the vendor's own published tokenizer (mistralai/Mistral-Nemo-Instruct-2407, 2026-06-10). English prose is typically within a few percent; code and non-Latin scripts tokenize heavier. For billing-exact counts use the vendor's count-tokens API.

Frequently asked.

Practical pricing questions, separated from calculator assumptions.

Q · 01 What is Mistral Medium 3.1 priced at? +
Mistral Medium 3.1 is shown at $1.5/M input and $7.5/M output. The page stores USD per-million-token baseline pricing from mistral.ai.
Q · 02 Does this page include higher context pricing tiers? +
This page uses the public API baseline for the model row. If Mistral publishes separate long-context tiers later, the snapshot entry should be re-verified and updated.
Q · 03 Is prompt caching priced separately? +
No separate cache-read price is published for this row, so the calculator treats cached input as $1.5/M.
Q · 04 How is the effective price calculated? +
AI//COST uses the same 92/8 agentic blend everywhere. For Mistral Medium 3.1, that gives $1.98/M with only documented cache discounts included.
Q · 05 Is there a batch discount? +
Mistral pricing does not list a separate per-model batch discount in this row.
Q · 06 Are regional prices different? +
Mistral's public pricing page lets you view USD and EUR. AI//COST stores the USD baseline and handles currency variants in calculator URLs.
