cached input $0.15 per 1M, printed per model on docs.mistral.ai/inference/pricing — the third Mistral pricing page, added to this row's sources on 2026-09-03. It is the −90% discount the other two pages describe only in prose

window stated on the model's own page; max output not stated

cached input bills at 10% of input in 64-token blocks, so a prompt under 64 tokens never hits; a prompt_cache_key raises the chance of a hit but does not guarantee one. Whether caching applies without the key, and the TTL, are not stated

Watch out

This board carried "no caching" here until 2026-08-29 on the strength of a rate missing from the pages it cited, retracted it, then left cached_in null for one pass. Both are now closed: the rate was on a third Mistral page all along, and it is $0.15

What we would use it for

Agentic and coding work with EU data residency

What this has cost, week by week

Output price at each refresh since 2026-07-30. A vendor change is the provider changing its price. Our correction means this board changed what it prints and the provider's charge did not move — the two are never merged, because publishing the second as the first would be a price rise that never happened.

our correction2026-08-06 · weights — Licence resolved against Mistral's models doc rather than left as 'check model card', which moved the row from partial to open. Mistral's terms did not change.
newly stated2026-09-03 · cached_in — $0.15 sourced from docs.mistral.ai/inference/pricing, a third Mistral pricing page that prints the cached-input column filled per model. Mistral's rate did not change — this board could not previously cite one, and the row carried null. The page is now cited by the row.
newly stated2026-09-24 · window — 256K window from Mistral's per-model page, newly cited.
