Methodology and the 14-day process: the frozen RFC.
PRICING CLARITY
List prices per 1M tokens (input/output) published on an official page without login.
https://mistral.ai/pricing/api/Captured 2026-08-28
Price unit is unambiguous (per 1M tokens; input vs output separated).
https://mistral.ai/pricing/api/Captured 2026-08-28
Page states an effective/updated date (attributable to a snapshot).
https://mistral.ai/pricing/api/We extracted the complete rendered text of the pricing page and found no date of any kind, and we found no dated archive of past pricing.

Cached/batch/discount tiers (where offered) published officially.
https://mistral.ai/pricing/api/Captured 2026-08-28
Promotional pricing labeled as promotional (with end date if time-limited).
https://mistral.ai/pricing/api/One offer is labelled as available for a limited period, but we found no end date published for it. The criterion requires the end date where the offer is time-limited.

SPEND OBSERVABILITY
Usage available per model in console/API (not only aggregated).

Token counts (input/output) reported alongside spend.
https://docs.mistral.ai/admin/billing-usage/usage-limitsCaptured 2026-08-28

Usage/cost export exists (CSV/API) without premium tier.
https://docs.mistral.ai/admin/security-access/admin-apiA usage export exists, but your documentation states the Admin API is available on Enterprise plans. The criterion requires an export available without a premium tier, so we could not score it MET; we found no documented CSV path outside that tier.

Near-real-time spend tracking (sub-hour refresh) exists.

Usage CSV/API and invoice are reconcilable without manual mapping.

Billing docs/invoices available via API for automation.
https://docs.mistral.ai/admin/security-access/admin-apiThe only documented invoice retrieval path we found is a console click to download a PDF, and the Admin API's own enumerated scope does not include invoices. Cost data is available through the usage endpoint, but that is not an invoice document.

DISCLOSURE
Data-use-for-training policy is clearly published.
https://legal.mistral.ai/terms/commercial-terms-of-serviceCaptured 2026-08-28
Energy/environmental information is clearly published (yes/no — never a grade).
https://mistral.ai/news/our-contribution-to-a-global-environmental-standard-for-ai/Captured 2026-08-28
Pricing/support changes are communicated before taking effect.
https://legal.mistral.ai/terms/commercial-terms-of-serviceYour terms commit to thirty days' notice for updates to the Terms themselves. We could not find a clause committing to advance notice of a price change, since pricing lives on a page outside the Terms. If such a commitment exists, we will re-score.
