Sources

Every primary-source citation that backs a verified value on this site. 19 unique URLs are indexed below. Each entry records when it was last retrieved and a short note describing what was used.

This page is the audit trail. If a metric appears on a model or provider page, the source it came from is listed here — and conversely, if a metric is rendered as Data not yet verified., no citation exists for it yet. Pricing sources are classified as first-party pricing reference (the model creator's own pricing page) or hosted pricing reference (a hosting platform's page). Both are reference values, not live quotes. For per-attempt outcomes (including blocked retrievals), see /coverage. Each citation below pairs the retrieval date with a freshness chip; sources that have aged out of the standard window appear on the reverification queue for a manual re-check — they are never auto-fetched. For the methodology behind these citations, see /research/source-verification-methodology and the reference at /docs/data-verification.
