| Caveats | Not a :free variant: OpenRouter's model page says "The pricing shown on this page for Ling 3.1 Flash is zero, so you are not charged for prompt or completion tokens." No end date is stated for the $0 price. End rule: when OpenRouter stops listing this slug at $0, the row is retired to a dated negative row. |
No measured example — this row is evidence: documented: it states what the provider's own page advertised on the date shown, and this worker holds no credential to call it. The provider's documentation is the source: https://openrouter.ai/inclusionai/ling-3.1-flash
