Source pricing and conditions
Costs retain the source structure, tiers and conditions. These snapshot values are not Allgate API quotes. Cost currency and provider billing currency are separate fields; each defaults to USD when absent.
Cost currency: USD · Provider billing currency: CNY. Input, output, reasoning, cache and audio token fields use the cost currency per million tokens. Explicit per-image, per-second and per-10,000-character fields retain their named units and resolution conditions.
Tier prices apply above the stated size. When tiers exist, source logic ignores the legacy context_over_200k field. Scheduled prices override stated fields within their window; omitted fields inherit base prices. Source pricing schema
Cost currency differs from provider billing currency. The source may contain upstream estimates; no currency conversion has been applied here.
- pricing: "stepfun" bills in CNY but 1 model(s) still carry upstream USD estimates; add cost overrides with "currency": "CNY"
No cost object is specified in this source entry.
Model metadata
Original source field names and values are preserved. False, zero, empty objects and missing values remain distinct. Missing capabilities are not inferred from a name, category or related version.
