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: USD. 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
