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

About this reference

This library reproduces the public llm-metadata snapshot: 592 model entries from 50 providers. This community maintained source does not independently verify every provider claim. Model identifiers belong to their listed provider; matching names from different providers remain separate entries. llm-metadata

Reference metadata does not establish Allgate availability or prices. Check the live model catalogue for current service and rates. Missing fields remain unknown. Source update dates are not substituted for release dates; retrieval dates are not model update dates. View live catalogue
