VERSIONED EVIDENCE

LLM API Pricing Data & Calculation Methods

Review the official pricing sources, verification dates, assumptions, and formulas behind every LLM API comparison and workflow-cost estimate.

Catalog updated2026.07.27Schema v1

Catalog contract

Every published row references one model, provider, pay-as-you-go route, source, and verification date. Price and specification fields require first-party sources; benchmark fields require an explicitly labeled independent source.

Market Map formula

The first chart displays the estimated blended price directly per 1M tokens: 90% input and 10% output, with half of input tokens using the cached-input price. The second chart multiplies independent Terminal-Bench v2.1 cost per task and pass@1 by one selected monthly attempt volume. It is benchmark-specific, not a provider quota or universal production acceptance rate.

Cost & Routing formula

Base tokens are increased by retries and failed calls, then allocated across the primary mix and fallback share. Cost per accepted request uses the entered acceptance rate.

Compatibility evidence

The atlas summarizes documented custom-endpoint paths. The browser check is deliberately narrow: one non-streaming chat-completions request and a choices-shape check. CORS failures remain inconclusive.

How every value is labeled

Official field means a price, model status, or limit copied from a linked first-party source. Independent benchmark means a published third-party score or measured cost stored with its exact benchmark variant and verification date. Derived metric means arithmetic over those fields using the published formula. User assumption means a workload input supplied in Cost & Routing. Browser observation exists only after you run the basic endpoint check in the current session.

Not included

Non-Terminal-Bench quality scores, subscription quotas, negotiated discounts, taxes, batch pricing, regional surcharges, human review, and provider uptime are not normalized in this version.

Versioned data downloads

Machine-readable files preserve official pricing, modeled assumptions, and independent benchmark evidence as separate layers.
