AI API Pricing
The normalized observation layer keeps endpoint identity, price fields, region, effective time, source and review state together.

API price lookup: check the date and source.
The current monthly AI Price Index replaces this paused research beta and uses a separate method and dataset. This archive retains input, cached-input, output and batch rates for ten model endpoints across four providers, observed on 24 August 2026. Check the linked provider source before budgeting; prices and access may have changed. For workload estimates, the separate token calculator uses unexpired starter rates or your own rates; it does not load this stale KAPI snapshot.

The prices are public; the index is not. These dated official-source observations are retained for historical inspection, not current quotes. The paused research program did not complete its thirteen-week continuity requirement. No official KAPI headline, ranking or cheapest-model claim was published. A missing price means “not published,” never zero.
Normalized price observations
API rates observed on 24 August 2026
USD per one million tokens unless marked otherwise. “Eligible” refers to the governed future index cohort. These historical rows are not available as current-price presets in the separate token calculator.
All 10 observations passed operator review and source-snapshot verification.2 DeepSeek rows remain index-ineligible because explicit US availability is unverified.
DeepSeek values use the documented weekday peak rate as a conservative estimate; Monday–Friday peak windows and all-hours off-peak conditions remain available in the public contract and calculator disclosure.

Long-context multipliers, prompt-cache write costs and provider-specific conditions are preserved in the public data and calculator disclosures. Prices are evidence, not a model-quality verdict.

The separate token calculator uses unexpired starter rates or your custom rates, then adds cache mix, retries, accepted-result rate and review labour. KAPI-backed current pricing remains paused.

What the beta proves—and what it deliberately withholds.
Source before claim
Each row cites an official provider surface and retains a checksum of the captured evidence.
Null is not zero
Unsupported batch, cache or regional facts remain null and cannot silently enter a calculation.
Price ≠ eligibility
A usable official USD price can coexist with an index exclusion when regional evidence is incomplete.
No hidden ranking
The official KAPI headline, rankings and shadow computation remain unpublished in this archived release.
Independent recomputation
The sealed release passed a separate calculation path before any public integration was prepared.
Versioned release
This table retains release kapi-shadow-2026-08-24. The separate token calculator has its own rate checks. Neither its starter rates nor the model pages make this historical table current.
Official evidence catalog

Machine-readable, redacted by design.
