Historical Chart

Early history is modeled from price-impact factors until enough real daily source snapshots exist.

Price Impact Factors

The core driver is compute affordability. Technology progress and supply expansion tend to push TPI down and TPX up. Compute scarcity or frontier-demand congestion can push TPI up and TPX down.

Regional sleeve mix

Mixed effect

Global TPI moves when weight shifts between US/North America and China baskets.

Technology progress

Can lower TPI

Global improvements in chips, inference software, caching, routing, and model efficiency tend to make tokens cheaper over time.

Compute scarcity

Can raise TPI

Global GPU bottlenecks, premium frontier demand, and reliability requirements can push inference prices up.

Global price competition

Can lower TPI

Cross-region competition and open-model pressure tend to reduce list prices over time.

FX and infrastructure costs

Mixed effect

Currency changes, GPU supply, and serving efficiency affect normalized USD prices.

Inclusion Rule

Constituents must have observable API pricing, stable availability, current mainline model status, commercial relevance, and a reliable source trail. Newly detected models go through watchlist review before joining an index.

Weighting Method

Weight rules are public: market-share signals are preferred, with revenue and adoption proxies used when stable share data is unavailable. Exact live constituent weights are summarized publicly at an appropriate reporting frequency.

Constituent Models

Constituents and price sources are disclosed for transparency. Exact live constituent weights are calculated from market-share, revenue, and adoption signals and will be summarized publicly at an appropriate reporting frequency.
