What is APPI?

The AI Purchasing Power Index (APPI) measures how much computational intelligence can be purchased for one US dollar. It tracks the cost efficiency of frontier AI language models over time.

APPI uses a standardized workload (70% input / 30% output tokens) to ensure fair comparisons across providers with asymmetric pricing structures.
