AI Model Costs
Compare sticker price, token efficiency, and real task cost across frontier models
The adjustment, model by model
The gray bar is the published token price applied to a fixed 2M-input + 1M-output workload.
The purple bar applies the model's AA token-usage multiplier. If purple is below gray, the model is token-efficient; if purple is above gray, it burns more tokens than the median model.
Why sticker price moves
Token efficiency compares how many tokens each model uses on the Artificial Analysis Index against the median model.
A model at 1× is exactly median. A model at 2× uses half as many tokens as the median, so it is twice as token-efficient. A model at 0.5× uses twice as many tokens as the median.
The vertical scale is logarithmic, so each gridline is one doubling or halving of token efficiency.
Quality per task dollar
Effective cost combines the price sheet with observed token usage, so it approximates what a task costs in practice rather than only what tokens cost in isolation.
The strongest cost story is not the cheapest model overall. It is which models sit high on IQ while staying far to the right on the reversed cost axis.
