Price per token

What it measures

List price per 1 million input and output tokens on OpenRouter, in US dollars. A token is a piece of text, usually smaller than a full word.

When it matters

It matters at volume. Models that think a lot spend more output tokens, so the price per token alone does not settle the bill. A cheap model on the list, if it writes a long chain of thought, can cost more for each finished task.

How to read it

Add up the input and output prices for the volume you expect, on OpenRouter. Models that think a lot spend more output tokens, and that part can outweigh the input price.
