What a dollar buys
Answer in brief
Arithmetic
Tokens per dollar is one million divided by the price per million tokens, worked out once for input and once for output.
Input and output
A dollar buys far more input tokens than output tokens, because output is priced higher on nearly every listing.
Mix
What a dollar buys depends on your mix of input to output tokens, because the two are priced apart and the dollar is split between them.
Mix
A blended figure folds input and output into one number at a fixed mix, commonly three input tokens to one output token, and it is only right for work near that mix.
Units
A token is a piece of a word, and how many tokens a page becomes depends on the model’s tokenizer, so a million tokens is not the same amount of text on every model.
Input
A cached input rate is a lower price for the repeated opening of a prompt, so on repeat-heavy work the same dollar buys more input tokens.
Output
Reasoning tokens are output a model spends thinking before it answers, and they are billed at the output price, so they lower the visible answer you get for a dollar.
Scenarios
Tokens per dollar becomes useful when you divide it by the tokens one real task takes, which gives tasks per dollar.
Model choice
A smaller model returns many more tokens per dollar than the full model of its family, and choosing the size is the largest single lever on what a dollar buys.
GPUs
On a rented GPU, tokens per dollar is the tokens the machine produces in an hour divided by its hourly price, so it depends on how busy you keep the card.
