How to read a model's prices

Every maker prints 2 main prices: one for the tokens a model reads (input) and one for the tokens it writes (output), each per million tokens. Writing costs more on almost every model, so a job that reads a long document and writes a line pays mostly the input price, and a chat that writes paragraphs pays mostly the output price. The blend, 3 tokens read for each 1 written, is one figure for ranking models on everyday work.

The other prices lower or raise the bill. Text read again from a cache costs a fraction of the input price, so a long system prompt or document sent with every request gets cheaper after the first. Work that can wait a day costs about half on a batch where the maker offers one. Some models charge more for every token once a prompt passes a set length.

Thinking is billed as output, and the same text is not the same number of tokens on every model, so the price per token is only the start. Each job below is priced the way the cost calculator prices it, at its usual runs a day for 30 days; open one to change its size, or compare the model with another side by side.
