Turn input, output and cache usage into a transparent cost breakdown.
Input categories are mutually exclusive. Cache writes apply on every request in this basic scenario. Tool, storage, batch, time-of-day and long-context rate adjustments are excluded.
Text tokens are only one part of a request. Chat formatting, tool definitions, images and hidden provider overhead can change the billed total.
Only numeric counts and workload settings move to the calculator or comparison. Your text and file names never go into the URL.
