Every major AI provider bills the same way: you pay per token (roughly ¾ of a word), with separate rates for input (what you send) and output (what the model writes back). Output is usually 3–5× more expensive than input. A model listed at $5 / $25 per million tokens costs $5 for every million tokens you send and $25 for every million it generates.
Two discounts change the math dramatically: prompt caching cuts repeated input costs by up to 90% (critical for chatbots that resend conversation history), and batch processing takes ~50% off when you can wait for results. Our calculators account for both — most "how much will this cost" articles don't, which is why their estimates run 2–3× too high or too low.
