The subscription is a different product

The chat apps are sold on a flat monthly fee: ChatGPT Plus and Pro on one side, a Claude subscription on the other. None of the numbers above apply to those. Compare them on what you get in the app, because per-token pricing has nothing to do with it.

Everything on this page is the API, where you pay for the words you send and the words you get back.

What this page can't tell you

Which one writes better, reasons better, or follows your instructions more closely. We run no benchmarks. The public ones move monthly and none of them predict how a model handles your work.

The way to settle it is to take one model from each side that both fit your budget and run your own real work through them. The filter will narrow the list to the ones you can afford.
