AI model API prices 2026

Prices per million tokens in US dollars, standard pay-as-you-go, before tax. Input is what you send (prompt, files, history); output is what the model writes — usually several times dearer.

One million tokens is roughly 750,000 English words. The same text in Arabic usually takes more tokens, so it costs more.
