Why do output tokens cost more than input tokens?

Reading your prompt can be done in parallel, while writing an answer happens one token at a time, so each output token takes more compute. That's why every tier prices output higher: Flash $3.40 vs $1.60, Max $3.80 vs $1.80, Heavy $4.40 vs $2.00 per 1M tokens.

Practical effect: long answers and long reasoning cost more than long prompts. Asking for concise answers is one of the easiest ways to save.
