What drives copywriting cost

Creative generation is output-dominated: a one-line brief produces paragraphs. Output rate is the number to compare, and the gap between tiers widens with length. Brand voice guidelines and examples are resent on every call and never change, which makes them the obvious candidate for caching.

For GPT 5.6 Sol specifically, that means output tokens cost 5.0x more than input, at $20.00 vs $4.00 per MTok. At this use case’s 500/2,000 token split, output accounts for 95% of the $0.0420 per-call cost.
