What drives blog writing cost

The most output-heavy use case tracked here. A brief of a few hundred tokens produces an article of several thousand, so output pricing is essentially the entire cost and input rate is noise. Generating section by section rather than whole-article gives you more control over both quality and spend, at the cost of more calls.

For o3 Mini specifically, that means output tokens cost 4.0x more than input, at $4.40 vs $1.10 per MTok. At this use case’s 1,000/8,000 token split, output accounts for 97% of the $0.0363 per-call cost.
