The last 22.5 points of classification quality cost 16×.

On Potion's measured classification suite, one model scored 1.000 at $0.0437 per thousand requests while another scored 0.775 at $0.0027. Both figures come from the same held-out classification suite, 80 scored items, measured the same way — so the comparison is like for like.

The premium buys 22.5 quality points on this suite. Whether that is worth 16× the price depends on what a failure costs you: at high volume with a cheap retry, it usually is not; on work that ships unreviewed, it can be.

Someone is paying the difference. If that is you, the question worth asking is which of these two numbers your workload actually needs — and this is the measurement that answers it.

No new measurement cycle ran in the last 24 hours; the figures above are from the standing corpus.

The current numbers live on the measured answers; the method is public.
