glm-5-3-flash vs ling-3.0-flash on classification: 1.2 quality points, 2.3× price.

Both measured on the same held-out classification suite: glm-5-3-flash at 1.000 and $0.0437, ling-3.0-flash at 0.988 and $0.0193 per thousand requests. Both figures come from the same held-out classification suite, 80 scored items, measured the same way — so the comparison is like for like.

Both were run against the same held-out items on the same day, so the gap is a property of the models rather than of the test. A 2.3× price difference at this quality distance is the whole decision.

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.
