Cost against price

Arize AI costs $50. What does it cost to run?

We do not know which model Arize AI runs on, so here is the range. One seat doing the light workload, on the cheapest, middlemost and dearest models in the index.

If it runs onModelModel costLeft of $50
Cheapest priced modelQwen 3.7 Flash$0.13$50 (100%)
Middle of the rangeGemini 3.1 Pro$11$39 (79%)
Dearest priced modelClaude Fable 5$48$2.00 (4%)

A model, not an audit. This is what the intelligence would cost at that shape of work, not what Arize AI pays: we do not know its model, its real usage or what it has negotiated, and the figures exclude caching, batching and volume discounts. What the gap is worth is the product, and that is the thing to judge.
