Jev is low-frontier not pareto optimal

I heard a lot about Jev - a new kind of model from TypeSafe. It’s available on OpenRouter. It’s quite low-cost: Input = 4.2c / MTok, Output = free. It only classifies or scores.

It’s not that accurate (75%) compared with DeepSeek V4.1 Flash (79%) or GPT 5.6 Luna (83%). ...
