    Jev = $0.042/m input, output free Clef = $0.24/m input, no output price listed

    At 300 tokens per call, you'd get:

    One million decisions on Jev cost about $12.60. One million decisions on Clef cost about $72.

    Would probably make sense to self-host Clef, if you have the capability/resources. If not...

      It's weird to think of these kinds of models as having "output tokens". Cross-encoder approaches like Laya add a [MASK] marker per option, but nothing is generated the way an autoregressive transformer generates. It's one bidirectional pass over your input, then a small head scores each option, so you wouldn't really pay for output as much as only input
