> unable to make a bespoke model targeting the specific problem?

There is a fixed cost (and some maintenance) to e.g. fine tuning ModernBERT.

Maybe once you include all of that it might be a half-day to a day of engineering time to set everything up in a maintainable fashion.

For Jev, it takes all of 30 seconds of prompting. And it's not that much more expensive to deploy vs. a BERT model.
