Jev versus invoice OCR: a practical comparison
Invoice OCR turns pixels into strings and boxes. Jev accepts text only. Official models page: no image, audio, or video input. People confuse “understand this invoice” with extraction.
Unofficial. TypeSafe cookbooks: regex/LLM extract candidates, then Jev picks a span or checks a claim. docs.typesafe.ai.
Comparison scope
Line items, tax IDs, and totals should be parsed. Jev can ask “does this look like a duplicate of invoice 1044?” or “is the vendor name the same entity as the PO vendor?” on text you extracted.
Criteria that decide the architecture
| Axis | Jev (System One) | Invoice OCR |
|---|---|---|
| Pixels | Not accepted | Wins |
| Pick among candidate amounts | Choice over regex hits | OCR confidence |
| Date arithmetic | Code after extraction | Your AP system |
| Totals check | Code | Code |
Decision quality and control
Jaggedness: counting line items and comparing dates in the model is the wrong split. Official date cookbook: extract parts as Choice, assemble in code.
Integration trade-offs
OCR/vendor extract → candidates in state → Jev Choice/Noul → AP rules. Never POST a PDF.
TypeSafe’s public models page lists jev-1.13 at $0.042 per million input tokens with output tokens free — a vendor claim, not a jev.pro measurement. Confirm on the models page before you bid.
When each approach fits
Prefer Jev when
- You already have text and need a judgment
Prefer Invoice OCR when
- You still need characters from an image
OCR extract; Jev judge; ERP posts. Humans on low confidence.
What this page does not claim
-
Not an OCR vendor compare.
-
No claimed extraction F1.
-
Schema-safe output is not the same as factual correctness.
-
No independent bake-off numbers live here.
FAQ
Will Jev read a PDF? Not as bytes. Extract text first.
Handwritten invoices? That’s an OCR problem, then the same text pipeline.
