§ 02 · Cost vs. quality

What accuracy do you need at your budget?

Map your cost per 1000 pages to available accuracy levels. Solutions on the green frontier line offer best quality at each price point.

Note: Accuracy figures are approximate and vary by document type. Position on frontier indicates best value at each price point. Open source solutions dominate the free tier, while Mistral offers the best cost-quality ratio for paid APIs.

§ 03 · Decision guide

By your situation.

Your data cannot leave your servers

Healthcare records, legal documents, GDPR/HIPAA requirements

→ Docling or PaddleOCR

100% local, no cloud dependencies, free

Docling: Best for tables/structure (financial docs)
PaddleOCR: Best for general text, multilingual

Processing 50k+ pages per month

Need best cost per page, cloud is acceptable

→ Mistral OCR

$0.001/page = $50 for 50k pages, 4x faster than local

At 100k pages/month: $100 vs $1,500 (Google/Azure)
50% batch discount available

Need guaranteed uptime and support

99.9% SLA required, enterprise contracts, phone support

→ Google Document AI or Azure

$1.50/1k pages, enterprise SLA, custom training

Azure: Better if already on Microsoft stack
Google: Better accuracy (89% vs 83%) in benchmarks

Extracting tables from invoices/reports

Need structured data output, CSV/Excel/DataFrame format

→ Docling

Free, TableFormer model, direct DataFrame export

Alternative: Mistral OCR (paid, faster, cloud-only)
GPT-5.4 works but requires manual parsing ($10/1k pages)
