15.9M-parameter Kraken OCR model beats VLMs hundreds of times larger on historical text

vanstriendaniel · x · 2026-09-03

Kraken PP-OCRv6, a specialist OCR model with just 15.9M parameters, ranks #4 on reading CER across a 2,165-page historical eval dataset — and #1 when long-s, ligatures, and case are preserved — outperforming general-purpose VLMs hundreds of times its size.

A strong data point for small specialist models in low-resource and long-tail digitization tasks.
