OCR and document models

Models that read text and layout from images and PDFs, including handwriting and complex tables.

What OCR and document models is

Modern document models return structure — reading order, tables, key-value pairs — rather than a flat string, which is what downstream automation needs.

How it works

Pipelines combine detection and recognition, or use a multimodal model that outputs structured markup directly. Confidence scores route low-certainty fields to human review.

Why it matters

It is the entry point for most enterprise document automation, and accuracy at this stage caps everything downstream.
