We're open sourcing a 9B model that extracts structured data from documents at near-frontier performance. - 90.2% on our bench, vs Gemini 3.5 Flash at 91.3% - Leads extraction models like NuExtract3 (81.5%) - 9.5s p50 timings - Pass JSON schema

In their OCR 4 launch this week, Mistral shared a significantly lower score for Chandra 2 than you get from our repo or by running our public code. They also omitted Infinity Parser, which reports 87.6%, from their olmocr comparison.

This is lift (our open source extraction model) pulling structured data out of a messy 26-page contract.

I've been training OCR models for 2 years. The progress we've made in handwriting is astonishing - from barely readable to almost perfect transcription.

If you're blind, most PDFs are a garbled mess - and having one fixed can cost >$100. Our API now makes them usable for pennies.

Surya 2, which has 650M params and scores 83.3% on olmocr, is the most accurate small OCR model. One reason why is character tokenization. Constant compute over chars improves accuracy and model size.

Another slop benchmark - this time from LlamaIndex. If you fix a couple of glaring bugs in their scoring, Datalab goes from 65% to 93.6%.

OCR hallucinations poison downstream workflows. We built research-driven safeguards that reduce hallucinations to near-zero in our benchmark. And our word-level bboxes and confidence scores let you check any potential hallucinations that slip through.
