Pick DeepSeek-OCR if you want DeepSeek’s MIT LICENSE file, a GitHub repo with 24,079 stars, and the older ~3.3B optical- compression card (config context 8,192). Both are official org cards, not community fine-tunes. Vendor benches stay vendor. We have no sourced bake-off.

FAQ

Which is more accurate on long PDFs?

We do not rank them. Unlimited-OCR-2’s MPDocBench / MarathonDocBench lines stay vendor. DeepSeek-OCR’s paper claims stay vendor. See the entity pages.

Is Unlimited-OCR-2 a fine-tune of DeepSeek-OCR?

The Baidu card thanks DeepSeek-OCR as prior work. We did not open a statement that the weights are a third-party fine-tune. Treat it as Baidu’s official card.

Why this pairing?

There was no OCR model page on this site. Unlimited-OCR-2’s README names DeepSeek-OCR. The thin DeepSeek-OCR page exists so the vs URL can cite both sides.

Can either replace Acrobat Pro OCR?

Not independently tested. PDF toolboxes on this site stay on Adobe Acrobat alternatives (Stirling-PDF, PDF Arranger, Okular).
