Frequently asked questions

Can Unlimited-OCR be used in a commercial project?

Yes. License: MIT. It allows commercial use, but it is still worth having a lawyer review the license before launch.

What hardware does Unlimited-OCR need?

At minimum: Laptop or regular PC, up to 8 GB of VRAM — smaller versions. Without a GPU the model is not practical. You can calculate the exact VRAM for your model size and context in the hardware calculator.

Does Unlimited-OCR support Russian?

The model card does not list languages, so Russian support cannot be promised — it has to be tested on your own examples.

Where can I download Unlimited-OCR and what does it cost?

The Unlimited-OCR weights are open and free to download. You only pay for the hardware it runs on and for the setup. Source links are at the bottom of this page.
