Frequently asked questions

Can jina-ocr-v1 be used in a commercial project?

No. License: CC BY-NC 4.0 - non-commercial use only; Jina AI issues a commercial license on request. A commercial product needs a different model or a separate agreement with the rights holder.

What hardware does jina-ocr-v1 need?

At minimum: One GPU with 16–80 GB — mid-size 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 jina-ocr-v1 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 jina-ocr-v1 and what does it cost?

The jina-ocr-v1 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.
