Frequently asked questions

Can MonoQwen2-VL (LightOn) be used in a commercial project?

Yes. License: Apache 2.0. It allows commercial use, but it is still worth having a lawyer review the license before launch.

What hardware does MonoQwen2-VL (LightOn) 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 MonoQwen2-VL (LightOn) 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 MonoQwen2-VL (LightOn) and what does it cost?

The MonoQwen2-VL (LightOn) 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.
