It's got the word 'open' everywhere, yet it doesn't show any documentation about self-hosting. Functionally, it might as well be closed-sourced sass using PaddleOCR-VL.
But being open-weight model, there is no vendor-lockin. if you stop liking the api endpoint, or we were to increase prices, just run the model yourself elsewhere. So in a sense it is open. At least more than openAI or openrouter :)
