Hi Joshua, Saw your thread looking for toolkits.
I run https://browser.mt/ to distribute Marian locally in the browser for privacy while running fast enough to be usable. Arguably the browser is more universal than the JVM these days. We're also aiming to improve the Marian developer experience: https://marian-project.eu/ which could grow to involve Apache. Marian already has a community of people making and using language packs: https://github.com/Helsinki-NLP/OPUS-MT-train https://huggingface.co/transformers/model_doc/marian.html I'd be keen to see these turn into larger continually updated packs. And of course we provide some of the data: https://paracrawl.eu/. To be clear, I'm not the lead maintainer of Marian but I do have an interest in making it more of a community project. And you can expect Marcin to show up in this thread if need be. Kenneth
