Live Translator translation models
Helsinki-NLP OPUS-MT models converted to CTranslate2 (float16 weights, otherwise unchanged) for the Live Translator desktop app, which downloads them from here at pinned commits with SHA-256 checks.
Each zip holds one translation direction: the CTranslate2 model, the SentencePiece models, opus_mt.json (upstream repo, revision, licence, target-language tag) and LICENCE.txt.
Licences and credit
All models are by the Language Technology Research Group at the University of Helsinki (OPUS-MT, Tiedemann & Thottingal 2020). Each keeps its own licence, listed below; CC-BY-4.0 models require this attribution and the note that they were converted.
