HPLT v2.0 Ukrainian→English — CTranslate2 int8

HPLT/translate-uk-en-v2.0-hplt_opus (Marian transformer-base, CC-BY-4.0) converted to CTranslate2 int8 for on-device use in the Mova offline translation app. Weights are unchanged from upstream; only the format was converted (the id-ordered .vocab was regenerated as the Marian YAML vocabulary the converter expects — verified token-for-token against the SentencePiece model).

Quick facts

~81 MB on disk, ~110 MB resident RAM (CTranslate2 int8, CPU)
Use with ctranslate2.Translator + the upstream SentencePiece model, beam_size=4

Evaluation note

We validated this conversion on a small corpus only — 60 FLEURS parallel sentences: chrF2 56.26 (uk→en), versus NLLB-600M-int8 58.10 on the same sentences. This is a sanity check that the conversion preserved quality, not a comprehensive benchmark. For proper evaluation numbers see the upstream HPLT v2.0 release and paper.
