Open machine translation from South Slavic languages into East Slavic languages, published by Windstorm Labs on Hugging Face. This model covers several target languages; see the snippet for the target token.
- Task
- Translation: South Slavic languages → East Slavic languages
- Languages
- South Slavic languages zls, East Slavic languages zle
- Lineage
- OPUS-MT tc-big
- Format
- transformers (Marian), safetensors

Quality
Not yet scored. FLORES-200 has no test set for South Slavic languages → East Slavic languages, so this pair is outside the screening run.
How to run
Shell
pip install transformers sentencepiece torchPython
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
repo = "WindyTranslate/translate-tc-big-zls-zle"
tok = AutoTokenizer.from_pretrained(repo)
model = AutoModelForSeq2SeqLM.from_pretrained(repo)
# Several target languages: start each input with a target token such as >>xxx<<.
# The valid tokens are listed in the upstream model card.
batch = tok([">>xxx<< <South Slavic languages text>"], return_tensors="pt", padding=True)
print(tok.batch_decode(model.generate(**batch), skip_special_tokens=True)[0])Tested: Pattern run on 2026-10-01 against WindyTranslate/translate-tc-big-en-fr with transformers 4.57.6 and 5.18.0 on CPU ("Où se trouve la gare ?"); multi-target token prefix run against translate-tc-bible-big-mul-deu_eng_nld. Not run on every model individually.
