Quality

Not yet scored. FLORES-200 has no test set for English → East Slavic languages, so this pair is outside the screening run.

How to run

Shell
pip install transformers sentencepiece torch
Python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

repo = "WindyTranslate/translate-tc-big-en-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<< Where is the train station?"], 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.
