KJ-X Korean–Japanese Translation
KJ-X is a custom PyTorch encoder-decoder model for bidirectional Korean↔Japanese translation. The uploaded release contains inference exports and its SentencePiece tokenizer; training datasets and training checkpoints are not distributed.
Files
model_ema.pt: recommended FP32 EMA inference exportmodel_int8.pt: smaller CPU-only dynamic INT8 exportkjx.model,kjx.vocab,token_features.npz: tokenizer files
The model uses custom code from
gaon12/sion_translate and is not a Transformers
AutoModel checkpoint.
Usage
git clone https://github.com/gaon12/sion_translate.git
cd sion_translate
python -m pip install -e .
hf download gaon12/sion_translate --local-dir models/sion_translate
from kjx.inference import Translator
translator = Translator(
"models/sion_translate/model_ema.pt",
"models/sion_translate/kjx.model",
)
print(translator.translate(["안녕하세요."], target_language="ja", num_beams=4)[0])
print(translator.translate(["こんにちは。"], target_language="ko", num_beams=4)[0])
Use model_int8.pt for CPU inference with lower storage and memory requirements. Only load
PyTorch pickle-based artifacts from repositories you trust.
Evaluation
The GitHub repository includes a small, independently authored diagnostic JSONL covering both directions and provides a common scorer for KJ-X, LibreTranslate, Papago, Google Translation, DeepL, M2M100 418M, and NLLB-200. No universal quality claim is made from that small set.
Limitations
- Machine translations can omit, add, or reverse meaning.
- Proper nouns, short context-dependent utterances, specialist terminology, and long inputs need human review.
- Do not use unreviewed output for medical, legal, safety-critical, or certified translation.
- The custom architecture requires the repository code; hosted Transformers inference is not available out of the box.
