Paper: NiuTrans.LMT: Toward Inclusive and Scalable Multilingual Machine Translation with LLMs
Github: LMT

LMT-60 is a suite of Chinese-English-centric Multilingual Machine Translation (MMT) models trained on 90B tokens mixed monolingual and bilingual tokens, covering 60 languages across 234 translation directions and achieving SOTA performance among models with similar language coverage. We release both the CPT and GRPO versions of LMT-60 in four sizes (0.6B/1.7B/4B/8B). All checkpoints are available:

Models	Model Link
LMT-60-0.6B-Base	NiuTrans/LMT-60-0.6B-Base
LMT-60-0.6B	NiuTrans/LMT-60-0.6B
LMT-60-1.7B-Base	NiuTrans/LMT-60-1.7B-Base
LMT-60-1.7B	NiuTrans/LMT-60-1.7B
LMT-60-4B-Base	NiuTrans/LMT-60-4B-Base
LMT-60-4B	NiuTrans/LMT-60-4B
LMT-60-8B-Base	NiuTrans/LMT-60-8B-Base
LMT-60-8B	NiuTrans/LMT-60-8B

Our supervised fine-tuning (SFT) data are released at NiuTrans/LMT-60-sft-data

Quickstart

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "NiuTrans/LMT-60-8B"

tokenizer = AutoTokenizer.from_pretrained(model_name, padding_side='left')
model = AutoModelForCausalLM.from_pretrained(model_name)

prompt = """Translate the following text from English into Chinese:
English: The concept came from China where plum blossoms were the flower of choice.
Chinese:"""
messages = [{"role": "user", "content": prompt}]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(**model_inputs, max_new_tokens=512, num_beams=5, do_sample=False)
output_ids = generated_ids[0][len(model_inputs.input_ids[0]):].tolist() 

outputs = tokenizer.decode(output_ids, skip_special_tokens=True)

print("response:", outputs)
