Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("Sheikhaei/llama-3.2-1b-en-zh-translator", torch_dtype="auto", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("Sheikhaei/llama-3.2-1b-en-zh-translator")

prompt = """### English:
The children were playing in the park.
### Mandarin:
"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=100, do_sample=False)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Training Data

This model was fine-tuned on a custom English–Mandarin parallel dataset containing ~640,000 sentence pairs. The source data was collected from Tatoeba and then translated and expanded using the Gemma-3-12B model.
