Translation Prompt

The model has no chat template. Use a raw completion prompt with English language names, tokenized without special tokens:

text

Translate this from <source language name> to <target language name>:
<source language name>: <source language sentence>
<target language name>:

Use with mlx

pip install mlx-lm

python

from mlx_lm import load, generate

model, tokenizer = load("mlx-community/MiLMMT-46-4B-v0.1-6bit")

text = "Translate this from Chinese (Simplified) to English:\nChinese (Simplified): 我爱机器翻译\nEnglish:"
prompt = tokenizer.encode(text, add_special_tokens=False)

response = generate(model, tokenizer, prompt=prompt, verbose=True)
