Model Description
LLaMAX is a language model with powerful multilingual capabilities without loss instruction-following capabilities.
We collected extensive training sets in 102 languages for continued pre-training of Llama2 and leveraged the English instruction fine-tuning dataset, Alpaca, to fine-tune its instruction-following capabilities.
π₯ Effortless Multilingual Translation with a Simple Prompt
LLaMAX supports translation between more than 100 languages, surpassing the performance of similarly scaled LLMs.
def Prompt_template(query, src_language, trg_language):
instruction = f'Translate the following sentences from {src_language} to {trg_language}.'
prompt = (
'Below is an instruction that describes a task, paired with an input that provides further context. '
'Write a response that appropriately completes the request.\n'
f'### Instruction:\n{instruction}\n'
f'### Input:\n{query}\n### Response:'
)
return prompt
And then run the following codes to execute translation:
from transformers import AutoTokenizer, LlamaForCausalLM
model = LlamaForCausalLM.from_pretrained(PATH_TO_CONVERTED_WEIGHTS)
tokenizer = AutoTokenizer.from_pretrained(PATH_TO_CONVERTED_TOKENIZER)
query = "δ½ ε₯½οΌδ»ε€©ζ―δΈͺε₯½ζ₯ε"
prompt = Prompt_template(query, 'Chinese', 'English')
inputs = tokenizer(prompt, return_tensors="pt")
generate_ids = model.generate(inputs.input_ids, max_length=30)
tokenizer.batch_decode(generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0]
# => "Hello, today is a good day"
π₯ Excellent Translation Performance
LLaMAX3-8B-Alpaca achieves an average spBLEU score improvement of over 5 points compared to the LLaMA3-8B-Alpaca model on the Flores-101 dataset.
