Massively Multilingual Adaptation of Large Language Models Using Bilingual Translation Data

Model Description

EMMA-500 Llama 3.1 8B is a state-of-the-art multilingual language model designed to improve language representation, especially in low-resource languages, through continual pre-training on the Llama 3.1 8B architecture. Leveraging the MaLA Corpus, which spans over 500 languages and is augmented with books, code, instruction data, and papers, EMMA-500 excels in multilingual tasks like commonsense reasoning, machine translation, and text classification.

Usage

You can use EMMA-500 for multilingual text generation. Below is an example to generate text using the model:

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "MaLA-LM/emma-500-llama3.1-8b-bi"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

input_text = "Once upon a time"
inputs = tokenizer(input_text, return_tensors="pt")
outputs = model.generate(**inputs)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Use Cases

Massively multilingual NLP tasks, e.g., machine translation
Performance regression on some tasks and high-resource languages
Cannot be used for real-world scenarios, esp. in high-stakes domains.
