Model Description

LLaMAX2-7B is a multilingual language base model, developed through continued pre-training on Llama2, and supports over 100 languages. LLaMAX2-7B can serve as a base model to support downstream multilingual tasks but without instruct-following capability.

We further fine-tune LLaMAX2-7B on Alpaca dataset to enhance its instruct-following capabilities. The model is available at https://huggingface.co/LLaMAX/LLaMAX2-7B-Alpaca.

🔥 Effective Base Model for Multilingual Task

LLaMAX preserves its efficacy in general tasks and improves the performance on multilingual tasks. We fine-tune LLaMAX using only the English training set of downstream task, which also shows significant improvements in non-English. We provide fine-tuning LLaMAX models for the following three tasks:

• Math Reasoning: https://huggingface.co/LLaMAX/LLaMAX2-7B-MetaMath

• Commonsense Reasoning: https://huggingface.co/LLaMAX/LLaMAX2-7B-X-CSQA

• Natural Language Inference: https://huggingface.co/LLaMAX/LLaMAX2-7B-XNLI

    abstract = "Large Language Models (LLMs) demonstrate remarkable translation capabilities in high-resource language tasks, yet their performance in low-resource languages is hindered by insufficient multilingual data during pre-training. To address this, we conduct extensive multilingual continual pre-training on the LLaMA series models, enabling translation support across more than 100 languages. Through a comprehensive analysis of training strategies, such as vocabulary expansion and data augmentation, we develop LLaMAX. Remarkably, without sacrificing its generalization ability, LLaMAX achieves significantly higher translation performance compared to existing open-source LLMs (by more than 10 spBLEU points) and performs on-par with specialized translation model (M2M-100-12B) on the Flores-101 benchmark. Extensive experiments indicate that LLaMAX can serve as a robust multilingual foundation model. The code and the models are publicly available.",
