PolyLM多语言文本生成模型（PolyLM-文本生成模型-多语言-13B-演示）

模型简介

PolyLM是一个通晓多种语言的大规模语言模型，涵盖中文、英文、西班牙语、法语、德语、俄语、葡萄牙语、意大利语、阿拉伯语、日语、韩语、泰语、越南语和印尼语等18个语言。该模型可以应用于对话问答、文本生成、机器翻译和情感分析等领域，能够自动生成高质量的多语言文本，从而为跨语言、文化的交流提供便利。

Abstract in English

Large language models (LLMs) demonstrate remarkable ability to comprehend, reason, and generate following nature language instructions. However, the development of LLMs has been primarily focused on high-resource languages, such as English, thereby limiting their applicability and research in other languages. Consequently, we present PolyLM, a multilingual LLM trained on 640 billion (B) tokens, avaliable in two model sizes: 1.7B and 13B. To enhance its multilingual capabilities, we 1) integrate bilingual data into training data; and 2) adopt a curriculum learning strategy that increases the proportion of non-English data from 30% in the first stage to 60% in the final stage during pre-training. Further, we propose a multilingual self-instruct method which automatically generates 132.7K diverse multilingual instructions for model fine-tuning. To assess the model’s performance, we collect several existing multilingual tasks, including multilingual understanding, question answering, generation, and translation. Extensive experiments show that PolyLM surpasses other open-source models such as LLaMA and BLOOM on multilingual tasks while maintaining comparable performance in English.

Our models, alone with the multilingual instruction data, are available at Github and Huggingface.
