+
+## Introduction
+
+We introduce **Babel**, a multilingual LLM that covers the top 25 languages by number of speakers, including English, Chinese, Hindi, Spanish, Arabic, French, Bengali, Portuguese, Russian, Urdu, Indonesian, German, Japanese, Swahili, Filipino, Tamil, Vietnamese, Turkish, Italian, Javanese, Korean, Hausa, Persian, Thai, and Burmese. These 25 languages support over 90% of the global population, and include many languages neglected by other open multilingual LLMs. Unlike traditional continued pretraining approaches, Babel expands its parameter count through a layer extension technique that elevates Babel's performance ceiling.
+
+We introduce two variants:  
+- **Babel-9B**, designed for efficient single-GPU inference and fine-tuning  
+- **Babel-83B**, which sets a new standard for open multilingual LLMs  
+
+Extensive evaluations on multilingual tasks demonstrate its superior performance compared to open LLMs of comparable size. In addition, using existing supervised fine-tuning datasets, Babel achieves remarkable performance, with **Babel-9B-Chat** leading among 10B-sized LLMs and **Babel-83B-Chat** setting a new standard for open LLMs, performing comparably to GPT-4o on certain tasks.
+
+This page introduces the **Babel-83B-Base** model
+
+
+## Evaluation
+
+We employ multilingual tasks across several categories:
+
+1. **World Knowledge:**  
+   MMMLU ([OpenAI 2024](https://huggingface.co/datasets/openai/MMMLU)), a human-translated version of MMLU ([Hendrycks et al. 2021](https://arxiv.org/abs/2009.03300)) available in 14 languages. For languages not covered, we use Google Translate ([Google Translate API](https://translate.google.com/)) to generate translations. Additionally, we include M3Exam ([M3Exam](https://arxiv.org/abs/2306.05179)), which consists of authentic human exam questions collected from various countries, covering multiple subjects and educational levels.
+
+2. **Reasoning:**  
+   MGSM ([Shi et al. 2022](https://arxiv.org/abs/2210.03057)) and XCOPA ([Ponti et al. 2020](https://aclanthology.org/2020.emnlp-main.185/)).
+
+3. **Understanding:**  
+   XNLI ([Conneau et al. 2018](https://arxiv.org/abs/1809.05053)).
+
+4. **Translation:**  
+   Flores-200 ([NLLB Team 2022](https://arxiv.org/abs/2207.04672)).

+## Acknowledgement
+We would like to thank Guanzheng Chen for assisting with the implementation of the training codebase. Our special thanks go to our professional and native linguists—Tantong Champaiboon, Nguyen Ngoc Yen Nhi, and Tara Devina Putri—who contributed to building, evaluating, and fact-checking our sampled pretraining dataset. We also appreciate Fan Wang, Jiasheng Tang, Xin Li, and Hao Zhang for their efforts in coordinating computing resources.
