# AfriNLLB Dataset

AfriNLLB is a series of efficient multilingual open-source models for African languages. 
`AfriNLP/AfriNLLB-train` is one of two datasets we curated and used for training [AfriNLLB models](https://huggingface.co/collections/AfriNLP/afrinllb).
It comprises datasets from OPUS and Hugging Face, with additional data from GitHub and other publicly available online sources.
Moreover, `AfriNLP/AfriNLLB-train` is the authentic dataset used to create the knowledge distillation dataset [AfriNLLB-train-distilled](https://huggingface.co/datasets/AfriNLP/AfriNLLB-train-distilled)
More details about data sources and processing can be found in the [paper](https://arxiv.org/abs/2602.09373).


## Supported Languages

AfriNLLB supports 15 language pairs (30 translation directions), including Swahili, Hausa, Yoruba, Amharic, Somali, Zulu, Lingala, Afrikaans, Wolof, and Egyptian Arabic, 
as well as other African Union official languages such as Arabic (MSA), French, Portuguese, and Spanish. 
Our training data covers bidirectional translation between English and 13 languages, and between French and two languages (Lingala and Wolof).
