New SLMs boost machine translation for 19 African languages

Researchers have developed TranslatePsy-AfriSLM, a new suite of open-source machine translation resources specifically for 19 Sub-Saharan African languages. This initiative addresses the significant gap in AI development for African languages, where existing large language models often underperform. The project includes curated parallel data, synthetic data tailored for African languages, and a series of fine-tuned small language models (SLMs). These SLMs, even with as few as 0.8 billion parameters, demonstrate superior performance compared to much larger models like TranslateGemma-27B and Qwen3.5-122B-A10B, particularly after employing a quality-estimation filtering technique that removes low-quality training data.
