The family includes, to our knowledge, the largest open Arabic-centric LLM trained from scratch at 70B parameters, and a competitive 8B-parameter variant among the evaluated open models. A custom Arabic-centric vocabulary enables efficient training and inference. In addition, an optimized architecture and training recipe yield highly compute-efficient training. With a substantially smaller token budget than comparable models, Jais 2 achieves strong Arabic performance on the benchmarks considered in this report and competitive English results. The models obtain leading results among the evaluated open models on OALL2 and AraGen. They also perform strongly on several culturally grounded Arabic benchmarks, including poetry, religion, cuisine, and dream interpretation, as well as in general tasks such as translation and summarization. We release the models in HuggingFace under a commercially permissive license. Jais 2 70B is also released as a chat app on the Web, iOS, and Android; it runs on Cerebras hardware, delivering up to 2,000 tokens per second, and enabling high-throughput Arabic-centric chat serving in our deployment setting. By uniting scale, linguistic diversity, cultural fidelity, openness, and speed, Jais 2 provides an open-weight foundation intended to support further research and development in Arabic-centric LLMs.", "url": "https://wpnews.pro/news/jais-2-a-family-of-arabic-centric-open-large-language-models", "canonical_source": "https://arxiv.org/abs/2608.13580", "published_at": "2026-08-17 04:00:00+00:00", "updated_at": "2026-08-17 04:13:59.178128+00:00", "lang": "en", "topics": ["large-language-models", "artificial-intelligence", "ai-research", "ai-products"], "entities": ["MBZUAI", "Cerebras", "Inception", "Jais 2", "HuggingFace", "OALL2", "AraGen"], "alternates": {"html": "https://wpnews.pro/news/jais-2-a-family-of-arabic-centric-open-large-language-models", "markdown": "https://wpnews.pro/news/jais-2-a-family-of-arabic-centric-open-large-language-models.md", "text": "https://wpnews.pro/news/jais-2-a-family-of-arabic-centric-open-large-language-models.txt", "jsonld": "https://wpnews.pro/news/jais-2-a-family-of-arabic-centric-open-large-language-models.jsonld"}}
