What is Jais 30B?
Jais 30B is a 30-billion-parameter bilingual Arabic-English large language model developed by Inception (a G42 company), Mohamed bin Zayed University of Artificial Intelligence (MBZUAI), and Cerebras Systems. Released in August 2023 with major upgrades through the Jais Family series, it's the most advanced open-source Arabic LLM ever released.
It is released under Apache 2.0, making it 100% free for commercial use.
Why Jais Is Trending in 2026
As the MENA (Middle East and North Africa) AI market grows rapidly, Jais has become the go-to choice for Arabic-language AI applications. With over 400 million Arabic speakers globally historically underserved by Western LLMs, Jais fills a critical gap.
The newer Jais Family includes 6.7B, 13B, 30B, and 70B variants, with strong instruction-following and chat capabilities.
Key Features and Capabilities
Jais 30B supports fluent Arabic generation across all major dialects (MSA, Egyptian, Gulf, Levantine, Maghrebi), bilingual reasoning, instruction following, code generation, and mathematical reasoning. It was trained on 1.6 trillion tokens (roughly equal Arabic and English).
Who Should Use Jais?
Jais is built for MENA-focused startups, Arabic content platforms, government AI initiatives, education tech in the Arab world, financial services in the Gulf, and research institutions.
Top Use Cases
Real-world applications include Arabic chatbots, content generation in MSA and dialects, Quran and Islamic studies AI, Arabic-English translation, Gulf region customer support, education tools for Arabic learners, and government services automation.
Where Can You Run It?
Jais runs on Hugging Face Transformers, Ollama, vLLM, and Inception's hosted API. The 30B model needs ~60 GB VRAM at BF16; 4-bit quantization brings it to ~18 GB for consumer GPUs.
How to Use Jais (Quick Start)
Easiest: ollama pull jais. For Hugging Face: core42/jais-30b-chat-v3. Use the bilingual chat template; Jais responds fluently in whichever language you prompt it in.
When Should You Choose Jais?
Choose Jais for any application targeting Arabic-speaking users. For frontier multilingual quality including non-Arabic languages, also consider Qwen 2.5-72B, Mistral 8x22B, or Llama 3.1-70B.
Pricing
Jais is completely free under Apache 2.0.
