Jais 3 launches as six open Arabic-native models, from 0.9B to 375B, plus Jais Speech

MBZUAI's Institute of Foundation Models and Inception42 released Jais 3 on Oct 15: six open language models from 900M to 375B parameters (the flagship is a mixture-of-experts model running 23B per token), all with a 512K context window, plus Jais Speech for Arabic speech recognition across dialects. Built on IFM's K2 Horizon models, they're on Hugging Face under Apache-2.0 with vLLM and SGLang support. In IFM's own Arabic tests, the 7B model's average rises from 56.4 for its K2 Horizon base to 79.6. IFM is also releasing the benchmarks and code it used.
How you’d use it: Run an open model that writes, transcribes and follows instructions in Arabic dialects, sized to your hardware.
