A distinct model architecture

The card specifies a decoder-only transformer with multi-head attention, RoPE and Squared-ReLU. It is a separate pretraining effort, not a Llama fine-tune.Jais 2 8B official model card

Keep existing deployments reproducible

Practical guidance. The smaller Jais 2 release is useful when reproducing a bilingual deployment built around an 8,192-token window. Keep its tokenizer and prompt template with the weights. Switching only the model name can change Arabic token use and message boundaries.
