The model is based on Mistral-7B-v0.1 and was adapted to Arabic. The original tokenizer was replaced by a language-specific Arabic tokenizer with a vocabulary of 32768 tokens. The new embeddings were initialized with FOCUS. Additionally, we tuned just the embeddings for 100 steps before training the full model. The model was then trained on 8 billion Arabic tokens from uonlp/CulturaX with pure bfloat16 precision (no mixed precision). However, in the final annealing phase of the learning rate schedule, the model was again trained using bfloat16 mixed precision. More details and hyperparameters can be found in the paper.

The web-scale dataset used for pretraining and tokenizer training (uonlp/CulturaX) might contain personal and sensitive information. Such behavior needs to be assessed carefully before any real-world deployment of the models.
