Diraya-3B-Instruct-Ar is an Arabic reasoning-specialized language model fine-tuned from Qwen2.5-3B .
This model is part of the DIRA (Diraya Arabic Reasoning AI) collection, which focuses on enhancing the logical inference and mathematical reasoning capabilities of Arabic language models.
Base Model: Qwen2.5-3B via unsloth/Qwen2.5-3B-Instruct-unsloth-bnb-4bit
Model Type: Instruction-tuned causal language model
Architecture:
Training Approach:
GPRO LoRA Configuration:

This model was primarily fine-tuned on:
Figure: Composition of Rewards over Training Steps showing the evolution of model performance across different reward functions
The training utilized multiple reward functions to optimize different aspects of the model's performance:
As shown in the visualization, the model demonstrated consistent improvement across all reward dimensions throughout the training process. The upper values in rewards indicate higher-quality outputs that simultaneously satisfy multiple optimization criteria. This multi-objective training approach resulted in a model that not only produces correct answers but does so with clear, well-structured reasoning.
The model demonstrates strong performance on Arabic mathematical reasoning tasks, with particular strengths in:
