Meraj-Mini

Following the release of Arcee Meraj, our enterprise's globally top-performing Arabic LLM, we are thrilled to unveil Arcee Meraj Mini. This open-source model, meticulously fine-tuned from Qwen2.5-7B-Instruct, is expertly designed for both Arabic and English. This model has undergone rigorous evaluation across multiple benchmarks in both languages, demonstrating top-tier performance in Arabic and competitive results in English. Arcee Meraj Mini’s primary objective is to enhance Arabic capabilities while maintaining robust English language proficiency. Benchmark results confirm that Arcee Meraj Mini excels in Arabic, with English performance comparable to leading models — perfectly aligning with our vision for balanced bilingual strength.

Technical Details

Below is an overview of the key stages in Meraj Mini’s development:

1. Data Preparation: We filter candidate samples from diverse English and Arabic sources to ensure high-quality data. Some of the selected English datasets are translated into Arabic to increase the quantity of Arabic samples and improve the model’s quality in bilingual performance. Then, new Direct Preference Optimization (DPO) datasets are continuously prepared, filtered, and translated to maintain a fresh and diverse dataset that supports better generalization across domains.
2. Initial Training: We train the Qwen2.5 model with 7 billion parameters using these high-quality datasets in both languages. This allows the model to handle diverse linguistic patterns from over 500 million tokens, ensuring strong performance in Arabic and English tasks.
3. Iterative Training and Post-Training: Iterative training and post-training iterations refine the model, enhancing its accuracy and adaptability to ensure it can perform well across varied tasks and language contexts.
4. Evaluation: Arcee Meraj Mini is based on training and evaluating 15 different variants to explore optimal configurations, with assessments done on both Arabic and English benchmarks and leaderboards. This step ensures the model is robust in handling both general and domain-specific tasks.
5. Final Model Creation: We select the best-performing variant and use the MergeKit library to merge the configurations, resulting in the final Arcee Meraj Mini model. This model is not only optimized for language understanding but also serves as a starting point for domain adaptation in different areas.

With this process, Arcee Meraj Mini is crafted to be more than just a general-purpose language model—it’s an adaptable tool, ready to be fine-tuned for specific industries and applications, empowering users to extend its capabilities for domain-specific tasks.

Capabilities and Use Cases

Arcee Meraj Mini is capable of solving a wide range of language tasks, including the tasks as below:

1. Arabic Language Understanding: Arcee Meraj Mini excels in general language comprehension, reading comprehension, and common-sense reasoning, all tailored to the Arabic language, providing strong performance in a variety of linguistic tasks.

2. Cultural Adaptation: The model ensures content creation that goes beyond linguistic accuracy, incorporating cultural nuances to align with Arabic norms and values, making it suitable for culturally relevant applications.

3. Education: It enables personalized, adaptive learning experiences for Arabic speakers by generating high-quality educational content across diverse subjects, enhancing the overall learning journey.

4. Mathematics and Coding: With robust support for mathematical reasoning and problem-solving, as well as code generation in Arabic, Arcee Meraj Mini serves as a valuable tool for developers and professionals in technical fields.

5. Customer Service: The model facilitates the development of advanced Arabic-speaking chatbots and virtual assistants, capable of managing customer queries with a high degree of natural language understanding and precision.

6. Content Creation: Arcee Meraj Mini generates high-quality Arabic content for various needs, from marketing materials and technical documentation to creative writing, ensuring impactful communication and engagement in the Arabic-speaking world.
