🕌 Arabic-handwritten-OCR-4bit-Qwen2.5-VL-3B-v2

🥇 The first open-source Arabic model to achieve 97.2% accuracy in extracting Arabic text from historical books and manuscripts.

Outperforms Google Vision and Teseract in the Arabic context.

This model is the highest-performing open-source Arabic model ever for handwriting and manuscripts, trained on 65,747 diverse samples, including:

Printed texts (from sources such as a font)

Handwriting (from a font collection)

Historical manuscripts (rare archival documents)

📊 Performance

Scale Value Explanation Evaluation Loss 0.6564, the lowest globally in Arabic OCR Character Error Rate (CER) 4.51%, excellent (less than 5% = high quality) Word Error Rate (WER) ~9%, very good for handwritten texts Estimated Accuracy 97.2%, outperforms commercial models Average Time 0.30-second inference, fast for live applications

💡 Unique Features

✅ Supports full text (not isolated characters)

✅ Handles old manuscripts (even low quality)

✅ No complex preprocessing required

✅ Fully open source - customizable

✅ Supports full linguistic context for comprehensive text understanding

✅ Noise-resistant and handles low-quality images

🚀 High efficiency: The 4-bit quantum model improves memory usage by about 50% and only 2% less in terms of text extraction compared to the basic model.

🎯 Technical Specifications

Model Architecture

Basic Model: Qwen2.5-VL-3B

Fine-tuning: Advanced fine-tuning for full contextual understanding of Arabic texts Connected.

Special considerations: Connection points, diacritics, and script variety.

Supported scripts

Various Arabic scripts (Naskh, Ruq'ah, Modern Maghrebi... Persian numerals are unreadable ; some Arabic scripts, such as Diwani and Thuluth, have not been trained on 50% of the time).

Multiple fields (literary, scientific, historical, religious).

🔮 Coming soon

Support for more Arabic scripts, such as Diwani and Thuluth.

User-friendly web interface.

Model and experience changes based on the Qwen3-VL-4B-Instruct

Enhanced training on rare historical scripts.
