Strengths

Handles lines of Arabic text
Preserves punctuation well
Reconstructs spaces stably
Works best on scanned documents with clear text

Prioritizes:

Accuracy Consistency Stability Ease of deployment

⚠️ The model works with very high efficiency and is still in the testing phase, with ongoing work to improve the formatting. It is the most powerful OCR model ever.

⚠️ Known Limitations

⚙️ Implementation Methodology

The official inference pipeline and the modified pipeline differ significantly in processing strategy.

The modified implementation provides:

Better generation length control
Improved repetition handling
Cleaner post-processing
More stable decoding behavior

The official pipeline requires adjustments to fully suit structured Arabic OCR tasks.

For this reason, development continues using the optimized modified pipeline, with ongoing stability and formatting improvements.

⚠️ Chat Template Compatibility

The model sherif1313/Arabic-GLM-OCR-v1 may not be fully aligned with the default apply_chat_template behavior.

Improper usage may lead to:

Incorrect image token encoding
Minor text token misalignment
Reduced OCR extraction accuracy

It is recommended to verify prompt formatting and ensure correct image-text separation during preprocessing.

🔁 Generation Control Notice

Using excessively large generation limits such as:

may cause:

Repetitive outputs
Failure to stop at eos_token
Duplicate or unstructured text
Recommended settings:
