Arabic Prompt Guard

Fine-tuned from Meta's PromptGuard, adapted for Arabic-language LLM security filtering.


๐Ÿ“Œ Model Summary

calculate_statistics is a multi-class Arabic classification model fine-tuned from Meta's PromptGuard. It detects and categorizes Arabic prompts into:

  • Safe
  • Prompt Injection
  • Jailbreak Attack

This model enables Arabic-native systems to classify prompt security issues where other models (like the original PromptGuard) fall short due to language limitations.


๐Ÿ“š Intended Use

This model is designed for:

  • Filtering and evaluating LLM prompts in Arabic.
  • Detecting potential prompt injection or jailbreak attacks.
  • Enhancing refusal systems and LLM guardrails in Arabic AI pipelines.

Not intended for:

  • Non-Arabic prompts.
  • Highly nuanced intent classification.

๐ŸŒ Language Support

  • โœ… Arabic (Modern Standard Arabic) only
  • โŒ Not tested or reliable on English or other languages

๐Ÿ—๏ธ Model Details

  • Base Model: BERT (from Meta PromptGuard)
  • Architecture: Transformer (classification head)
  • Frameworks: Transformers + PyTorch
  • Task: Multi-class text classification
  • Classes: Safe, Injection, Jailbreak

๐Ÿงช Training Details

  • Dataset: Custom Arabic dataset based on translated Hugging Face datasets
    • 11,000 examples per class (33,000 total)
    • Carefully translated and cleaned using translation quality scores
    • All prompts and responses in Arabic
  • Training Setup:
    • 2 GPUs (22 GB each), ~80% utilization
    • Training time: ~30 minutes
    • Optimizer: Adam (default LR)
    • Techniques: Early stopping, gradient clipping

๐Ÿ“Š Evaluation

The model was evaluated on an Arabic-only test set with strong results:

  • โœ… Accuracy: ~97.3% F1-Score ~98%
  • Balanced performance across classes
  • Low confusion between safe vs. attack prompts

๐Ÿš€ Quick Usage (Test the Model)

You can easily load and test the calculate_statistics model using the Hugging Face pipeline interface:

from transformers import pipeline
