Ara-Prompt-Guard
Arabic Prompt Guard
Fine-tuned from Meta's PromptGuard, adapted for Arabic-language LLM security filtering.
๐ 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.
๐ 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.
๐ Language Support
- โ Arabic (Modern Standard Arabic) only
- โ Not tested or reliable on English or other languages
๐๏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
๐งช 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
๐ Evaluation
The model was evaluated on an Arabic-only test set with strong results:
- โ Accuracy: ~97.3% F1-Score ~98%
- Balanced performance across classes
- Low confusion between safe vs. attack prompts
๐ 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
