Gemma 3 1B Arabic Grammatical Error Correction v1

Model Description

This model is a fine-tuned version of Google's Gemma 3 1B model, specifically trained for Arabic Grammatical Error Correction (GEC) by Alnnahwi. The model takes Arabic sentences as input and outputs their grammatically corrected versions.

Developed by: Bahjat Al Mostafa (Alnnahwi)
Base Model: google/gemma-3-1b
Task: Grammatical Error Correction
Language: Arabic
Version: 1.0.0
Organization: Alnnahwi

Quick Start

Installation

pip install transformers torch

Basic Usage

from transformers import pipeline, AutoTokenizer
import torch

MODEL_NAME = "alnnahwi/gemma-3-1b-arabic-gec-v1"

def extract_model_response(generated_text):
    """Extract just the model's response from the full generated text."""
    # Find the position after "model" marker
    model_marker = "\nmodel\n"
    if model_marker in generated_text:
        response_start = generated_text.find(model_marker) + len(model_marker)
        return generated_text[response_start:].strip()

    # Alternative format (in case formatting changes)
    alt_marker = "model\n"
    if alt_marker in generated_text:
        response_start = generated_text.find(alt_marker) + len(alt_marker)
        return generated_text[response_start:].strip()

    # If markers not found, return the original text
    return generated_text

# Initialize the tokenizer
tokenizer = AutoTokenizer.from_pretrained(MODEL_NAME)
# Add Gemma chat template manually
tokenizer.chat_template = """{% for message in messages %}{{'<start_of_turn>' + message['role'] + '\n' + message['content'] + '<end_of_turn>\n'}}{% endfor %}{% if add_generation_prompt %}{{'<start_of_turn>model\n'}}{% endif %}"""

# Device selection
if torch.backends.mps.is_available():
    device = "mps"
elif torch.cuda.is_available():
    device = "cuda"
else:
    device = "cpu"

# Create pipeline
pipe = pipeline(
    "text-generation",
    model=MODEL_NAME,
    tokenizer=tokenizer,
    device=device,
)

def correct_arabic_text(text):
    """Correct Arabic text using the fine-tuned model."""
    messages = [{"role": "user", "content": text}]
    prompt = tokenizer.apply_chat_template(
        messages, tokenize=False, add_generation_prompt=True
    )
    
    outputs = pipe(
        prompt,
        max_new_tokens=512,
        do_sample=False,  # Use greedy decoding for evaluation consistency
        temperature=None,
        top_p=None,
        top_k=None,
    )
    
    full_text = outputs[0]["generated_text"]
    return extract_model_response(full_text)

# Example usage with real outputs
test_inputs = [
    "كيف حالكي اليوم؟",
    "وجدنا سبعون حالة",
    "جاء في تسعة و سبعين سورة.",
    "لاكن ما رايكم",
]

for text in test_inputs:
    corrected = correct_arabic_text(text)
    print(f"Original: {text}")
    print(f"Corrected: {corrected}")
    print("-" * 50)

# Expected output:
# Original: كيف حالكي اليوم؟
# Corrected: كيف حالك اليوم؟
# --------------------------------------------------
# Original: وجدنا سبعون حالة
# Corrected: وجدنا سبعين حالة
# --------------------------------------------------
# Original: جاء في تسعة و سبعين سورة.
# Corrected: جاء في تسع وسبعين سورة.
# --------------------------------------------------
# Original: لاكن ما رايكم
# Corrected: لكن ما رأيكم؟
# --------------------------------------------------

Example Corrections

Input (Incorrect)	Output (Corrected)	Error Type
كيف حالكي اليوم؟	كيف حالك اليوم؟	Gender agreement
وجدنا سبعون حالة	وجدنا سبعين حالة	Number declension
جاء في تسعة و سبعين سورة.	جاء في تسع وسبعين سورة.	Number gender + spacing
لاكن ما رايكم	لكن ما رأيكم؟	Spelling + punctuation

Model Details

Training Data

• Dataset: Custom Arabic GEC dataset
• Training Epochs: 7
• Base Architecture: Gemma 3 1B parameters

Performance

• Designed for Modern Standard Arabic (MSA).
• Handles common grammatical errors.

Limitations

• Primarily trained on Modern Standard Arabic
• May not handle dialectical Arabic variations optimally
• Performance may vary with very long texts (>512 tokens)
• Context-dependent corrections may sometimes be imperfect

Use Cases

• Educational Tools: Helping Arabic learners with gender agreement and number declension
• Content Creation: Proofreading Arabic content for grammatical accuracy
• Text Processing: Preprocessing Arabic text for downstream NLP tasks
• Writing Assistance: Supporting writers with:
  • Proper number-noun agreement
  • Correct case declensions
  • Spelling standardization
  • Punctuation normalization
• Academic Writing: Ensuring grammatical correctness in formal Arabic texts

Training Details

• Fine-tuning Framework: Unsloth
• Base Model: Gemma 3 1B
• Training Epochs: 7
• Optimization: Memory-efficient fine-tuning techniques
