It leverages pre-trained weights from **meta-llama/Llama-3.1-8B-Instruct**, and has been fine-tuned using the **google/code_x_glue_cc_defect_detection** dataset. This dataset contains a variety of labeled code snippets, each annotated with different types of vulnerabilities such as buffer overflows, SQL injections, and other security issues.28 29The model performs **feature extraction** on code snippets and classifies them based on whether they exhibit vulnerable behavior. The goal is to provide an automated assistant that can detect potential vulnerabilities in code, making it easier for developers and security professionals to identify and address security risks early in the development process.30 31- **Model Type:** GRPO-based model for defect detection32- **Base Model:** meta-llama/Llama-3.1-8B-Instruct33- **Pipeline Tag:** feature-extraction34- **Fine-tuned from:** meta-llama/Llama-3.1-8B-Instruct35- **License:** Boost Software License 1.036- **Primary Task:** Vulnerability detection in code37- **Training Dataset:** google/code_x_glue_cc_defect_detection38- **Language(s):** English (Programming code in English)39- **Metrics Used:** Accuracy40 41#### Model Architecture42 43The model uses a variant of the transformer architecture, which has been fine-tuned for vulnerability detection in code. It processes code snippets and uses learned patterns from the dataset to classify code as either vulnerable or not. The model uses **GRPO (Generalized Reinforcement Pretrained Optimization)**, which helps the model better adapt to the task of defect detection, providing improved performance compared to standard fine-tuning techniques.44 45The model employs a **tokenization approach** that is well-suited for code, converting the raw code into tokenized representations that are then processed by the transformer architecture. The training uses **mixed-precision training** (fp16), which reduces memory usage and speeds up training without compromising accuracy.46 47#### Performance48 49The model has been evaluated on the **google/code_x_glue_cc_defect_detection** dataset, where it showed promising results with an accuracy of **85%** on detecting vulnerabilities across various code types. This performance was achieved by evaluating the model on a test set of labeled code snippets, where it was able to successfully identify vulnerable code patterns.50 51#### Practical Use Cases52 53- **Code Security Analysis:** Automatically detecting potential security vulnerabilities within code to ensure that software is secure before deployment.54- **Developer Assistance:** Helping developers identify areas in their codebase that could be potential vulnerabilities, reducing manual inspection time and improving overall code security.55- **Automated Code Reviews:** Integrating the model into code review processes to flag potential vulnerabilities as part of the continuous integration (CI) pipeline.56 57---58 59This detailed version of the **Model Details** section should provide comprehensive information about the model's description, architecture, performance, and use cases.

Fine-tuned from meta-llama/Llama-3.1-8B-Instruct, it has been specifically trained on the google/code_x_glue_cc_defect_detection dataset, which contains annotated code samples with identified vulnerabilities like buffer overflows, SQL injections, and more.64 65This model is designed to classify code snippets based on their vulnerability, helping developers and security experts automatically detect and address potential security risks within their software. It performs feature extraction and classification tasks, leveraging the power of the GRPO (Generalized Reinforcement Pretrained Optimization) framework for better optimization and performance in defect detection tasks.66 67The model operates by processing raw code into tokenized representations, then using its pre-trained transformer architecture to predict the presence of vulnerabilities with high accuracy. By utilizing mixed-precision training (fp16), the model achieves a balance of performance and memory efficiency, making it suitable for large-scale code analysis.68 69- **Developed by:** [ilyas DAHAOUI]70- **Model type:** [Transformer-based Model for Code Vulnerability Detection]71- **Language(s) (NLP):** [(Code-based vulnerabilities in various programming languages like Python, C++, JavaScript, etc.]72- **License:** [MIT License]73- **Finetuned from model [ meta-llama/Llama-3.1-8B-Instruct]:** [GRPO]74- 75### Direct Use76 77<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->78 79[This model is designed to identify potential vulnerabilities in code by analyzing programming syntax, logic, and structure.
