Training Process
The SecGPT model is open-source, including its base model, training code, and datasets. Users are encouraged to utilize these resources to develop their own cybersecurity models.
The model’s training involves:
- Using Baichuan-13B as the base model, selected for its language support and low memory usage.
- Fine-tuning with optimized code to minimize memory requirements, allowing training on standard GPUs like the 4090 series.
- Encompassing pre-training with a wide range of security-focused content.
Supervised learning datasets are constructed with the help of AI tools like ChatGPT to simulate various security scenarios and command understanding. Through a combination of expert input and real-world data, the model evolves to align closely with expert reasoning.
Model Improvement
SecGPT employs various strategies to refine its output quality, such as using precise prompts or allowing users to choose the best answer from multiple responses through Reinforcement Learning with Human Feedback (RLHF). These methods contribute to the model's ongoing development to meet user expectations and function efficiently within the cybersecurity field.
The SecGPT project, spearheaded by Yunqi Wuqi, is a significant step toward democratizing advanced cybersecurity tools and knowledge through open-source collaboration. Users and contributors are encouraged to participate and enhance SecGPT, fostering a more secure digital ecosystem.
For those with inquiries or contributions regarding the model, the project welcomes engagement through GitHub, inviting developers to contribute to the continuous improvement of SecGPT.
