Leopo1d/OpenVul-Qwen3-4B-SFT-ep5

Leopo1d/OpenVul-Qwen3-4B-SFT-ep5 is a Qwen3-based language model fine-tuned for vulnerability detection in C/C++ code. This model specializes in identifying security flaws by analyzing inter-procedural contexts rather than isolated functions. It was trained using rejection sampling on high-quality vulnerability reasoning Chain-of-Thought (CoT) data to establish security expertise and instruction-following capabilities. Its primary use is for precise, evidence-based analysis of code vulnerabilities, focusing on Common Weakness Enumeration (CWE) standards.
