Looking for the flagship model? Check out CyberQwen-14B-Security-V2 which achieves a 99.0% code patch rate on CWE-Bench v1 and 99.6% composite on ExploitGym. This repository contains the standalone full-weight Model V1 baseline.


πŸ“– Model Overview

CyberQwen-14B-Security is an enterprise-grade, defensive cybersecurity language model fine-tuned on top of Qwen/Qwen2.5-Coder-14B-Instruct. It is engineered specifically for:

  • Automated Vulnerability Eradication (CWE Repair): Ingesting SAST vulnerability alerts and automatically outputting drop-in, zero-vulnerability refactored code.
  • DevSecOps Alert Noise Suppression: Distinguishing real security defects from common scanner false positives with compliance justifications.
  • Security Operations Center (SOC) Threat Forensics: Analyzing Windows Event Logs, Sysmon, Auditd, and PCAPs to identify MITRE ATT&CK tactics, techniques, and IoCs.
  • Static Analysis AST Rule Compilation: Authoring valid, schema-compliant Semgrep rules for automated security pipelines.

In an objective 100-scenario enterprise cybersecurity benchmark, CyberQwen-14B achieved an overall composite defensive score of 84.0%, outperforming general-purpose frontier models on specialized defensive tasks.

🎯 Intended Uses & Scope

Direct Use Cases

  • Automated Code Remediation: Refactoring vulnerable source code to secure patterns without introducing regressions.
  • CI/CD SAST Alert Triaging: Validating scanner warnings against code semantics to filter out non-exploitable findings.
  • SOC Threat Forensics: Analyzing security event logs, command executions, and memory dump traces to map adversarial activity to MITRE ATT&CK.
  • Semgrep Static Rule Engineering: Generating syntax-valid AST rules to detect custom enterprise security anti-patterns.

Out-of-Scope Use

  • Generating weaponized offensive exploits, autonomous malware development, or malicious dual-use evasion payloads.
  • Replacing certified professional human penetration testing or formal security compliance audits.
