Cogent Security has released VR-1.1, a frontier reasoning model designed to write fix patches for newly disclosed software vulnerabilities. On the 190 tasks in LiveCVEBench, VR-1.1 produced usable fixes for 57.9% of tasks, while Claude Code and Codex both scored 45.3%. The benchmark was built by Harbin Institute of Technology and Kuaishou, covers 14 programming languages, and requires patches to pass both security tests and functional tests; Cogent cut off external network access during fixing and hid the scoring tests until each agent had finished.
