Exclusive: Cogent Security’s VR-1.1 model outscores Claude Code and Codex on vulnerability repair

Vulnerability management startup Cogent Security Inc. today released VR-1.1, a new version of its frontier reasoning model that writes fixes for newly disclosed software vulnerabilities. On a public repair benchmark, the model outscored Anthropic PBC’s Claude Code and OpenAI Group PBC’s Codex. The release goes after the part of vulnerability management that has not sped up. In July, research group Epoch Artificial Intelligence Inc. counted about 2,500 high- and critical-severity disclosures from major organizations, roughly five times the monthly record set before Anthropic announced Claude Mythos Preview in April. Each repair still needs an engineer who understands the flaw well enough to change the code without breaking something else.
