Google DeepMind Introduces CodeMender: A New AI Agent that Uses Gemini Deep Think to Automatically Patch Critical Software Vulnerabilities

Google DeepMind has developed CodeMender, an advanced AI agent capable of autonomously identifying, fixing, and upstreaming security vulnerabilities in complex software systems. Leveraging Gemini's "Deep Think" reasoning capabilities, CodeMender integrates static and dynamic analysis, fuzzing, and SMT solvers within a multi-agent framework that includes critique reviewers to ensure semantic accuracy and regression safety. Over six months of internal deployment, it successfully contributed 72 patches across open-source projects with codebases up to 4.5 million lines, demonstrating its ability to both reactively patch known issues and proactively eliminate entire classes of
