About GitLab Duo AI
GitLab Duo is GitLab's suite of AI-powered features deeply integrated across the entire GitLab DevSecOps platform, providing code completion, chat assistance, security scanning, merge request summaries, vulnerability explanations, and pipeline failure analysis in one unified development environment. GitLab Duo Code Suggestions provides context-aware code completions and generation across 30+ programming languages directly in the IDE or GitLab's web editor. Duo Chat answers questions about code, explains merge request changes, and helps developers understand security vulnerabilities with plain-language explanations and remediation guidance. GitLab's AI security scanning automatically detects SAST, DAST, dependency, and container vulnerabilities in the CI/CD pipeline, with AI explaining each finding and suggesting fixes. For organizations with data privacy requirements, GitLab Duo can be deployed with a self-hosted AI gateway that keeps code off third-party AI services—a critical differentiator for regulated industries.
