GitLab Duo

GitLab Duo is a comprehensive suite of AI-powered capabilities integrated natively into the GitLab DevSecOps platform. Built on an AI abstraction layer, it utilizes a multi-model approach (leveraging Anthropic, Google Vertex AI, and specialized local models) to assist teams throughout the planning, coding, security, and monitoring phases. Unlike standalone coding assistants, Duo provides context from the entire DevSecOps lifecycle, including issue tracking, merge requests, and security vulnerabilities. As of 2026, its market position is solidified by its 'Privacy-First' approach, ensuring that customer code is never used to train foundational models—a critical requirement for enterprise and government sectors. The platform offers two primary tiers: Duo Pro for individual developer productivity and Duo Enterprise for organizational-wide governance, security resolution, and advanced CI/CD root cause analysis. Its architecture supports cloud-connected, air-gapped, and GitLab Dedicated environments, making it a leader in the Sovereign AI movement within software engineering.
