GitHub's Copilot CLI now allows users to bring their own AI model or run models locally. However, relying solely on model selection is insufficient for enterprise-level automation where governance is crucial. GitLab Duo CLI, built on the Duo Agent Platform, offers a different approach, focusing on enterprise-grade control across the software delivery pipeline. Duo CLI supports both interactive development and automated workflows in CI/CD pipelines, including headless mode. This platform-level control ensures consistent governance, auditing, and security, unlike Copilot's per-developer configurations. Duo CLI offers prompt injection detection, composite identity scopes and custom instruction files (AGENTS.md and SKILL.md) to manage agent permissions. This allows teams to debug pipelines and automate complex development tasks securely. When considering AI tooling for the platform, the need for enterprise-level control and robust security in the absence of human oversight becomes critical. GitLab Duo facilitates model flexibility by supporting self-hosted and GitLab-hosted models, allowing for data sovereignty. Teams can start a free trial or sign up with their existing GitLab subscriptions to experience the benefits of GitLab Duo CLI.
