What is GitLab Duo?

GitLab Duo is the AI layer woven through the GitLab platform: code suggestions in your IDE, chat grounded in your project's issues and merge requests, vulnerability explanations, merge-request summaries, code-review assistance, and root-cause analysis for failing pipelines. For teams already living in GitLab, it removes the context-switching that separate AI tools usually impose on developers.

Duo's agentic features can carry out multi-step work such as fixing pipeline failures or drafting changes from an issue description. It is sold as a per-seat add-on to GitLab subscriptions, in Pro and Enterprise tiers with different capabilities; outside GitLab-centric organisations it has little reach, and some advanced agent features require the higher tier to unlock.
