GitLab Duo Chat, a new feature in GitLab Duo Enterprise, streamlines merge request (MR) reviews. It allows users to ask questions about the MR directly within GitLab, receiving answers instantly. The AI assistant understands the MR's context, including code changes, discussions, and metadata. This accelerates onboarding and allows for in-depth conversations about the changes. Users can inquire about design choices, potential risks, and implementation details. GitLab Duo Chat goes beyond summarizing code; it facilitates understanding the reasoning behind modifications. It supports follow-up questions for deeper exploration of the MR's complexities. The tool is constantly evolving to become a more effective conversational partner. Feedback from users is crucial for its continued improvement. A free trial of GitLab Ultimate and GitLab Duo Enterprise is available to explore this feature.
