Summary

GitLab Duo Code Suggestions completes and generates code in supported editors. It can fill out code blocks, help define function logic, produce tests, and suggest common patterns such as regular expressions. Supported editors include Visual Studio Code, GitLab Web IDE, Microsoft Visual Studio 2022 for Windows, JetBrains IDEs, Neovim, and Eclipse. GitLab lists support for over 14 languages, including C++, C#, Go, Java, JavaScript, Python, Rust, and TypeScript. The feature is available on the GitLab.com Free tier with GitLab Credits and can also be used with self-managed GitLab instances through a secure connection to GitLab.com. GitLab says it does not train generative AI models and that private, non-public customer code stored in GitLab is not training data. Suggestions are scanned to help prevent sensitive details such as API keys or passwords from being shared. GitLab warns that high demand can degrade performance or lead to unexpected downtime for GitLab Duo AI features.

Verdict
