GitLab Duo Code Suggestions · San Francisco, California, United States · founded 2011
What it is
GitLab Duo Code Suggestions completes and generates code in supported editors. It can fill in code blocks, help define function logic, generate tests, and suggest common code such as regular-expression patterns. Supported environments include Visual Studio Code, GitLab Web IDE, Visual Studio 2022 for Windows, JetBrains IDEs, Neovim, and Eclipse; GitLab lists more than 14 supported languages, including C++, C#, Go, Java, JavaScript, Python, Rust, and TypeScript. Code Suggestions is available on the GitLab.com Free tier with GitLab Credits and for self-managed GitLab instances through a secure connection to GitLab.com. GitLab says private, non-public customer code stored in GitLab is not used to train its generative AI models. It also says suggestions are scanned to help guard against sharing sensitive information such as passwords or API keys. For Fireworks AI requests, inputs and outputs are discarded after a result is returned, except when prompt caching is enabled. GitLab warns that heavy demand can affect performance or cause unexpected downtime.
