GitLab Duo

GitLab Duo is a suite of AI-powered features that assist you while you work in GitLab. These features aim to help increase velocity and solve key pain points across the software development lifecycle.

GitLab Duo features are available in IDE extensions and the GitLab UI. Some features are also available as part of GitLab Duo Chat.

GitLab is transparent. As GitLab Duo features mature, the documentation will be updated to clearly state how and where you can access these features.

Generally available features

GitLab Duo Chat

• Help you write and understand code faster, get up to speed on the status of projects, and quickly learn about GitLab by answering your questions in a chat window.
• LLMs: Anthropic Claude 3.5 Sonnet, Anthropic Claude 3 Haiku, and Vertex AI Search. The LLM depends on the question asked. For more information, see the Duo Chat examples. For self-managed, the models also depend on your GitLab version. For the most benefit, use the latest GitLab version whenever possible.

Self-Hosted Models

Use your own language models to power AI features in GitLab. Code Suggestions and Duo Chat are supported.

You can use language model vendors provided by GitLab or fully manage language models in your self-hosted environment.

• Use GitLab model vendors: Connect with default external model providers, like Google Vertex AI or Anthropic, by using the GitLab-managed AI gateway.
• Host your own models: Deploy and manage your own AI gateway and language models in your infrastructure, without depending on GitLab-provided external language providers.
