GitLab Duo language models

• On GitLab.com: GitLab hosts the models and connects to them through the cloud-based AI gateway.

• On GitLab Self-Managed, two options exist:

  • GitLab can host the models and the cloud-based AI gateway.
  • Your organization can use GitLab Duo Self-Hosted, which means you host the AI gateway and language models. You can use GitLab AI vendor models or the other supported language models. Watch overview
