Microsoft has opened GitHub Copilot code review in Azure Repos to all Azure DevOps customers, removing the sign-up requirement used during preview. The move gives teams that cannot yet migrate repositories to GitHub an AI reviewer inside their existing pull-request workflow.
Administrators can enable reviews at organization, project or repository level, add custom instructions and trigger automatic checks through branch policies. Each review is billed through the linked Azure subscription according to token use, review effort, pull-request size and model choice. Charges carry project tags, allowing costs to be grouped in Azure Cost Management.
There are important operational limits. Spending appears about 48 hours after a review, and Azure budgets only notify administrators; they do not stop new reviews. Microsoft caps activity at five concurrent reviews per organization, two per user and one per pull request. Self-hosted agents are unsupported, while managed pools must use a current Ubuntu Server image.
Copilot’s comments remain advisory. It never approves a pull request or requests changes, so it cannot satisfy a required-review policy or block a merge. It also does not automatically revisit new commits or respond to discussion. Teams can use it as an additional reviewer, but still need human approval and close cost monitoring when automatic policies cover busy projects.
