GitHub Copilot Code Review Enters Public Preview for Azure Repos

Microsoft moves Copilot Code Review into public preview for Azure Repos

Microsoft announced on August 26, 2026 that GitHub Copilot Code Review for Azure Repos is in public preview, removing the earlier need to register for technical-preview access. Microsoft says the rollout is gradual and may take two to three weeks or longer to reach every Azure DevOps organization.

The feature uses GitHub Copilot as an automated pull-request reviewer. It can post comments and code suggestions, but Microsoft's documentation says Copilot leaves a comment review rather than approving a pull request or requesting changes, so it does not replace required human-review policies.

New controls for teams and administrators

The public-preview announcement adds administration at multiple scopes. Organizations can allow the feature globally, project administrators can set project defaults, and repository owners can override settings for individual repositories. Teams can also configure branch policies so a Copilot review is requested automatically when a pull request is created, including for draft pull requests.

Custom instructions can be set at organization, project, repository or path scope to steer reviews toward a team's standards. Microsoft also added support for Managed DevOps Pools. Self-hosted agent pools are not supported, and Microsoft Learn currently specifies Linux-based managed pools rather than Windows images for these review jobs.

Billing becomes easier to attribute

Copilot Code Review is billed through the Azure subscription linked to the Azure DevOps organization. Microsoft says usage is metered in GitHub AI credits, with one AI credit equal to $0.01 USD. The public-preview update adds Azure DevOps project tags to those charges so teams can group or filter costs by project and create project-scoped budget alerts.

Cost visibility does not make spend self-limiting: Azure budget alerts notify administrators when thresholds are crossed but do not automatically stop reviews.

A documentation mismatch worth noting

The August 26 announcement explicitly calls the release a public preview available to Azure DevOps customers as the rollout reaches their regions. A Microsoft Learn page last updated August 11 still labels the feature limited preview and notes staged availability. Because the announcement is newer, the public-preview status is the freshest statement, while the documentation page remains useful for current prerequisites, limits and billing details.

Two additional capabilities are still coming soon, not released today: direct links to failure logs and selectable Lite or Balanced review levels. Teams should not treat those roadmap items as currently available.
