Copilot code review can now be requested through the API
REST and GraphQL requests can set the effort level, and Balanced is now the default.
You can now request a GitHub Copilot code review through the REST and GraphQL APIs, and set the review effort level for each request.
Balanced is also now the default review effort level. That change took effect on September 28, 2026, a few days before the API support was announced.
Both changes are generally available on the Copilot Pro, Pro+, Max, Business and Enterprise plans.
The changelog entry does not name the new endpoints or GraphQL mutations, and it does not list the other effort levels or say how they differ from Balanced. Check the REST and GraphQL reference documentation before wiring review requests into a pipeline.
