Starting June 1, 2026, GitHub Copilot's code review feature will cost you twice due to the platform's shift to usage-based billing. Every code review on a private repository will consume both AI Credits under GitHub's new usage-based billing model and GitHub Actions minutes from your existing plan.
The reason is architectural. Copilot's code review agent runs on GitHub Actions using GitHub-hosted runners, pulling in broader repository context to produce its feedback. That compute wasn't free before. GitHub was absorbing the cost. Now they're passing it through.
When GitHub launched Copilot code review, the pitch was simple: AI-powered reviews without thinking about infrastructure. Now teams need to monitor two separate consumption metrics and manage budgets for both. Public repositories are exempt, since Actions minutes stay free for them. But for private repos on Copilot Pro, Business, or Enterprise plans, expect your Actions bill to climb.
The dual-billing model contrasts with how competitors price their AI tools. GitLab Duo and JetBrains AI both use flat-rate, per-seat subscriptions that bake infrastructure costs into the fee. Tools like CodeRabbit and Continue.dev take a different approach, letting you bring your own API keys to avoid vendor markups. Local model runners like Ollama offer a fixed-cost alternative with privacy benefits on top. GitHub is betting that the quality of its agentic reviews justifies the extra accounting work.
GitHub recommends reviewing your current Actions usage, checking spending limits, and monitoring the Billing Usage Report before June 1.
