Copilot Code Review: Effort Levels Reach General Availability

GitHub CopilotView original changelog

GitHub Copilot code review now offers two general-availability effort levels — Lite and Balanced — replacing the preview-era "Low" and "Medium" naming. Lite stays fast and cost-efficient for straightforward changes, while Balanced routes pull requests to a higher-reasoning model for deeper analysis of complex logic and security-sensitive code. Organizations can set an org-wide default that repositories inherit, and the effort level used is now surfaced directly in timeline events and PR overview comments. The capability is available across Copilot Pro, Pro+, Max, Business, and Enterprise plans.

Key Takeaways

  • GitHub Copilot code review's effort-level controls are now generally available, moving out of the public preview that used the "Low/Medium" naming.
  • The two tiers were renamed to Lite and Balanced to better communicate the trade-off between speed and depth.
  • Balanced reviews route pull requests to a higher-reasoning model for complex logic and security-sensitive changes, at the cost of more AI credits and Actions minutes.
  • Organizations can set an org-wide default effort level that individual repositories inherit but can override.
  • The effort level used for a given review is now visible in PR timeline events and overview comments, adding transparency to automated reviews.
  • Existing preview configurations were automatically migrated to the new naming with no manual work required from teams.

Copilot Code Review Effort Levels Graduate to General Availability

GitHub has moved its Copilot code review effort-level controls out of public preview and into general availability, giving every paid Copilot plan a way to tune how deeply an automated review digs into a pull request. The capability first appeared in preview as "Low" and "Medium" review depth; with general availability, GitHub renamed the two tiers to Lite and Balanced to better describe what each one does.

Two Levels, Two Trade-Offs

Lite is the default and remains the fast, cost-efficient option, tuned for straightforward changes such as documentation edits, small refactors, and low-risk pull requests. It targets common issues — bugs, security vulnerabilities, and style inconsistencies — without routing the request to a heavier reasoning model.

Balanced, by contrast, sends the pull request to a higher-reasoning model built for deeper analysis. It's designed for complex logic, security-sensitive code paths, and changes that span multiple services, where a more thorough pass is worth the extra AI credits and compute time. GitHub Copilot flags that Balanced reviews consume more AI credits and GitHub Actions minutes than Lite reviews, so teams can weigh cost against review depth on a per-repository or per-pull-request basis.

Organization-Wide Defaults with Local Overrides

Administrators can set a default effort level for their entire organization from Organization → Copilot → Copilot code review in settings. Individual repositories automatically inherit that default but can override it locally, giving teams flexibility to apply a stricter Balanced review to security-critical repositories while keeping lower-stakes projects on Lite.

Transparency Built Into the Review

To help teams track review depth across their codebase, GitHub Copilot now surfaces which effort level generated a given review in two places: the pull request's timeline events and the Copilot-generated overview comment on the PR itself. This makes it easy for a reviewer or team lead to glance at a PR and confirm whether it received a fast Lite pass or a deeper Balanced analysis, without digging through settings.

Smooth Migration From Preview

Teams that had already configured the Low/Medium preview settings do not need to take any action — GitHub automatically transitioned existing configurations to the new Lite/Balanced naming scheme, preserving whatever defaults were already in place.

Availability

Both effort levels are available now to Copilot Pro, Pro+, Max, Business, and Enterprise subscribers, making this one of the broader-reaching updates to Copilot code review since it reached general availability.
