Why it matters
Developers using GitHub Copilot can now leverage Google's Gemini models for enhanced code generation and assistance. This integration offers new capabilities and potentially improved performance within the Copilot ecosystem.

What changed

GitHub Copilot has integrated two new Gemini models: Gemini 3.1 Pro (Preview) and Gemini 3.5 Flash. These models are now accessible through several GitHub Copilot surfaces, including the Copilot CLI, the Copilot cloud agent, and the GitHub Copilot app (currently in technical preview). The Copilot SDK also supports these new models.

Model Availability by Subscription

  • Gemini 3.1 Pro (Preview): Available for Copilot Student, Copilot Pro, Copilot Pro+, Copilot Business, and Copilot Enterprise subscribers.
  • Gemini 3.5 Flash: Available for Copilot Pro, Copilot Pro+, Copilot Business, and Copilot Enterprise subscribers.

For organizations using Copilot Business or Enterprise, administrators must explicitly enable the relevant Gemini model policies within Copilot settings to grant users access.

Why it matters for builders

This update allows developers to utilize advanced AI models from Google directly within their GitHub Copilot workflow. The integration of Gemini 3.1 Pro and 3.5 Flash offers the potential for more sophisticated code suggestions, debugging assistance, and other AI-powered development tasks, catering to different needs based on model characteristics (e.g., performance vs. cost).

Practical impact

Developers subscribed to eligible Copilot tiers can now explore the capabilities of Gemini models within their preferred Copilot interfaces. For those using the CLI, the cloud agent, or the app, this means potentially enhanced AI assistance for coding tasks. Administrators of Copilot Business and Enterprise instances should review and enable these new model options in their settings to make them available to their teams.

Caveats and source limits

The source indicates that Gemini 3.1 Pro is in preview. The GitHub Copilot app integration is also noted as a technical preview. Specific performance benchmarks or detailed comparisons between the newly integrated Gemini models and previously available models within Copilot are not provided in the source material. The exact technical specifications and optimal use cases for each Gemini model within the Copilot context are not detailed.
