Gemini 3.5 Flash is generally available for GitHub Copilot

Gemini 3.5 Flash, Google’s latest Flash-tier model, is now rolling out on GitHub Copilot. In our early testing, Gemini 3.5 Flash delivers near-Pro coding quality at Flash-tier speed and cost with strong tool use, fast response times, and high cache efficiency that make it well-suited for fast, iterative agentic coding workflows.

Note, that while this model is launching with a 14X premium request multiplier, pricing is tentative and subject to change.

Availability in GitHub Copilot

Gemini 3.5 Flash will be available to Copilot Pro, Copilot Pro+, Copilot Business, and Copilot Enterprise users.

You’ll be able to select the model in:

• Visual Studio Code in versions 1.115.0 or later
• Visual Studio in versions 17.14.22 or 18.1.0 and later
• JetBrains
• Xcode
• Eclipse

Rollout will be gradual. Check back soon if you don’t see it yet.
