GitHub Copilot adds Gemini 3.6 Flash
The practical shift is not model bragging. It is that Copilot users now get another current model option inside the place coding work already happens.
GitHub says Gemini 3.6 Flash, Google’s latest Flash model, is rolling out in GitHub Copilot. The summary says it is designed for web and app development, coding, and longer-horizon agentic tasks, with configurable settings. Treat this as a useful model-choice moment: the same coding task can now be compared inside the GitHub workflow instead of moved between separate tools. For daily shipping, the action is simple: pick one real app task, run it through the usual coding agent path and through Copilot with Gemini 3.6 Flash, then compare correctness, patch size, and review burden. Verdict: test, not switch by default.
