GitHub Copilot adds Google's Gemini 4 Hydrogen model across IDEs and apps

GitHub, a Microsoft company, announced on November 13, 2026, that Google's Gemini 4 Hydrogen model is now available inside GitHub Copilot, according to the GitHub Changelog post on Gemini 4 Hydrogen.

What changed

• Gemini 4 Hydrogen became available in GitHub Copilot on November 13, 2026, positioned for fast, efficient agentic coding, tool use, and multistep workflows.
• GitHub says the model shows improved instruction-following compared to Gemini 3.8 Flash.
• The model is available to Copilot Pro, Pro+, Max, Business, and Enterprise plan subscribers.
• Rollout spans VS Code, Visual Studio, Copilot CLI, the Copilot coding agent, the Copilot app, github.com, GitHub Mobile on iOS and Android, JetBrains IDEs, Xcode, and Eclipse.
• The rollout counts as general availability but is gradual rather than instant for every user.

What it means for people building with AI

Adding Gemini 4 Hydrogen gives Copilot's developer base a faster, more efficient model option right after Google shipped it, intensifying model-choice competition inside the most widely used AI coding assistant. Builders who rely on agentic workflows, tool use, and multistep tasks gain another option to weigh for speed and cost alongside Copilot's existing models.

Billing and access controls

• Model usage is billed at provider list pricing under Copilot's usage-based billing.
• Business and Enterprise admins can control access to Gemini 4 Hydrogen through model policy settings, where new models default to enabled.
