Summary
On August 14, 2026, Grok 4.6 became selectable in GitHub Copilot's model picker across eight surfaces (VS Code, Visual Studio, the Copilot CLI, the Copilot cloud agent, the Copilot app, JetBrains IDEs, Xcode, and Eclipse), two days after xAI released the model. It is available on Copilot Pro, Pro+, Max, Business, and Enterprise plans, billed at $2 per million input and $6 per million output tokens, with enterprise admins able to enable it in settings.
What changed
GitHub added xAI's Grok 4.6 to the Copilot model picker across eight editors and agent surfaces, on paid Copilot tiers, at $2/$6 per million input/output tokens.
Why it matters
Copilot's multi-model marketplace keeps widening: putting Grok 4.6 next to models from OpenAI, Anthropic, and Google inside Copilot turns model choice into a per-task decision for millions of developers and gives xAI immediate distribution into enterprise coding workflows.
