xAI announced on August 14, 2026, that Grok 4.6 is available in GitHub Copilot. The company describes Grok 4.6 as its latest coding model and presents the integration as a way for developers working in VS Code and across GitHub to access it through Copilot.
Developers can begin by opening GitHub Copilot’s model picker and selecting Grok 4.6. The announcement does not provide benchmark results or define particular development tasks supported by the model, instead directing readers to a separate Grok 4.6 announcement for more information about the model and its coding performance.
The products identified as part of GitHub Copilot include cloud agents, the Copilot command-line interface and the VS Code integrated development environment. xAI does not specify in this integration announcement whether Grok 4.6 has the same capabilities or availability conditions across each of those products.
Some business and enterprise customers will need to enable Grok 4.6 in Copilot settings before it can be selected. The notice does not identify which plans, organizations or administrative policies are covered by that requirement, so administrators may need to check their own Copilot configuration.
Grok 4.6 is also available through the xAI console. xAI lists API pricing of $2 per million input tokens and $6 per million output tokens. The announcement gives those rates for console access but does not state the pricing or subscription terms that apply when the model is used through GitHub Copilot.
Practical context: For teams already using Copilot, the integration provides a route to try Grok 4.6 within their existing development environment rather than beginning through the xAI console. Administrators may first have to enable the model, while comparisons of quality and cost with other available models remain for users to assess because this announcement includes no such comparison.
