Grok Code Fast 1 Now Rolling Out for GitHub Copilot

GitHub is rolling out Grok Code Fast 1 as an opt-in public preview for GitHub Copilot Pro, Pro+, Business, and Enterprise plans in Visual Studio Code. The rollout is gradual, so users who don’t see it yet should check back soon.

Availability and Access

Plans Supported: Pro, Pro+, Business, and Enterprise can access Grok Code Fast 1 in Visual Studio Code.
Gradual Rollout: The new model is being released in phases, so it may not appear immediately for everyone.

xAI Model Access with BYOK

Individual Plans: xAI models, including Grok Code Fast 1, are available to Copilot individual plan users via Bring Your Own Key (BYOK). This requires providing your own xAI API key.

For Individual Paid Plans: Simply choose Grok Code Fast 1 from the model picker in Visual Studio Code and complete the one-time prompt.
BYOK Access: Select Manage Models in the Visual Studio Code model picker, choose xAI, enter your API key, and then select Grok Code Fast 1.
