xAI's Grok 4.5 Rolls Out to GitHub Copilot
Key Takeaways
- ▸Grok 4.5 is now available in GitHub Copilot across Pro, Pro+, Max, Business, and Enterprise tiers with gradual rollout
- ▸The model features a 500,000-token context window, multimodal support (text and image), and three reasoning effort levels
- ▸Internal testing shows strong performance on terminal-based coding and parallel tool execution, ideal for agentic workflows
Summary
Grok 4.5, xAI's latest reasoning model, is now rolling out to GitHub Copilot across multiple plan tiers. The model features a 500,000-token context window, supports text and image inputs, and offers three levels of reasoning effort (low, medium, high) for different use cases.
According to internal testing by xAI and GitHub, Grok 4.5 excels at terminal-based coding tasks, parallel tool dispatch, and complex multi-step workflows, making it particularly suited for agentic coding and time-sensitive development work. The model is available to Copilot Pro, Pro+, Max, Business, and Enterprise subscribers, with gradual rollout beginning immediately.
For enterprise customers, Copilot Business and Enterprise administrators must explicitly enable Grok 4.5 via policy settings, which are disabled by default. Billing follows GitHub Copilot's standard usage-based pricing model, with rates aligned to provider list pricing.
- Enterprise administrators must manually enable Grok 4.5 via policy settings; rollout is gradual across all users
