Grok 4.5 Lands in GitHub Copilot
On July 28, 2026, SpaceXAI announced that Grok 4.5—its flagship coding model—is available in GitHub Copilot across cloud agents, Copilot CLI, and VS Code, selectable from the model picker (enterprise enablement required for some orgs), with API pricing at $2/$6 per million input/output tokens.
TLDR
SpaceXAI on July 28, 2026 announced that Grok 4.5 is available in GitHub Copilot. Developers can select “Grok 4.5” from the Copilot model picker in VS Code, the Copilot CLI, and cloud agents. Some business/enterprise tenants must enable the model in Copilot settings. On the SpaceXAI API, Grok 4.5 is listed at $2 per million input and $6 per million output tokens.
Distribution details
| Surface | Access |
|---|---|
| GitHub Copilot (IDE) | Model picker → Grok 4.5 |
| Copilot CLI / cloud agents | Same model family where Copilot multi-model is offered |
| Enterprise | Admin enablement may be required |
| Direct API | console.x.ai — $2 / $6 per MTok in/out |
This is a distribution GTM story on top of the earlier Grok 4.5 model launch (filed mid-July under SpaceXAI’s product calendar). Copilot remains multi-vendor; Grok joins OpenAI, Anthropic, Google, and other models already offered depending on plan.
Independent ranking context (model, not Copilot-specific)
Grok 4.5’s standing remains as previously covered for the model launch: competitive coding/agent scores with price leverage versus Sol/Fable-class proprietary peers. Copilot availability does not by itself change Arena or Artificial Analysis ranks—it changes where developers can invoke the model without leaving GitHub’s stack.
Why this story matters
Copilot is still the default IDE AI for a large share of professional developers. Adding Grok 4.5 as a first-class picker option is a channel win for SpaceXAI against OpenAI-default Copilot habits and expands Grok beyond grok.com / X. Watch enterprise enablement rates, default model choices in VS Code, and whether Microsoft surfaces Grok in Microsoft 365 Copilot similarly.
