> xAI put Grok 4.5 in GitHub Copilot across VS Code, Copilot CLI, and cloud agents—selectable from the model picker (enterprise enablement may be required). API at $2/$6 per MTok. Copilot availability changes where developers invoke the model, not Arena or AA ranks by itself.

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 xAI against OpenAI-default Copilot habits—and expands Grok beyond grok.com / X. It does **not** by itself change Arena or Artificial Analysis ranks.

**xAI** 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 **xAI 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](https://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. Copilot remains multi-vendor; Grok joins OpenAI, Anthropic, Google, and other models already offered depending on plan.

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.

## Limits

- Enterprise enablement rates and default picker choices are unmeasured here.
- No new independent Arena/AA snapshot is claimed for this distribution ship.
- Microsoft 365 Copilot parity is not part of this announcement.
