Grok 4.6 Lands in GitHub Copilot Two Days After Launch
On August 14, 2026, SpaceXAI said Grok 4.6 is live in GitHub Copilot across VS Code, cloud agents, and the Copilot CLI, with some businesses needing to enable the model in Copilot settings; API pricing remains $2/$6 per million tokens.
TLDR
SpaceXAI on August 14, 2026 posted that Grok 4.6 is now live in GitHub Copilot for developers in VS Code and across GitHub, including cloud agents and the Copilot CLI. Users pick “Grok 4.6” in the model picker; some businesses and enterprises must enable it in Copilot settings. The same post restates SpaceXAI console pricing: $2 / $6 per million input/output tokens. This is a distribution ship—two days after the August 12 model GA—not a second model launch.
What shipped
| Item | Detail (x.ai/news/grok-4-6-github-copilot) |
|---|---|
| Date | August 14, 2026 |
| Surfaces | GitHub Copilot in VS Code, cloud agents, Copilot CLI |
| Enablement | Model picker; some biz/enterprise tenants need an admin flag |
| API | SpaceXAI console still $2 / $6 per 1M |
Same pattern as Grok 4.5 (Jul 8 launch) then Grok 4.5 in GitHub Copilot (Jul 28): model first, Copilot second, separate slugs.
Why this story matters
Copilot is still the default editor agent for a large share of professional developers. Putting Grok 4.6—the checkpoint SpaceXAI says ties GPT-5.6 Sol at 61 on Artificial Analysis—next to OpenAI and Anthropic in that picker is the distribution that actually moves coding tokens. Watch: default vs opt-in inside enterprise tenants, and whether Microsoft prices Grok as a premium Copilot model.
