Grok 4.6 lands in GitHub Copilot across every IDE it runs in
xAI's reasoning model is now a menu pick from Pro to Enterprise, billed at xAI's own list rate — the second frontier model Copilot added this week.

Every IDE, but off by default for teams
Grok 4.6 reaches Copilot Pro, Pro+, Max, Business, and Enterprise across VS Code, Visual Studio, JetBrains, Xcode, Eclipse, the CLI, the cloud agent, and the Copilot app. Business and Enterprise admins have to flip the Grok 4.6 policy on first — it ships disabled.
Billed at xAI's meter, no flat multiplier
Copilot charges it at provider list pricing under usage-based billing, with no premium-request multiplier quoted — so cost tracks xAI's own rate, reported at $2 per million input tokens and $6 output when Grok 4.6 shipped Aug 12. Price your agent loops before pointing them at it.
Gemini 3.7 Flash joined the picker a day earlier
Copilot added Google's Gemini 3.7 Flash on Aug 13 — the cheap coding-and-agents workhorse now sits in the same model menu. Two frontier options in two days means more you can route to without leaving the editor.
Elsewhere: Cursor's cloud agents boot 3x faster
Cursor shipped 'Builds': cloud agents now start in a pre-warmed environment instead of rebuilding each run, cutting time-to-first-token ~3x (internal boot 10x) with a new Builds tab for logs and commit SHAs. Free for Cloud Agents users.
