Grok 4.6 launches on Cursor; lands in GitHub Copilot two days later
SpaceXAI
SpaceXAI released Grok 4.6 on August 12, 2026, co-announced with Cursor; Cursor framed it as a frontier model for long-running agents and ambitious interactive / visual work at $2/M input and $6/M output ($4/$12 for a fast variant), with 2x included usage in Cursor and Grok Build for the first week. On August 14 Grok 4.6 also went live in GitHub Copilot at the same pricing, via the SpaceXAI API and partners OpenRouter, Vercel, and Cloudflare.
Why it matters
Grok 4.6 is the first model released as part of the SpaceX-Cursor relationship and immediately became available in two of the highest-traffic coding surfaces (Cursor and Copilot) with a coordinated promo window in Cursor Build.
Importance: 4/5
