Summary
On July 8, 2026 Cursor made SpaceXAI's Grok 4.5 — a model trained alongside Cursor for coding, agentic, and knowledge work — selectable on all Cursor plans across desktop, web, iOS, CLI, and the SDK, the same day SpaceXAI launched it publicly. Grok 4.5 is not yet available in the EU.
What changed
Cursor added Grok 4.5 on July 8, 2026 across desktop, web, iOS, CLI, and its SDK on all plans, coinciding with SpaceXAI's public launch. SpaceXAI positions Grok 4.5 as its strongest model, trained alongside Cursor for coding and long-running agentic tasks; EU availability is pending.
Why it matters
Grok 4.5 was trained alongside Cursor, so day-one availability across every Cursor surface turns a model launch into a distribution advantage for both companies and deepens a data-and-model flywheel between an AI lab and a coding tool. For developers it adds an Opus-class option at lower coding-agent pricing directly in the editor, sharpening model choice inside Cursor.
Evidence excerpt
Grok 4.5 is available today in Cursor across desktop, web, iOS, CLI, and our SDK. Grok 4.5 is not yet available in the EU in any SpaceXAI products or the API console.
