SpaceXAI launched Grok 4.5 on July 8th, pitching it more for coding, agentic tasks, and knowledge work than consumer chat. According to Axios, Grok 4.5 is available in Grok Build, in Cursor on all plans, and via the SpaceXAI console, but it is not yet available in the EU. Axios also reports pricing at $2 per million input tokens and $6 per million output tokens.
