Why it matters
Grok 4.5 shows Musk shifting the AI fight from leaderboard claims to cost, latency and tool distribution, where a slightly weaker model can still win real usage.
Elon Musk put a ceiling and a floor on Grok 4.5 on July 8, saying his internal assessment places SpaceXAI's new model around Claude Opus 4.7, with speed and cost as the edge.

SpaceXAI launched Grok 4.5 on July 8, 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.
