## Summary

- SpaceXAI is launching Grok 4.5 on July 8 as its strongest model yet, its first major release since going public and acquiring Cursor.
- The pitch is enterprise work, not casual chat: Grok 4.5 is available in Grok Build, in Cursor across all plans, and through the SpaceXAI console.
- Musk frames it as an Opus-class model that is faster, more token-efficient and cheaper. Pricing is $2 per million input tokens and $6 per million output tokens.
- The launch chart claims wins over Opus 4.8, but Axios notes Grok 4.5 does not yet beat the largest latest OpenAI and Anthropic models. It is not available in the EU yet.

## Nauti's Take

SpaceXAI is selling Grok 4.5 as a practical engineering tool, then wrapping it in the usual Musk language about truth, speed and leaderboard position. The real test is not whether a launch chart beats Opus 4.8, but whether Cursor users get fewer broken diffs, less context loss and lower bills. The missing EU availability is a real constraint for European teams. Test it, but do not migrate on PR benchmarks alone.
