Brief

AmanGotchu says that roughly three months into his tenure at SpaceXAI the team acquired Cursor, closed billion‑dollar compute agreements, released Grok Build, and delivered Grok 4.5 — a coding-and-agent-focused model trained with Cursor. Grok 4.5 is live in Grok Build, Cursor, and the API and is promoted for high speed and cost efficiency.

Why it matters

Author @AmanGotchu reports ~3 months after joining SpaceXAI the company acquired Cursor, secured billion-dollar compute deals, launched Grok Build, and shipped a coding-focused model.

Key details

  • SpaceXAI announced Grok 4.5 as their first model trained specifically for coding and agents; it was trained with Cursor and is available in Grok Build, Cursor, and the API, claiming frontier intelligence with leading speed and cost efficiency.
Source evidence

~3 months since joining, SpaceXAI has acquired Cursor, locked billion-dollar compute deals, launched Grok Build, and shipped a world-class coding model.

The trajectory here is unmatched and working on Grok Build + RL has been the most impactful work of my career.
