Grok
xAI's flagship, trained on the Colossus supercluster
Grok is xAI's flagship model family, trained on the Memphis Colossus cluster and integrated natively into X and Tesla. The 2025 generations added reasoning modes and real-time X data access, and are positioned as less filtered than rivals. Grok competes at the frontier on benchmarks while leveraging X's live data.
