Grok
20 models · SpaceXAI
The Grok family (Grok 1 through 4.5, including Fast, mini, Code Fast, and dated 4.20 builds) from Elon Musk's xAI lineage — reasoning-strong flagships with live X/Twitter data access and a deliberately irreverent style. Grok 4 topped several reasoning benchmarks at launch; 4.x Fast tiers trade depth for speed.
