xAI, led by Elon Musk, has launched the Grok 4 and Grok 4 Heavy AI models, claiming significant advantages over the coding tool Cursor. Musk emphasized Grok 4's ability to automatically fix entire source code files, asserting, "Works better than Cursor." Notably, Grok 4 also leads key reasoning benchmarks. As Cursor users express dissatisfaction with recent changes to pricing plans, xAI remains positioned to capitalize on dissatisfaction in the coding tool market.
