Grok 4 and Grok 4 Code have quietly appeared in xAI’s API infrastructure under version labels “grok-4-0629” and “grok-4-code-0629.” Grok 4 aims to deliver better natural language processing, math problem-solving, and multimodal understanding, while Grok 4 Code is designed as a code-focused companion with features tailored for integration in tools like Cursor. Musk confirmed that the official release is planned shortly after July 4, pending final validation runs. The Grok 4 architecture reportedly supports around 130,000 tokens of context and includes function calling and structured output.

This aligns with capabilities in competitive enterprise-grade LLMs like Claude and ChatGPT. The dual release positions xAI to compete simultaneously in the high-performance general AI market and the AI pair-programmer space dominated by tools like GitHub Copilot and CodeWhisperer. Grok 4 Code’s embed-in-editor support signals an emphasis on developer workflows, especially those building on Musk’s X platform or Tesla-related software stacks. If performance holds up, xAI could challenge incumbents by tightly integrating assistant capabilities across its growing ecosystem.
