Two unreleased Grok models, named Grok 4 and Grok 4 Code, have been spotted in the source code of xAI’s developer console. It was first spotted by the X account named AiBattle, which is known for digging into the backend updates of major AI platforms.
According to the leaked descriptions, Grok 4 is being positioned as xAI’s “latest and greatest flagship model,” built to deliver top-tier performance across natural language processing, mathematics, and reasoning tasks. Meanwhile, Grok 4 Code is designed specifically as a coding assistant that can integrate directly into code editors, potentially aiming to compete with tools like GitHub Copilot and Cursor.
