xAI Launches Grok Build Coding Agent in Early Beta for SuperGrok Heavy Subscribers
xAI has officially introduced Grok Build, a new coding agent and command-line interface designed for professional software engineering. Currently available only in an early beta version, the tool is exclusively accessible to SuperGrok Heavy subscribers, who pay $300 monthly for the service. This launch represents xAI's strategic effort to compete with rival products like Anthropic's Claude Code, addressing CEO Elon Musk's admission that the company previously lagged in coding capabilities. The release follows significant internal restructuring, including a merger with SpaceX in February 2026, which aims to leverage space-based data centers for AI processing. However, the combined entity, reportedly named SpaceXAI, has faced challenges, including the departure of over 50 researchers and engineers. Additionally, xAI continues to manage reputational risks following previous controversies involving Grok generating nonconsensual sexualized images. The company intends to use feedback from this limited beta release to refine Grok Build's performance and safety measures before a wider rollout.
