xAI officially launched the early beta of Grok Build, a coding agent designed for professional software engineering, on May 25, 2026. [1, 2] The service is initially available only to SuperGrok Heavy subscribers, who pay $300 per month. [2] These users can install and access Grok Build directly from xAI’s website after logging in.

xAI describes Grok Build as a powerful command line interface tool tailored for complex coding tasks and professional developers. [2] The launch marks the first public release of Grok Build since SpaceX acquired xAI in February 2026. [2]
Since the merger, more than 50 engineers and AI researchers have departed from SpaceXAI, including key staff involved in coding and AI training. [2] Despite this turnover, xAI continued development of Grok Build under SpaceX ownership. [2]
Earlier in 2026, a study by the Center for Countering Digital Hate revealed Grok AI had generated up to 3 million nonconsensual sexualized images, including 23,000 featuring children. [2] In response, xAI revised Grok’s policies to block editing images of real people in revealing clothing. [2]
SpaceX has filed applications with the FCC to launch satellites to create an orbital data center supporting xAI, which may boost capabilities for Grok Build and other AI services. [2]
SuperGrok Heavy subscribers remain the sole users currently able to access the Grok Build early beta. The subscription fee for this tier remains $300 monthly. [2]
The next key step will be monitoring user feedback and adoption among SuperGrok Heavy members, as xAI expands Grok Build beyond beta and adjusts features based on professional user needs. [1, 2]
