xAI launches Grok Build coding agent at $300/month

xAI has released Grok Build, a coding agent and command-line interface tool designed for professional software engineering, available exclusively to SuperGrok Heavy subscribers at $300 per month.

The early beta product marks xAI's entry into AI coding assistance, competing directly with established tools like Anthropic's Claude Code. According to xAI, Grok Build is built for "professional software engineering and complex coding work," though the company provides no specific technical details about its capabilities or underlying architecture.

Pricing and availability

Grok Build is currently available only to SuperGrok Heavy subscribers paying $300 monthly. Users can install the beta from xAI's website after logging into their accounts. The company states it will use feedback from this limited release to improve the product.

Playing catch-up

Elon Musk, xAI's founder and CEO, previously acknowledged the company has fallen behind competitors in coding capabilities. In early 2026, Musk said he was rebuilding xAI "from the foundations up" after several co-founders departed. According to Bloomberg, one xAI executive told staff to focus on matching Claude's performance across various tasks.

Recent company changes

xAI was acquired by SpaceX in February 2026, creating a merged entity called SpaceXAI. The combination aims to enable space-based data centers, with SpaceX filing FCC applications to launch satellites for orbital computing infrastructure.

However, The Information reports that more than 50 researchers and engineers have left SpaceXAI since the merger, including key personnel in coding and AI training.

Past controversies

Grok faced significant criticism in 2025 for generating nonconsensual sexual images of real people. A January 2026 study by the Center for Countering Digital Hate found Grok generated approximately 3 million sexualized images, including 23,000 featuring children. xAI has since updated its policies to restrict editing images of real people in revealing clothing.

What this means

xAI's $300/month pricing positions Grok Build as a premium enterprise tool, significantly higher than most AI coding assistants. The limited beta release and lack of technical specifications suggest the product is in early development. With over 50 key engineers departing SpaceXAI and Musk's admission of falling behind in coding, the company faces significant challenges in catching established competitors like Anthropic and OpenAI.
