Elon Musk admits falling behind, xAI launches its first programming agent, targeting industry leader Claude Code

Elon Musk’s xAI is striving to catch up with competitors in the programming AI race, but internal talent loss continues to plague this startup.

On Thursday, May 14th, xAI released its first AI programming agent Grok Build, challenging Anthropic’s Claude. The product is currently in early testing phase, available only to paid subscription users.

xAI President Michael Nicolls has explicitly set “achieving Claude’s task performance level” as a recent company goal.

Programming is one of the most promising sub-sectors for AI commercialization. Elon Musk himself admits that xAI has fallen behind competitors in this field. The launch of Grok Build marks the company’s official entry into the professional programming market.

Product Positioning: Terminal programming tool for professional developers

Grok Build is delivered in a command-line interface (CLI) format, running directly on the user’s terminal, initially open only to SuperGrok Heavy subscribers.

According to xAI’s official website, this agent can perform complex programming tasks based on user instructions, supporting a “planning mode” — users can review, comment, or even rewrite task plans before execution, with all code changes shown as diffs for easy tracking by developers.

Another core feature of the product is the parallel sub-agent mechanism: for larger-scale tasks, Grok Build can split work and delegate to multiple specialized sub-agents executing simultaneously, and it supports deep code repository integration (worktree integration).

Additionally, this tool is compatible with existing AGENTS.md configurations, plugins, hooks, and MCP servers, reducing developers’ migration costs.

xAI states that, with headless mode support, agents can be embedded into scripts and automation workflows, providing full support for the ACP protocol, enabling developers to build custom bots and orchestrate intelligent agent applications.

Programming AI Race Heats Up

AI programming is currently recognized as a high-value market across the entire artificial intelligence industry, with Anthropic’s Claude widely regarded as the industry benchmark in this niche.

xAI’s entry will further intensify competition in this sector. However, Grok Build is still in early testing, and its actual performance and stability remain to be validated by the market.

xAI says it will continuously iterate the product based on user feedback and has opened a /feedback command within the CLI for users to submit suggestions directly to the team.

For investors, whether xAI can truly compete positively with Claude under the dual pressures of talent turbulence and rapid product iteration will be a key variable in observing the company’s development trajectory.

Chasing Competitors, Internal Rebuilding in Progress

xAI’s move into the AI programming race is part of a broader company restructuring plan.

Elon Musk is reshaping xAI’s image and strength in preparation for the upcoming IPO of its parent company SpaceX. The restructuring involves layoffs, signing new cooperation agreements, and large-scale recruitment to fill the vacancies left by founding members’ departures.

On the collaboration front, last month, xAI signed an agreement with AI programming tool company Cursor, covering programming capabilities collaboration and shared computing resources. According to Bloomberg, informed sources say Cursor engineers have recently begun collaborating with the xAI team.

However, the pressure of talent loss has not eased.

According to Bloomberg, several core engineers recently left xAI’s Palo Alto office, including Devendra Chaplot, co-founder of Mistral AI who joined in March this year, and Beibin Li, responsible for leading the post-training team.
