March 15, 2026 — Elon Musk’s artificial intelligence venture, xAI, is undergoing a foundational rebuild amid significant personnel changes and competitive pressures. Only two of the lab’s original 11 co-founders remain with the company.
Musk confirmed the restructuring on his social media platform, X. “xAI was not built right first time around, so is being rebuilt from the foundations up,” he stated. This overhaul follows the recent departure of co-founders Zihang Dai and Guodong Zhang.
Competitive Lag in Key Market
The immediate pressure stems from xAI’s performance in the AI coding tools market. Musk reportedly complained that the company’s programming assistants were not effectively competing with rival products like Claude Code from Anthropic or Codex from OpenAI.
An all-hands meeting held recently focused on strategies to catch up. Musk predicted the company could close the gap by the middle of this year. Coding tools represent a crucial revenue stream for AI labs, making xAI’s current position more than a perception issue—it’s a core business challenge.
While early user growth for xAI’s Grok model was fueled by its lax content moderation, sustainable revenue is expected to come from enterprise coding applications.
Personnel Overhaul Extends Deeper
The leadership exodus is not limited to this week. Approximately one month ago, 11 senior engineers, including two other co-founders, left xAI. Musk described those changes as a reorganization to suit a larger business structure.
According to a Financial Times report, executives from Musk’s other companies, SpaceX and Tesla, have been brought in to evaluate xAI employees and dismiss those deemed underperforming.
The two remaining original co-founders, Manuel Kroiss and Ross Nordeen, now work alongside Musk to steer the company. Musk is also personally reviewing previously rejected employment applications with colleague Baris Akis, seeking to identify promising candidates who were overlooked.
Hiring Challenges and New Talent
Industry data indicates xAI employs just over 5,000 people. This compares to more than 7,500 at OpenAI and more than 4,700 at Anthropic.
Despite the turmoil, xAI recently secured a hiring win. Andrew Milich and Jason Ginsberg joined from the AI coding tool company Cursor, where they held joint responsibility for product engineering. Their move suggests xAI’s core asset—its own frontier AI model—remains an attractive draw for talent seeking direct access to large language models and computing resources.
Broader Strategic Pressures
The pressure for results is both internal and external. xAI is now part of SpaceX, and with a potential public offering of SpaceX shares anticipated, the AI unit must demonstrate tangible progress and user adoption of Grok.
Musk’s longer-term ambition involves the “Macrohard” project, which aims to create an AI agent capable of performing any white-collar computer task. The project faced its own instability when its chosen lead, Toby Pohlen, departed within weeks of his February appointment. Reports this week indicated the Macrohard initiative was paused.
In response, Musk revealed that Macrohard is a joint effort with Tesla, which is developing a complementary agent called “Digital Optimus.” The vision involves xAI’s language model directing the Tesla agent to perform tasks. This concept parallels efforts by other companies, including Perplexity’s “Everything is Computer” offering and work underway at OpenAI.
The coming months will test whether xAI’s foundational rebuild can translate into competitive products and stable leadership as it navigates a crowded and fast-moving AI landscape.
