‘Not built right the first time’ — Musk’s xAI is starting over again, again

Elon Musk’s artificial intelligence lab, xAI, is undergoing a foundational overhaul, with only two of the original 11 co-founders remaining as the company struggles to keep pace with competitors. Musk admitted the company “was not built right first time around” and is being rebuilt amid intense pressure. The most recent departures, co-founders Zihang Dai and Guodong Zhang, followed Musk’s complaints that xAI’s AI coding assistants were failing to effectively compete with Anthropic’s Claude Code and OpenAI’s Codex, highlighting a critical business vulnerability for the lab.

The internal turmoil extends beyond the founding team. A month ago, 11 senior engineers left following a reorganization, an effort that was apparently insufficient as executives from SpaceX and Tesla were brought in to evaluate and dismiss underperforming staff. The pressure to deliver commercially viable products, particularly in the lucrative coding tools market, is immense. This operational crisis has also stalled strategic projects, with the “Macrohard” initiative—aimed at creating a white-collar work agent—reportedly paused after its leader departed within weeks. Musk has since reframed the project as a joint effort with Tesla, envisioning xAI’s language model directing a complementary Tesla agent dubbed “Digital Optimus.”

Despite the internal chaos, xAI's core technology remains a powerful draw for talent, evidenced by its recent hiring of Andrew Milich and Jason Ginsberg from the AI coding tool company Cursor. Their move suggests direct access to a frontier model and its associated compute resources is a significant advantage. Still, the pressure to show results is mounting externally. As a unit of SpaceX, which is anticipating a public offering, xAI must demonstrate tangible progress and user adoption for its Grok LLM to satisfy future investors. The company's vision for an all-purpose agent now competes directly with similar ambitious projects from rivals like Perplexity and OpenAI, making this rebuild a high-stakes race against a rapidly advancing market.

While Musk’s willingness to tear down and rebuild is characteristic, doing so in the hyper-competitive, capital-intensive frontier AI space is a significant gamble. The ongoing talent exodus and reliance on his other companies for executive oversight suggest xAI’s foundational issues are more operational than technical, creating an urgent need to stabilize its structure before it can hope to close the gap with its rivals.
