Overview
- On Thursday, June 18, 2026, Yann LeCun said he considers Elon Musk’s xAI a "failure" and said he does not expect it to compete with frontier labs because the founding team has left and hiring top AI talent is now difficult.
- Reporting shows xAI’s founding cohort has fractured, with Business Insider saying the last non‑Musk cofounder, Ross Nordeen, was abruptly cut off from company systems as he exited.
- News outlets note SpaceX’s AI unit, which now includes xAI, reported roughly $2.5 billion in operating losses for the quarter ended March 31, underscoring heavy short‑term spending on compute and research.
- LeCun and other coverage say xAI has rented out capacity in its Colossus data centers in Memphis to firms including Google and Anthropic as a way to recoup build‑out costs, and SpaceX and xAI did not respond to requests for comment.
- LeCun warned that running large language models is costly compared with what users will pay, argued for 'world models' as a more efficient long‑term approach, and said labs may need to raise prices or cut costs or face a market correction that could prompt layoffs and consolidation.
