This story is available exclusively to Business Insider subscribers. XAI's data annotation team has faced sweeping layoffs and leadership changes this month — and the job of heading up the team training Grok has fallen to a college student who started working at the company eight months ago. On September 15, Pasini led an all-hands meeting with the team's remaining workers and said the company had no plans for further layoffs, three workers told Business Insider. Pasini joined xAI in January, according to his LinkedIn profile, after he won an xAI Hackathon in San Francisco. Pasini's youth and short tenure at Musk's companies stand in contrast to the previous leader of the data annotation team.
