PANews reported on February 27th that Toby Pohlen, co-founder of Elon Musk's artificial intelligence company xAI, announced his departure today. He stated on the social media platform X, "Today is my last day at xAI," and jokingly remarked that "no one on the team can stay up all night better than you guys," adding that he plans to "get more than eight hours of sleep first."

This marks the fourth xAI co-founder to publicly resign in the past three months. Since the company's founding in 2023, seven of the twelve founding members have confirmed their departure, including former Google scientist Tony Wu, University of Toronto professor Jimmy Ba, and Groq founding member Greg Yang.
