# Two xAI cofounders announce departures in quick succession

Two co-founders of Elon Musk’s xAI resigned with little explanation, leaving the AI company with half of its original dozen co-founders.

Tony Wu announced early Tuesday that he had resigned from xAI, saying it was “time for my next chapter” and thanking Musk “for believing in the mission and for the ride of a lifetime.”

“This company – and the family we became – will stay with me forever,” he wrote in a post on X. “I will deeply miss the people, the warrooms, and all those battles we have fought together.”

“It is an era with full possibilities: a small team armed with AIs can move mountains and redefine what’s possible,” Wu added. “Thank you to the entire xAI family. Onward.”

His fellow co-founder, Jimmy Ba, also turned to X late Tuesday to announce that he had marked his “last day at xAI,” noting it was “time to recalibrate my gradient on the big picture.”

“Grateful to have helped cofound at the start,” Ba said. “And enormous thanks to @elonmusk for bringing us together on this incredible journey. So proud of what the xAI team has done and will continue to stay close as a friend of the team. Thank you all for the grind together.”

Four other xAI co-founders have departed since the company launched in 2023. The latest resignations come after Musk said last week that SpaceX had acquired xAI. In his announcement, the tech billionaire focused heavily on building out AI data centers in space.

The AI company has also come under scrutiny over the past month, after its chatbot Grok produced thousands of sexualized images of women and children in response to user requests on X. The platform has since restricted image editing and generation tools but still faces several investigations.
