Igor Babuschkin announced this week that he is leaving the company he helped cofound with Elon Musk to start his own company focused on AI safety research.
Babuschkin posted the news on X, which is owned by xAI, Elon Musk’s artificial intelligence company.
“Today was my last day at xAI, the company that I helped start with Elon Musk in 2023,” he wrote. “I still remember the day I first met Elon. We talked for hours about AI and what the future might hold.”

Babuschkin wrote that “through blood, sweat, and tears,” they “shipped frontier models faster than any company in history,” and during the process, he earned two “priceless” lessons from Musk.
1. Be fearless
“Be fearless in rolling up your sleeves to personally dig into technical problems,” he wrote. Babuschkin noted that Musk personally worked with the team, flying to a data center and staying all night until the issues were fixed.
2. Have a “maniacal” sense of urgency
“xAI executes at ludicrous speed,” he wrote. “Industry veterans told us that building the Memphis supercluster in 120 days would be impossible. But we believed we could do the impossible.”
Today was my last day at xAI, the company that I helped start with Elon Musk in 2023. I still remember the day I first met Elon, we talked for hours about AI and what the future might hold. We both felt that a new AI company with a different kind of mission was needed.

Musk replied to his post, offering thanks: “Thanks for helping build xAI! We wouldn’t be here without you.”
