xAI Loses Half of Founding Team as IPO Looms; Key Researchers Leave Amid Grok Controversies

xAI, preparing for an upcoming IPO, is losing half of its founding team as key researchers depart amid heightened scrutiny and competition. In a深夜 post on X, Yuhuai Wu, one of the co-founders, announced his resignation, noting the era of "a small team equipped with AI can move mountains" is upon him. Of the 12-person founding team, five have left in the past 18 months, including Kyle Kosic joining OpenAI, Christian Szegedy leaving for Google, Igor Babushkin founding a venture firm, and Greg Yang departing on health grounds. While departures appear voluntary, with SpaceX’s acquisition complete and an IPO on the horizon offering significant financial upside, internal tensions are rising. Concerns include erratic behavior and疑似 internal tampering with Grok, the company’s flagship chat model, and recent changes to its image generation tools that have fueled a surge in deepfake pornography, prompting legal actions. With the IPO approaching and pressure to outpace Anthropic, retention of core AI talent is critical to the company’s success.
