At least nine engineers, including two co-founders<\/a>, have now publicly announced their departure from xAI in the past week \u2013 though two of those exits appear to have occurred a few weeks ago.\u00a0<\/p>\n Neither xAI nor Elon Musk have publicly commented on the departures.\u00a0<\/p>\n While attrition is typical at startups, co-founder departures are far less so. More than half of xAI\u2019s founding team has now left, and the fact that several employees followed within days has intensified scrutiny around the company\u2019s stability.<\/p>\n Three of the departing staff members say they will be starting something new alongside other former xAI engineers, although no details are available about the new venture. Others hint at a desire for more autonomy and smaller teams to build frontier tech more rapidly, pointing to the anticipated surge in AI productivity.<\/p>\n Yuhai (Tony) Wu, an xAI co-founder and reasoning lead, said in a post<\/a> announcing his resignation: \u201cIt\u2019s time for my next chapter. It is an era with full possibilities: a small team armed with AIs can move mountains and redefine what\u2019s possible.\u201d<\/p>\n Shayan Salehian, who worked on product infrastructure and model behavior post-training xAI and previously worked at Twitter\/X, said last week<\/a> he was leaving to \u201cstart something new.\u201d\u00a0<\/p>\n
