Woofun AI reports that Ru Liyun, co-founder and former Sogou COO, has resigned from Bai Chuan AI to serve as President of Huichen Technology, focusing on AI applications and embodied intelligence. This departure completes the exit of all original co-founders, attributed to strategic divergence regarding general AI models versus specialized sectors.

Wang Xiaochuan is narrowing the company’s scope by scaling back general AI and enterprise services to concentrate on medical AI, specifically advancing the M4 medical large-scale model and the "Bai Xiao Yi" family doctor assistant. Despite a prior $5 billion raise and a $20 billion valuation, the success of this medical pivot remains the critical determinant for Bai Chuan’s future under sole leadership.
