Lilian Weng quay lại OpenAI sau khi rời Thinking Machines Lab vì lý do sức khỏe

The Huoxing Finance report states that on July 30, Lilian Weng, co-founder of Thinking Machines Lab, resigned due to health reasons (repeated illness over the past seven months and excessive entrepreneurial pressure), only to return to OpenAI just days later. She will lead a team focused on research into "recursive self-improvement," a topic she has recently explored in depth on her blog, aiming to leverage AI to develop more powerful systems. Previously, Weng served as Vice President of Safety Research and Head of the Applied AI Research team at OpenAI. In early 2025, she co-founded Thinking Machines Lab alongside former OpenAI CTO Mira Murati and others. This rapid return highlights the mobility of top AI talent between high-intensity frontier labs.
