OpenAI’s former vice president of research and security, Peking University talented woman Weng Li officially announced her resignation due to physical overdraft. Lilian Weng, co-founder of American AI unicorn Thinking Machines Lab and former vice president of research and security of OpenAI, recently announced her resignation on the X platform. She revealed in her resignation letter: "In the past seven months, I have been sick more frequently than at any other time in my life. The continuous pressure and workload have exceeded what my body can bear." It is reported that Weng Li considered taking a position with narrower responsibilities, but after weighing it, she finally believed that "if I cannot devote 100% to the work I am responsible for, it means that I have not done the job well." Weng Li admitted that she still loves the field of AI, but in the future she hopes to join an organization with a stable and controllable work rhythm and clear division of job responsibilities, instead of continuing to be a co-founder of a startup company. She wrote at the end of the letter: A future worth building is people-centered. Regarding this resignation, the company's founder and CEO Mira Mulati responded to Weng Li's tweet, recognizing her choice to put health first and thanking her for all her contributions to the company during her tenure. It is understood that Weng Li graduated from Peking University and joined OpenAI in 2018. Starting from the robot team, he later established and led a security system team of more than 80 people from scratch, and participated in the security work of models such as GPT-4, GPT-4o and o1. In August 2024, he was promoted to Vice President of Research and Security of OpenAI and resigned in November of the same year. Later, in February 2025, she co-founded Thinking Machines Lab with former OpenAI CTO Mira Mulati and others. The company completed a US$2 billion seed round of financing in July, with a post-investment valuation of US$12 billion. via cnBeta.COM - Chinese industry information station (author: Source: Kuai Technology)
