Lilian Weng 是 AI 安全领域关键人物，她的去向直接影响两家重要机构的人才格局，从业者值得关注。
Techcrunch: Lilian Weng is leaving Thinking Machines Lab for OpenAI, moving from co-founder role into a narrower research post.
Weng said startup stress and workload had pushed her health beyond what she could sustain, after months of considering the decision.
She also said a scoped role in a more predictable place, without co-founder responsibility, would suit her better.
OpenAI says she will lead a top-level group focused on accelerating internal research into recursive self-improvement.
Weng returns with direct institutional knowledge from 2018 to 2024, including GPT-4 development and leadership of Safety Systems.
Her appointment puts a former safety leader near work that OpenAI’s Preparedness group is already hiring researchers to manage.
For Thinking Machines Lab, the departure deepens a retention problem, with only 2 of the original 6 co-founders remaining.
