Lilian Weng, who recently left Thinking Machines citing startup-related stress and illness, is rejoining OpenAI to focus on using AI to develop new models (recursive self-improvement).

This move highlights a grimmer reality in the AI industry. As noted in a recent essay by Nathan Lambert, the intense LLM arms race is leading to severe burnout among professionals, with many working 100-hour weeks. The pressure to stay relevant during a closing window of technological opportunity is forcing individuals to sacrifice life balance and health, raising concerns about the industry's long-term sustainability.
