Jason Wei from OpenAI's Mind Chain project team revealed that he works nearly 16 hours a day. Industry insiders point out that the issue of overwork among OpenAI team members has long existed, as evidenced by GitHub contribution records showing employees working around the clock. Earlier, when a core employee resigned, they mentioned that the company's work intensity far exceeded the 996 working model. After the explosive popularity of ChatGPT, the balance between work and life for employees has become even more pronounced. Analysts believe that the sense of mission within the company and the work pressure brought by ChatGPT are the reasons behind this self-driven overtime.
