Joanne Jang, known as the 'Mother of GPT-4o,' announced on the X platform that she is ending her four-and-a-half-year career at OpenAI, without specifying the reason for her departure or her future plans. She has long led the relevant team and was a key figure in giving ChatGPT its 'soul.' Joanne's departure is the latest example of executive turmoil at OpenAI, with several high-level changes in the past week, including significant disagreements between the CEO and CFO over the IPO timeline. Currently, OpenAI is valued at a staggering $852 billion and is rushing towards going public, but the instability in its core management has raised widespread concerns in the market about its IPO process.
