The biggest personnel change in the AI world today On the eve of Anthropic's trillion-dollar IPO, OpenAI poached Claude Code's top female executive! Cat Wu, of Chinese descent, graduated from Princeton's Computer Science department and worked as an early employee at Scale AI and a partner at Index Ventures. After joining Anthropic in 2024, she built a reinforcement learning environment using a beta version of Claude Code, spending dozens of hours without writing a single line of code. She was immediately captivated and switched to working on Claude Code. Now she has officially joined OpenAI to oversee core products. It's worth noting that OpenAI's Codex is Claude Code's biggest competitor.
