Cat Wu, product lead for Claude Code and Cowork at Anthropic, has just announced her move to OpenAI, only about a day after her departure from Claude Code. Cat Wu previously worked on developing Claude Code from an internal prototype to a commercial product, gaining experience in developing AI programming agents and general-purpose working agents.
OpenAI and Anthropic are intensifying their competition in the enterprise AI market, and this personnel change has attracted significant market attention. A recent report from venture capital firm Menlo Ventures shows that Anthropic now accounts for 55% of enterprise large-scale model API spending, leading OpenAI's 31%. Cat Wu's joining OpenAI may help accelerate the iteration of its Codex and general-purpose agent products, bringing its experience in complex task execution, model evaluation, and enterprise deployment to a wider range of applications. As cutting-edge model capabilities continue to improve, product talent with experience in model evaluation, agent design, and commercialization is becoming a crucial resource sought after by AI giants.
