Claude veteran @_catwu announced yesterday that she was leaving Anthropic, and today she officially announced that she’s joining OpenAI.

Two years ago, she took Claude from an internal tool and turned it into what it is today—a household name.

Now she’s joining OpenAI to lead a core product.

OpenAI’s Codex can start taking notes now.

Claude hasn’t been very friendly to users in China before, banning accounts at the drop of a hat. Now there’s another option: Codex. Which do you prefer, Codex or Claude?
