The Unintended Consequences of Codex’s Comeback

OpenAI’s Codex - which was once pitched as a coding agent for developers and is now being framed as a general-purpose agent for knowledge workers - is having a moment, as OpenAI chief revenue officer Denise Dresser put it on Tuesday. As I wrote about in this story from Tuesday, lots of developers are making the switch from Anthropic’s popular Claude Code tool to Codex, as OpenAI has made its models and the Codex app better for longer-running and complex tasks in recent months, they say. Engineers at OpenAI have seen that productivity boost perhaps than anyone else.
