OpenAI just made one of its clearest product moves yet: ChatGPT and Codex are no longer meant to feel like two separate products.

During its latest Intelligence at Work event, OpenAI signaled that Codex's core capabilities are moving deeper into the ChatGPT experience. The message is simple but important: ChatGPT remains the familiar conversational entry point, while Codex becomes the execution layer that can actually build, analyze, transform, and iterate on work.

OpenAI has been moving fast again.

In just a few days, the company introduced GPT-5.4, launched ChatGPT for Excel in beta, and rolled out Codex Security in research preview. On paper, these look like three separate product announcements. In reality, they feel like one clear strategy.
