OpenAI’s Codex is now in the ChatGPT mobile app

OpenAI will let users access Codex from the ChatGPT mobile app; the RSS snippet says Codex can write code and use apps on a computer, but the post does not disclose launch timing, pricing, or the full mobile feature scope.

Why it matters: OpenAI added Codex access to ChatGPT mobile, a mid-weight product update. HKR-H/K/R pass through the mobile coding-agent hook, concrete app-control claim, and developer workflow nerve; missing timing, pricing, and support scope keep it at the featured floor.
