OpenAI Releases Codex Mac App as Multi‑Agent Command Center

The launch is paired with expanded access to drive rapid adoption.

Overview

  • The macOS app orchestrates multiple coding agents in parallel with project threads, isolated Git worktrees, a reusable Skills library, and scheduled Automations, and it is powered by the GPT‑5.2‑Codex model for coding tasks.
  • OpenAI is temporarily making Codex available to ChatGPT Free and Go users and has doubled rate limits across Plus, Pro, Business, Enterprise, and Edu plans.
  • The company reports more than one million developers used Codex in the past month, with usage doubling since the December GPT‑5.2‑Codex update.
  • The desktop client is available now on macOS, works alongside the CLI and IDE extensions, includes sandboxing with permission controls, and a Windows version is planned for a later release.
  • The move targets rivals such as Anthropic’s Claude Code and Google’s tools, as Apple’s new Xcode update adds agentic coding support for external agents including Codex.
