Overview
- The macOS app serves as a command center where developers run multiple agents in parallel, group work by project, and review diffs or open changes in their editors.
- Codex supports worktrees so agents can operate on isolated copies of a repo, adds a Skills library for tool-connected workflows, and offers Automations for scheduled background tasks with review queues.
- OpenAI is temporarily doubling Codex rate limits across Plus, Pro, Business, Enterprise, and Edu plans and is opening access to ChatGPT Free and Go users for a limited time.
- The company recommends GPT‑5.2‑Codex for coding tasks and GPT‑5.2 for analysis or writing, with options to adjust thinking intensity and agent personality.
- OpenAI says over 1 million developers used Codex in the past month, and the launch is widely framed as a catch‑up move to Anthropic’s Claude Code, which already offered a macOS app.
