Overview
- The macOS app serves as a command center that runs multiple AI coding agents in parallel across projects, using threads and Git worktrees to keep changes isolated.
- A built-in Skills library and scheduled Automations let teams extend workflows beyond code, from generating assets to triaging bugs and running background tasks.
- Security controls include a configurable system-level sandbox, permission prompts for sensitive actions, project-level rules, and native Git review of diffs and pull requests.
- Access is temporarily widened to ChatGPT Free and Go users, and paid tiers receive doubled Codex rate limits across the app, CLI, IDE extensions, and cloud.
- The release is powered by GPT‑5.2‑Codex, with OpenAI citing over one million monthly developers and usage growth since December, and a Windows version is planned as it competes with Anthropic and Google.
