Overview
- Codex is available now in the Microsoft Store for Windows 10 version 19041 or later across ChatGPT Free, Go, Plus and Pro plans.
- The release includes a Windows‑native sandbox with PowerShell support so agents can operate in real developer environments with containment.
- Developers can run multiple AI coding agents in parallel, with each task isolated in its own worktree to prevent conflicting changes.
- Skills and built‑in automations connect agents to tools and workflows to take on repetitive tasks such as bug testing and code validation.
- Session history syncs to OpenAI accounts for cross‑platform continuity, and the Windows sandbox implementation has been open‑sourced as interest tops a 500,000‑person waitlist and about 1.6 million weekly active users.
