OpenAI's Codex is "now" on Windows (thenewstack.io)

OpenAI has announced that its successful Codex agentic coding app is now available for Windows users, following its impressive launch on macOS earlier this year, which saw over 1 million downloads within the first week. With more than 500,000 developers on the waitlist, the Windows version is expected to attract significant interest. This iteration is designed not only for compatibility but also tailored to real Windows development environments, allowing users to leverage familiar tools and workflows. It offers native sandboxing, supports the Windows Subsystem for Linux, and incorporates OS-level security controls for environments like PowerShell. Structurally similar to its Mac counterpart, Codex for Windows maintains its focus on agent management over code, featuring an interactive view that acts as a command center for user-agent interaction. Built on OpenAI’s latest coding-specific models, including GPT-5.3-Codex, it allows flexibility in model selection based on task requirements. While it retains core functions like skills, automations, and support for worktrees, it also introduces Windows-specific features, including a WinUI skill for app developers. This release marks a significant step in expanding accessibility to cutting-edge coding assistance within the developer community.
