This expansion to Windows allows a broader user base, including developers utilizing Microsoft’s operating system, to access and leverage the application’s AI-driven coding capabilities.
The Windows version of Codex supports the coordination of multiple AI agents for coding tasks, a feature upgraded in early February.
