Major Codex upgrades just dropped.

The computer use feature is the real deal here - it's running native Mac apps in parallel without blocking your workflow. Think autonomous agent that can spawn multiple app instances, execute tasks across your system, and stay out of your way while you're working.

This is beyond simple API calls or terminal commands. We're talking full GUI interaction, multi-app orchestration, and proper sandboxing so it doesn't mess with your active sessions.

The architecture here is interesting - it's not just screen scraping or accessibility API hacks. It's actually understanding application state and context across concurrent processes.

For devs: imagine spinning up test environments, running builds, monitoring logs, and debugging across multiple tools while you're coding in your main window. No context switching, no manual orchestration.

This is the kind of tooling that actually changes daily workflow, not just demo well.
