Federico Viticci blogs about the new Codex app from the perspective of his early preview of Sky last year:
It also helps that computer use in Codex is exquisitely designed – not a surprise given OpenAI’s design team and the pedigree of the team behind this feature. The flow for granting permissions to the plugin is the best I’ve ever seen in a third-party Mac app – and it comes directly from Sky, which had the same onboarding experience. What Sky didn’t have is the new virtual cursor: the Codex team designed an entire system for it where the cursor can wiggle to show when the model is thinking, takes playful paths, and derives its color from the system’s wallpaper.
I’m impressed with both the design and functionality. I’ve been experimenting with using it to test features by letting it click around in the iOS Simulator. It works perfectly.
The virtual cursors are clever too. You can have multiple Codex tasks busy automating work behind the scenes while you use your Mac’s real cursor for whatever you’re normally doing.
