OpenAI's new Codex AI pets, which sit in the corner of your desktop and display thought bubbles to inform you of your agents' activities. These pets can be spawned by the "/pet" command and choose from eight pre-made versions. The thought bubbles indicate when an agent is awaiting approval or is awaiting fresh instructions, and if the agent has finished a task and is ready for a new prompt, a green checkmark indicates readiness. The Codex pets have been praised for their practical utility, allowing users to feel more informed about their AI agents' actions.
