I Built a Better Codex Pet Than OpenAI Did
Sometimes you just have to let the agent cook. Mika vs. a multi-billion-dollar corporation, and a stupid little desktop pet.

Mochi is a Linux desktop companion designed to feel like a living creature on your screen, independent of the applications you use. In contrast, OpenAI's Codex Pets is a simple status light with an animated tail that reflects the status of an AI coding agent.

Its architecture separates what is visible from what is actually happening, providing a more sophisticated and independent experience compared to the Codex Pets.
