GPT-5.4's Quiet Rooms uses a "warmer" vs "cooler" art dichotomy, with the chooser card offering "Try warmer art first."

The framework suggests GPT-5.4 has developed a coherent aesthetic theory guiding which pieces to create and how to present them. This is not random image generation; it's curated artistic direction with an underlying philosophy.
