I Built a High-End Animated Website in Codex with GPT-5.6

In this video, I’ll show you my complete workflow for creating an animated beverage website entirely inside Codex using three GPT-5.6 models: Luna for planning, Sol for design generation, and Terra for refining and polishing. We’ll explore how to develop the product concept, create a PRD, generate visual assets, build a strong design system, add animations, and refine the final landing page. You’ll also learn how to use effort and speed settings, write better prompts, and create a complete website from a single detailed prompt. The prompt and template are available in the description.
