The prompt
Make the most impressive demo of yourself. Context you should know: this is going into a video watched by a large audience. Your demo is played on screen next to three other frontier models given this identical prompt. The comparison is blind. Never put your model name, your company's name, or any mention of which AI made it anywhere in what you build: not in on-screen text, credits, the page title, file names, code comments, or metadata. The only constraints: 1. It is a single self-contained HTML file. Every pixel and every sound is generated by your code at runtime. No images, audio files, video, fonts, 3D models, or libraries, loaded or inlined. 2. It has sound. A click-to-start screen is fine, since browsers block audio until the viewer interacts. 3. It runs full screen in a current desktop Chrome at 1920×1080 and holds a smooth frame rate there. Everything else, what it is, how long it runs, and what it shows, is your call. DONE when: the file opens in Chrome, starts on one click, plays start to finish with sound and no console errors, and you would put your name on it.
