From the post

I've been early testing Sonnet 5.5 and I need to talk about what just happened. I wrote one detailed spec and handed it over. What came back is a fully interactive 3D night drive through the backstreets of a Japanese city. One HTML file. Nothing loaded from the internet. You double-click it and you're there. Here's what's inside: > A tiny invented 80s hatchback with pop-up headlights, working wipers, brake lights, turn signals and real suspension that rolls in the corners > Wet asphalt that reflects every neon sign, streetlamp and headlight, with puddles that ripple under the rain > A commuter train looping over a steel viaduct, throwing window light onto the street below > A level crossing with flashing lights and a bell, where the car actually stops and waits for the train > An izakaya alley with red lanterns and steam rising through the colored light > A canal with willows, a hillside shrine, a ramen stall with a cook working inside > A full dusk-to-dawn cycle: violet sky, heavy rain with thunder, midnight mist, then the first blue light of morning > A synthesized soundscape, down to a lo-fi loop playing from the car radio The car drives itself. Grab the keys and it's yours. Let go, and the autopilot takes it back. A year ago this would have been a small team and a few weeks of work. Now it's a prompt and some patience. If this is where the frontier is heading, I'm all in. Demos: https://t.co/i4Ik0wHhOj
