DeepSeek V4.1 Flash coded this rainy neon Tokyo street at night in one HTML file. Zero images, zero libraries. 4.5 minutes of generation, $0.05. It needed one fix. The exact prompt, try it on your model: "A rainy neon street in Tokyo at night seen from street level: layered parallax buildings, glowing flickering signs, wet asphalt with neon reflections, rain with splashes, a train passing on an elevated track every few seconds, drifting fog and a slow camera dolly."
