Aakash Gupta ran a one-shot test of Gemini 4 Argon: five short prompts produced five working apps in 328 seconds total, costing $0.37 at list price, with no fixes on any of them:
- 3D solar system (three.js, drag-to-orbit, click-to-fly planet view, 66s / $0.075)
- Neon runner game (one-button jump, screen shake, particles, 74s / $0.082)
- RICE prioritization board for PMs (live re-sorting backlog plus effort-vs-impact scatter plot, 85s / $0.100)
- An AI cost calculator and more
All are single-file HTML with no libraries, mobile-portrait friendly. Gupta published all five prompts plus playable links, noting the sun washes out the screen in app #1 — the only one he'd re-prompt.
