Blogger aakashgupta stress-tested Gemini 4 Argon's frontend generation: five prompts of 50 words each, sent once with zero fixes, produced five playable apps in 328 seconds for $0.37 total at list price.

Results:

Every prompt followed the same four-part structure: what to build in a single HTML file, allowed libraries, how it should feel, and phone-portrait sizing. The author declined to grade Google's official demo of building a Slides deck from 80,000 NASA files since it can't be reproduced; his own runs all went through Google's API on Oct 14, with prompts and apps publicly inspectable.
