In November 2025, AI coding tools went from “halting and clumsy” to surprisingly capable. Suddenly they could produce whole, working apps from minimal instruction, in ways they simply couldn't before.
This experiment makes that shift visible. We gave 22 AI models the same exact prompt to build a working analog clock from scratch, then ran each model five times independently.
