Arena engineers race to build the same taco truck app from one napkin sketch in Agent Mode
arena · x · 2026-09-05
Arena ran a head-to-head experiment: two of its engineers, Graham and Logan, each used Agent Mode to independently build the same taco truck waitlist app from a single napkin sketch, plus a build-vs-buy recommendation. The results are public on Agent Arena, where users can rerun the same prompt against top agents themselves.
