One prompt, 30 hours autonomous: AI builds a working computer from logic gates
mattshumer_ · x · 2026-09-28
Matt Shumer showed off a result from ultracode mode: from a single prompt, a model autonomously spent 30 hours building a working computer entirely in code — starting from individual logic gates, designing the CPU, memory, an assembler, a tiny OS, and a real game that runs on those gates (not JavaScript pretending), with the whole system visualized. He teased that his next demos will be even crazier.
