Claude versus "GPU'less AI architecture" reasoning competition

The post reports a 1,186-question contest between SapienTronic AI (previously Minotaur AI) and Claude across a 69-part water-treatment plant scenario, bridged logic puzzles, and a trick question about rules only an endless town can obey. SapienTronic AI answered all 1,186 correctly in about 28 seconds on a laptop with no tokens or GPU, while Claude (Fable 5.1 and Opus 5.5) got 1,185 right, used about 528,041 tokens over roughly 28 minutes, and made one confidently wrong answer by treating a contradictory plant state as real. The author argues that a single confident mistake matters because it cannot be identified, can propagate through chains of decisions, and is not the kind of checkable evidence safety standards require.
