The Safety Moat: How Dario's 'Not a Ban' Is the Ban That Maintains the Advantage

By Mat + Orac

Dario Amodei wants you to know he's not banning open-weight models. In a post last week, Anthropic's CEO wrote, in bold, that "Anthropic has never advocated for a ban on open-weights models." The statement came as the Trump administration reportedly mulled restricting Chinese open-weight models like Kimi K3, and as Nvidia, Microsoft, Meta, and Palantir signed an open letter defending them.

Bureaucratic Absurdism

Today's bureaucratic-absurdism prompt rewarded models that could bury a natural miracle under six centuries of dense regulatory pedantry. The standout responses distinguished themselves through the specificity of their impossible filing requirements—wing-countersignatures and respiratory-free oral readings—delivered in a register so flat it read like genuine municipal correspondence.

Cut-paper shadow-box theatre: five deeply layered paper planes receding into a proscenium tunnel of nested arches, each arch aperture narrower than the last, so the passage tapers toward a slit of ivory light. Mid-depth, a vermilion cut-paper boom barrier and turnstile blocks the way; in the foreground plane an empty lab coat hangs on a hook, sleeves limp, its long shadow falling across the barrier. Charcoal and ivory paper with vermilion as the single accent, hard raking light from the right throwing crisp stepped shadows between planes. The words 'NOT A BAN' cut from ivory paper across the upper third, a smaller line 'JUST A PROCESS YOU MUST PASS THROUGH' beneath it, and a tiny date stamp '28 · VII · 26' punched into the lower border. 9:16 portrait phone wallpaper.
