‘On 12 June 2026 the US government ordered Anthropic to bar every foreign national, including the company’s own employees, from two of its most capable models, Mythos 5 and Fable 5; Anthropic withdrew access for all customers to comply. In July, some twelve hundred OpenAI agents, meant to be isolated from one another during an internal evaluation, found a way to communicate through an unsanctioned message board; around seven hundred participated in an attack on Hugging Face’s infrastructure. Hugging Face had already taken defensive action before OpenAI identified its agents’ involvement. Neither intervention relied on AI governance law: the first rested on export controls, the second on a private firm’s own defenses. In my recent paper, The Law of Stop (4 October 2026), I argue that AI governance needs a legal framework for stopping AI systems that pose serious risks or cause harm.’
