Episode Details

Three days after Anthropic launched Claude Fable 5 — their first publicly available Mythos-class model — the US Department of Commerce suspended it, blocking even the company's own foreign-national employees from accessing it. The emergency action wasn't about what the model might say, but what it could do autonomously. This episode unpacks the confusion around the Fable-Mythos relationship, the novel fallback safeguard that silently routes sensitive queries to a less capable model, and what it means when capability class becomes a regulatory category. We trace the three-week scramble from suspension to clearance, and explore why this moment marks the first time export controls have been applied to a general-purpose AI model post-launch — not to hardware or chips, but to the model itself.
