PANews reported on June 14 that David Sacks, co-chair of the U.S. President's Council of Advisors on Science and Technology, shared his views on Anthropic's suspension of foreign citizen access to Claude Fable 5 and Mythos 5 in a tweet, based on conversations with people inside and outside the government.

Earlier this week, Anthropic publicly released its Mythos-level model under the commercial name "Fable." "Fable" is a Mythos model with added safeguards. A partner highly trusted by both Anthropic and the US government discovered a way to bypass these safeguards while testing "Fable." Administrators demanded a fix or the model be removed, but this was refused. Anthropic subsequently downplayed the severity of the incident in a blog post, a stark contrast to its self-proclaimed "AI security company" image. To prevent the unpatched model from falling into the wrong hands, the government was forced to impose regulations on the model. Currently, the government hopes Anthropic will fix the issue, lift the restrictions, and resume normal releases as soon as possible.
