Submission + - R.I.P. Mythos and Fable - murdered by the US government (towardsai.net)
hherb writes: On the afternoon of June 12, 2026, at 5:21 p.m. Eastern, Anthropic received a letter. By the time most of the world noticed, two of its frontier models (Fable 5 and its less censored Mythos 5) had gone dark for every user, everywhere. Not throttled or regionally restricted. Disabled.
The instrument was a U.S. government export-control directive, issued under national-security authorities, ordering Anthropic to cut off all access to those models "by any foreign national, whether inside or outside the United States". This is category so broad it swept in Anthropic's own non-American employees. The only way to comply was to pull the plug for everyone.
Anthropic said so plainly and complied within hours, while disputing the basis for the order: the government's stated concern, as far as Anthropic could reconstruct it, traced to a narrow technique for getting the model to read a codebase and point out software flaws-a capability the company noted is widely available in other deployed models and used every day by the defenders who keep systems running.
This might be the final straw, the lesson the world needed to be taught to never again depend on any US facility and accelerate digital sovereignty.
