As I understand it, ITAR regulations for export controls have just been applied to any form of Mythos.
These are overseen by U.S. Departments of State and Commerce, and forbid foreign nationals from access to any form of Mythos, either within or outside the U.S.
Only U.S. citizens and immigrants that are holders of a "green card" may now access Mythos.
It appears that Anthropic does not have internal controls to implement these restrictions in any form, so the only option was to shut Mythos down.
Penalties for ITAR violation can reach ten years in prison and a million dollars per violation. (I can post a link to those details if there is any interest.)
As long as Anthropic is a U.S. company, there is no escaping this.
> Only U.S. citizens and immigrants that are holders of a "green card" may now access Mythos.
It was my understanding that not even green card holders may access Mythos. Normally when restrictions like this are put in place, you need a exemption as a green card holder. A geen card is just a permit to live and work in the US. Its not the same as citizenship.
> Security Clearance: Green Card holders are generally prohibited from jobs that require high-level security clearances or sensitive government/military roles reserved exclusively for U.S. citizens.
That's not true. ITAR and security clearance are entirely separate regulatory regimes. For ITAR purposes, being a permanent resident is good enough. I used to work for a defense contractor, and we hired plenty of green card holders. They were not in general assigned to work that required a clearance, but plenty of defense-sensitive, ITAR-controlled work is done by green card holders.
Were those ITAR export controls chosen because they really are the most appropriate tool for this particular case, or because they could be deployed at a very short notice?
Individuals can leave, but the company cannot transfer restricted intellectual property.
Europe has extradition treaties, so the U.S. can force anyone in Europe back to the U.S. for criminal indictment who demonstrates inappropriate possession of this technology.
