But I wonder how they were able to release Sonnet 5 during the period when even people inside Anthropic were legally barred from using Mythos/Fable?

Iirc the ban only applied to non-Americans. While anthropic found collecting citizenship information on all customers too burdensome, it's a much smaller lift to collect such info for your own employees.

So I'm assuming at least a subset of employees could continue using the models during that time.

		Although the ban was only for non-Americans, Anthropic said that they'd also restricted access to their own employees internally, because they had no other realistic way to apply the government's orders. I guess it's possible they were lying, but seems unlikely.
