  Here is the gov's argument. Hard to evaluate whether the concern is justified—or just politics toward an American company this government often whacks—without the specifics of the jailbreak. Also not clear why they chose to regulate via a blunt and hard-to-follow export control.

  If you're ever wondered what AI regulation will look like if implemented, this is de facto what to expect on the current trajectory. If the government has control over what models eventually get released, then companies will spend months and months debating with the government

• @benpielstick Ben Pielstick on x

  It seems very likely to me that the non-compliance on the part of Anthropic the government perceives and is confused by from a safety-focused company, is because the government doesn't understand that what they're asking for is stupid and/or impossible.
