Fable 5 and Mythos are back: US lifts export controls on Anthropic's top models

[NeutrinoX54]

The Commerce Department has lifted its export restrictions on Anthropic's most powerful models and access to Claude Fable 5 and Mythos 5 started coming back from July 2. Cursor and Perplexity have already switched Fable 5 back on, and apparently it immediately tops CursorBench while also being the most expensive model per task. Anthropic put out a short statement thanking users for their patience

Worth remembering how we got here. Reports of researchers jailbreaking Fable 5 spiralled into a full government clampdown, and an academic quoted by Al Jazeera reckons those reports were inflated well beyond their actual significance and that Washington realised it had overreacted. Anthropic's own experts had warned Mythos could hack the systems underpinning most modern computing, which is what set banks and agencies scrambling in the first place

The precedent question is the one that matters long term. One analyst put it bluntly, does the US government now need to approve every frontier model release? OpenAI is already staggering GPT-5.6 through a small set of trusted partners under government pressure, so the answer is looking uncomfortably close to yes

I am genuinely torn on this one. Models that can plausibly attack critical infrastructure probably should get a second look before global release, but an informal regime where access depends on how good your relationship with the White House is feels like a terrible way to govern anything. Where does everyone land?
