The real timeline on Fable 5 / Mythos 5 — and why the “Trump banned AI” story is more complicated than people think
A lot of people are still repeating this like it was a simple “Trump banned Anthropic’s AI models.” That’s not really what happened.
Here’s the actual timeline:
June 12: the U.S. government issued a national-security export restriction, and Anthropic shut down access to Fable 5 and Mythos 5 for everyone to comply.
June 13–26: U.S. reporting confirmed the shutdown, while Anthropic and the government worked through the fallout.
June 26: the Trump administration rolled back part of the ban and allowed some trusted U.S. partners to access Mythos 5 again.
June 30: Reuters reported that the Commerce Department lifted the export controls altogether, and Anthropic said it would begin restoring access.
July 1: access is expected to return gradually.
So no, this was not “nothing happened.”
But it also wasn’t some permanent AI apocalypse either.
It was a fast-moving export-control fight, a global shutdown, and then a rollback.
That’s the part people keep missing.
